Answer:
When talking about dizygotic and not monozygotic twins, they share the uterus, but they do not share the bag, nor the nutritional sources nor the placenta, if they can share the same amniotic sac depending on how far one ovum separated from another.
Thus, being two different ovules and fertilized by two different sperm (unlike homozygotes, which is an ovum fertilized by a sperm that divides into two and share the same development medium) they present the same genetic load but not the expression of this or the same phenotype since they develop in two different environments, this was raised in certain investigations and it was presented that even the different location that they present in the uterus can influence the different phenotypic manifestations of the genome.
There are studies that maintain that immunosuppressive treatments in grafts between monozygotic twins do not make sense and should not be done since it was experimented in certain cases and the patients had no problem of rejection in allografts, since it is argued that they have the same genotype and this genotype. It is usually expressed in the same way, therefore it is rare that the immune receptors and the immune response differ and consider something foreign to a tissue that presents histocompatibility almost 100 percent.
In contrast, in dizygotes it is different, allografts are made but under protocol immunoregulatory treatments that prevent rejection of the allogeneic implant or graft. Thus, certain researchers argue that having developed other phenotypes between twins, this causes the histocompatibility complex to express itself differently and thus the immune response does not recognize it as its own.
Explanation:
With the wording then we can conclude that the dizygotic twins corrupt the myth that transplants of tissues or organs can be performed without immunomodulatory treatment, if or if drugs must be administered to avoid rejection of said tissue or organ.

Which of the following illustrates intraspecific competition? A sea gull swooping down to snatch a fish from the water's surface Male red-winged blackbirds defending limited nesting sites from other males A butterfly feeding on the nectar of a daffodil flower A tick and a flea sharing a dog's back
Answer: Male red-winkled black birds defending limited nesting sites from other males.
Explanation: Intraspecific competition is defined as a competition between two individuals from the same species. There are two types of intraspecific competition which are interference intraspecific competition and exploitation intraspecific competition. For the purpose of the answer provided above, interference intraspecific competition is discussed.
In interference intraspecific competition, the species establish hierarchies through aggressive behavior in which one or more individuals within the population holds a dominant status over the others. These individuals limit or prevent access of more subordinate individuals to a resources through direct interactions.
Here, only those individuals who are dominant or holds territories will increase their production success. Example of this is in when two winkled black birds establishes a territory of nesting sites, thus limits the access of this nesting sites thereby defending the nesting sites from other males.
Final answer:
The scenario that best illustrates intraspecific competition is 'Male red-winged blackbirds defending limited nesting sites from other males,' as it involves competition among members of the same species, which defines intraspecific competition.
Explanation:
Intraspecific Competition Illustrated
Among the provided scenarios, the one that illustrates intraspecific competition is: Male red-winged blackbirds defending limited nesting sites from other males. This is because the competition is occurring between members of the same species, which is exactly what intraspecific competition entails. Male red-winged blackbirds will aggressively defend their nesting areas to ensure that they have a place to attract mates and raise their offspring. This competition over resources—like territory—results in natural selection, improving the species' adaptations over time.
On the other hand, interspecific competition happens when individuals from different species compete for resources. This can lead to one species out-competing the other, potentially causing the less adapted species to move away, adapt through character displacement, or go extinct due to reproductive and survival disadvantages.
The competitive exclusion principle further explains this phenomenon, stating that two species competing for identical resources cannot coexist at constant population values; one species will out-compete the other. These types of competition are significant evolutionary forces that impact biodiversity and ecosystem structure.

Please select all correct answers regarding its mechanism of action and application. Multiple correct answers are possible, and partial credit will be given.
A. CRISPR sequences in bacteria resemble those from bacteriophage and plamid DNA.
B. For reverse genetics studies, CRISPR/CAS can be used to replace wildtype alleles with mutant alleles which can knockout the function of the target genes.
C. CRISPR is a DNA sequence in the bacterial chromosome.
D. The guide RNA directs CAS to specific DNA sequences.
E. The CRISPR/CAS system was discovered in bacteria, and its natural function is the equivalent of an immune system in bacteria for "remembering" viral infections and for attacking viral DNA in future infections.
Answer:
A. CRISPR sequences in bacteria resemble those from bacteriophage and plasmid DNA. (The CRISPR sequences are derived from previously invading bacteriophages and pladmids.)
B. For reverse genetic studies, CRISPR /CAS can be used to replace wild type alleles with mutant alleles which can knock out the function of target genes. (CAS 9 introduces double strand break (DSB) in the target sequence which is then repaired by non homologous end joining (NHEJ). NHEJ causes deletion, insertion or frame shift mutation leading to knock out of the target genes.)
C. CRISPR is a bacterial sequence in the bacterial chromosome. ( The sequences are derived from bacteriophages that had infected the bacteria defore.)
D. The guide RNA guides CAS to specific DNA sequences. ( The guide RNA directs CAS nuclease to the target sequences for editing.)
E. The CRISPR/CAS system was discovered in bacteria, and it's natural function is the equivalent of an immune system in bacteria for remembering viral infections and for attacking viral DNA in future infections. (The CRISPR/CAS system provides acquired immunity to bacteria.)

Centrifugation of a cell results in the rupture of the cell membrane and the compacting of the contents into a pellet in the bottom of the centrifuge tube. Bathing this pellet with light yields metabolic activity, including the production of large amounts of NADPH and ATP. One of the contents of this pellet is most likely which of the following
A: Cytosol
B: Thylakoid/chloroplasts
C: Lysosomes
D: Golgi bodies
Answer:
B: Thylakoid/chloroplasts
Explanation:
Chloroplasts convert sunlight into food by photosynthesis, this process generates Adenosine Triphosphate (ATP) and Nicotinamide adenine dinucleotide phosphate (NADPH), thereby it is expected to find these compounds in the pellet
The process described in the question suggests photosynthesis is happening, which is performed by the chloroplasts/thylakoids (option B). These parts of the cell absorb light energy to produce ATP and NADPH which facilitates sugar synthesis.
Explanation:The process described in the question involves metabolic activity, including the production of NADPH and ATP, triggered by exposure to light. This is indicative of photosynthesis, a process primarily carried out in thylakoids, which are part of chloroplasts. So, the most likely content of the pellet is option B: Thylakoid/chloroplasts. These structures contain chlorophyll, the pigment required for photosynthesis, and are distinct to plant cells and some other organisms. They absorb light energy to produce ATP, which is used in the process of creating sugars and other organic compounds.

Why do some water masses in subsurface oceans have little or no oxygen? a. Large carnivores deplete oxygen in subsurface oceans via their high rates of oxygen metabolism. b. Rates of photosynthesis are low in overlying waters, limiting the availability of oxygen. c. Waters underneath the surface oceans are cold and thus have a limited capacity to carry oxygen in solution. d. Rates of photosynthesis are high in overlying waters, supporting high rates of respiration in waters that deplete the oxygen there.
Answer:
The Correct option is "D"
Explanation:
By and large there is accessibility of plenitude daylight on a superficial level which gives different tiny fish and diatoms a space to develop, which additionally accommodates thick algal sprout. These algal sprout are obtrusive to such an extent that their thickness may exhaust the oxygen level and furthermore can slaughter the microscopic fishes.
A 26-year-old woman in the clinic today for her annual physical examination. As you take her medical history, it becomes apparent that she is quite concerned about her risk for developing breast cancer. Her mother and a maternal aunt both developed breast cancer in their late 40s. She has heard that genetic testing can be done to see whether she carries "breast cancer genes."
***Assuming J.F. is talking about the BRCA1 and BRCA2 genes, what is the role that these genes have in the genetic mechanisms of breast cancer? (select all that apply)
a. BRCA1 and BRCA2 are tumor suppressor genes.
b. BRCA1 and BRCA2 are tumor promoter genes.
c. BRCA1 and BRCA2 are oncogenes.
d. BRCA1 and BRCA2 are proto-oncogenes.
Answer: the correct option is A (BRCA1 and BRCA2 are tumor suppressor genes).
Explanation:
BRCA1 and BRCA2 genes( breast cancer genes) are both tumor suppressor genes in every human expressed in breast cells and other tissue cells and it helps in
- repairing damaged DNA,
- regulate cellular growth and
- suppress the development of tumors . BRCA1 is located in chromosome 17 while BRCA2 is located in chromosome 13.
These genes in relation to genetic mechanisms of breast cancer, can be tested to know the possibility of the patient being susceptible to breast cancer in future or not. Mutation in either BRCA1 or BRCA2 or even in both genes makes the woman have a higher risk of developing breast,
Put the following steps in the correct order from 1-9
polypeptide chain is released from the P site
small ribosomal subunit binds to mRNA
initiation complex formed with addition of large ribosomal subunit
ribosomal subunits dissociate
codon recognition (non-initiating site)

Answer:
transcription of mRNA from DNA
small ribosomal subunit binds to mRNA
initiation complex formed with addition of large ribosomal subunit
translocation
codon recognition (non-initiating site)
peptide bond formation
ribosome reads a stop codon
polypeptide chain is released from the P site
ribosomal subunits dissociate
Explanation:
The above describes the process of translation in the ribosome. After transcription of DNA to mRNA, the mRNA is taken to the ribosome to undergo translation, here the mRNA binds to the small ribosomal subuits and to other initiation factors; binding at the mRNA binding site on the small ribosomal subunit then the Large ribosomal subunits joins in.
Translation begins (codon recognition; initiating site) at the initiation codon AUG on the mRNA with the tRNA bringing its amino acid (methionine in eukaryotes and formyl methionine in prokaryotes) forming complementary base pair between its anticodon and mRNA's AUG start codon. Then translocation occurs with the ribosome moving one codon over on the mRNA thus moving the start codon tRNA from the A site to the P site, then codon recognition occurs (non-initiating site again) which includes incoming tRNA with an anticodon that is complementary to the codon exposed in the A site binds to the mRNA.
Then peptide bond formation occurs between the amino acid carried by the tRNA in the p site and the A site. When the ribosome reads a stop codon, the process stops and the polypeptide chain produced is released and the ribosomal subunits dissociates.
Two cells in the same organism differ only in the number of chloroplasts they contain. The first cell has multiple chloroplasts, and the second cell has very few. What would most likely characterize these cells?
A. There would be no difference between the functioning of the cells because the chloroplasts are not essential cell structures.
B. The second cell would become larger because it would have fewer chloroplasts regulating its size and shape.
C. The second cell would shrink because it would not be able to store water and maintain cell shape.
D. The second cell would not be able to produce as much food because it could not capture sunlight.
Answer: D
Explanation: there right i just need the points
The correct answer is D. The second cell would not be able to produce as much food because it would not be able to capture sunlight.
What is the reason for chloroplasts being necessary ?Chloroplasts are essential for photosynthesis, in which plants and other photosynthetic organisms use sunlight to convert carbon dioxide and water into oxygen and sugars.
Without chloroplasts, the second cell would not be able to capture sunlight and convert it into energy, and therefore would not be able to produce as much food as the first cell.
A is incorrect because chloroplasts are necessary for photosynthesis and are therefore important cell structures. B is incorrect because the number of chloroplasts does not directly affect cell size.
C is incorrect because the number of chloroplasts has nothing to do with a cell's ability to retain water and maintain its shape. The photosynthesis is all done in the chloroplasts where the leaves are having the cells where the photosynthetic units.

How would you tackle the challenge of animating a "boneless" model such as, for example, a traditional RPG slime monster — or, alternatively, something like a snake or a detailed tail animation?
Answer:
1. Discuss why you think the unit exercise only caused you to create two bones for the model's hand instead of five.
R = why the prosthesis can be adapted according to the needs of each of the users.
2. How would the rigging (and animation) be more difficult if it did not include guide bones, pole targets, and other rigging elements that are not directly part of the mesh "skeleton"?
R = the bones of the fingers that are still present help us create the measurements of the missing fingers since in this way we create a more harmonic and sesthetic hand, and when these fingers are not present it is more difficult to create in the animation since it can be noticed a little deformed since the requests cannot be correct and the fingers can be seen in very different sizes from one to the other.
3. Describe the ways your model originally looked "off" in warp / skinning or in the animation / keyframe process
A = I would not know how to answer that because I do not have any key program to carry out the prosthesis but I can guide you a little bit about a prosthesis program which you can see in an animation program
The digital model of the affected hand was obtained using modeling techniques in Blender, Rhinoceros and Mesh to model conversion software in Solid Edge. As a result, a 3D digital model of the affected hand was obtained on which the mechanisms of the prosthesis to be implemented can be worked on and adjusted.
After developing the model of the prosthesis volume, measurements were taken and adjusted to the plaster model that was previously obtained. Figure 13 shows how the prosthesis model was fitted to the plaster hand model. Subsequently, with the measurements obtained from this model, the prosthesis mechanisms are designed for the three missing digits in the user's hand.
4. Imagine that you are creating a robot instead of a human character. What design changes could you make to the model in terms of rigging and skinning to make the character more "robotic"?
R = the physical aspect, and that the movements are more rigid and not so fluid to give the robotic touch, since currently robots move very fluidly and can make faster expressions and make it look more metallic and not treat it to do with such a humanoid aspect.
5. How would you face the challenge of animating a "boned" model, such as a traditional RPG slime monster, or alternatively a snake or detailed tail animation?
R = you have to make an animation character that looks gelatinous, as through the program you have to create a mass that looks translucent so that it can simulate that the character does not have bones, because if you make it a solid object we would be losing the effect that the character is gelatinous that is supported without bones.

Only red algae can grow in relatively deep regions of the ocean because red algae are: Select one: a. capable of absorbing carbon dioxide even from the carbon-dioxide-depleted deep waters and using the carbon dioxide to build sugars during photosynthesis. b. specialized for absorbing shorter wavelengths of light that penetrate deeper into the water for photosynthesis. c. able to perform chemosynthesis rather than photosynthesis. d. capable of absorbing ultraviolet light for photosynthesis, rather than visible light.
Answer:
b. specialized for absorbing shorter wavelengths of light that penetrate deeper into the water for photosynthesis.
Explanation:
There are two lights which are responsible for the photosynthesis in plants and algae i. e. red and blue light. These two lights are absorbed by the plants and algae in the process of photosynthesis while most of the light colors are reflected. In water red light remains in low depth while blue light penetrate deep into the water due to its shorter wavelength. So that's why red algae can grow due to the presence of blue light and photosynthesis occurs.
Correct Question and options:
Only red algae can grow in relatively deep regions of the ocean because red algae are:
a. capable of absorbing carbon dioxide even from the carbon dioxide deep waters and using the carbon dioxide to build sugars during photosynthesis.
b. specialized for absorbing longer wavelengths of light that penetrate deeper into the water for photosynthesis.
c. able to perform chemosynthesis, rather than photosynthesis.
d. capable of absorbing ultraviolet light for photosynthesis, rather than visible light.
Answer:
The correct answer is b. "specialized for absorbing longer wavelengths of light that penetrate deeper into the water for photosynthesis".
Explanation:
Red algae, also known as Rodophytes, are immobile organisms that inhabit the sea, but might also be found in freshwater and some of them can even be terrestrial. Due to its pigments, this algae is capable of absorbing sunlight in great depths, even much more than other types of algae. Rodophytes are photosynthetic organisms, which means that when they absorb sunlight they can transform it into energy.
Red algae´s coloration is due to the rhodoplasts that contain chlorophyll a, in addition to other pigments such as phycoerythrin and phycocyanin, that are phycobiliproteins. These last ones mask the chlorophyll and make a place to the characteristic algae´s red color.
Only red algae can grow in relatively deep-sea regions because they are specialized in photosynthesizing by absorbing longer light wavelengths that penetrate deeper into the water. Phycoerythrin is the one that absorbs the green wavelengths that reach deep regions and emits the red wavelengths of light. These proteins capture light energy and transfer it to chlorophylls during photosynthesis.
The enzyme phosphorylase kinase catalyzes a modification of glycogen phosphorylase that controls its activity. How does phosphorylase kinase modify glycogen phosphorylase?
a.adenylation, which transfers an adenosine from ATP to the phosphorylase enzyme direct AMP
b.binding to glycogen phosphorylase after hydrolysis phosphorylation, which transfers a phosphate from ATP to the phosphorylase enzyme
c.a conformational change driven by the energy released when ATP is hydrolyzed
Answer:
B
Explanation:
Phosphorylase kinase modifies glycogen phosphorylase through phosphorylation, transferring a phosphate group from ATP to glycogen phosphorylase and thereby activating it. This regulatory mechanism is central to glycogen metabolism and responds to hormonal signals indicative of the body's energy status.
The enzyme phosphorylase kinase modifies glycogen phosphorylase through a process called phosphorylation, which transfers a phosphate from ATP (adenosine triphosphate) to the glycogen phosphorylase enzyme. This modification converts inactive glycogen phosphorylase b into the active form, glycogen phosphorylase a. This conversion is regulated by hormonal signals such as epinephrine and glucagon, which trigger a cascade involving the activation of adenylate cyclase, an increase in cAMP levels, and the subsequent activation of protein kinase A (PKA). PKA then phosphorylates phosphorylase kinase, which in turn phosphorylates the serine 14 residue on glycogen phosphorylase b, thereby activating it.
In summary, phosphorylation by phosphorylase kinase is critical for the regulation of glycogen metabolism, especially during the breakdown of glycogen to produce glucose for the energy needs of the cell. This regulation is tightly coupled to the cell's metabolic state and responds to hormonal signals reflecting the organism's overall energy balance.

Nijmegen breakage syndrome is a human disease that is characterized by immunodeficiency, cancer predisposition, and microcephaly. It is a disorder that is caused by the inheritance of two mutant copies of a gene called NBS1, whose product is involved in DNA repair. Knowing this, what does this tell you about the relationship between DNA repair processes and the immune system?
A. DNA repair processes must be critical for the proper functioning of the immune system, as when they are nonfunctional, the immune system does not function properly.
B. The NBS1 gene must have multiple alleles, one that affects DNA repair, and one that affects the immune system.
C. Nijmegen breakage syndrome is caused by an epistasis relationship between a gene affecting DNA repair and a gene affecting the immune system.
D. Nothing. Nijmegen breakage syndrome is the result of polygenic inheritance, and therefore the immunodeficiency seen in these patients is due to the inheritance of another gene.
Answer:
A. DNA repair processes must be critical for the proper functioning of the immune system, as when they are nonfunctional, the immune system does not function properly.
Explanation:
The Nijmegen breakage syndrome (NBS) affects the immune system and this disorder is produced by mutations in the NBS1 gene involved in DNA repair, thereby evidencing a causal relationship between the immune system and the mechanism of DNA repair
Which of the following statements about actin is correct?
a. If the actual amount of available ATP-bound G-actin is below the critical concentration at both ends of a filament, then the actin filament will depolymerize.
b. Actin monomers are called G-actin because they have a nucleotide binding site that accommodates a molecule of GTP.
c. The plus end of an actin monomer has a net positive charge.
d. Actin generally polymerizes more rapidly at the pointed end.
e. Polymerization of an actin filament will only occur at the plus end.
Answer:
Option C
Explanation:
The G actin are Actin monomers have a nucleotide binding site which accommodates a molecule of ATP where ATP is hydrolyzed after polymerization. The plus end of an actin monomer has a net positive charge. Polymerization of an actin filament occur at the both ends but elongation is faster to about 4-5 times at the plus end than at the minus end. Actin generally polymerizes more rapidly at the barbed end than the pointed end.
Answer:
The correct answer is option a. "If the actual amount of available ATP-bound G-actin is below the critical concentration at both ends of a filament, then the actin filament will depolymerize".
Explanation:
Actin is the monomeric subunit of most filaments in cells, constituting the the cytoskeleton that brings support and maintains the cells' structure. Actin filament depolymerization is a process that allows for the creation of turnovers in the cytoskeleton and ensures that enough actin subunits are available to produce the filaments. One signal that starts actin filament depolymerization occurs when the actual amount of available ATP-bound G-actin is below the critical concentration at both ends of a filament. This occurs in the opposite direction as well, because the ability of a solution of G-actin to polymerize is given when the available ATP-bound G-actin is above the critical concentration.
