What are the metabolic waste products produced when animal cells use each of the macromolecules (carbohydrates, proteins, lipids) in aerobic respiration? Related to this question, why are fishes able to extract more energy from proteins than mammals or birds? Please be specific in your responses!

Answers

Answer 1

Answer:

Metabolic stuff made once animal cells use carbohydrates are greenhouse gas and H2O, lipids - greenhouse gas and H2O, macro-molecule - carbamide and acid. Fish would like macro-molecule principally for growth. Fish eat to satisfy their energy demands. if the energy state of diet is a smaller amount, they waste macro-molecule to fulfill the metabolic desires, if energy state is high, it'll cut back the intake of food.

Although in reality the inheritance of cleft chin (e.g., the deep chin dimple seen in Ben Affleck) is slightly more complicated, for now let's assume that the presence or absence of a cleft chin is determined by one gene. By studying pedigrees, we know that no child possesses a cleft chin unless at least one parent does (either the mom or the dad). Hint: Based on that last statement, you should now know the mode of inheritance! What is it? (Remember Recessive traits can hide, but dominant traits never do!) (1) Cleft chin is a dominant trait. (2) Cleft chin is a recessive trait.

Answers

Answer:

Cleft chin is a dominant trait

Explanation:

Single gene inheritance: From the description, cleft chin is a dominant trait if at least one parent has it. For a trait to be inherited in the recessive condition, both parents must have a copy each of that trait. But for this trait to be inherited from at least one parent, it has to be a dominant trait.

Final answer:

Cleft chin is a dominant trait; a child will not exhibit it unless at least one parent also has a cleft chin. Offspring have a 50% chance of having a cleft chin if one parent is heterozygous for the trait and the other parent does not have a cleft chin.

Explanation:

The trait in question, a cleft chin, is determined by one gene with two alleles. Given that a child will not have a cleft chin unless at least one parent has it, we can conclude that cleft chin is a dominant trait. This mode of inheritance indicates that if a parent has a cleft chin, they must have at least one dominant allele (B), which is expressed in the physical appearance, overriding the recessive allele (b) for a smooth chin.

If we assume the parent with a cleft chin is heterozygous (Bb), and the other parent has no cleft chin (therefore having two recessive alleles, bb), their offspring would have a 50% chance of inheriting the cleft chin. This is because the offspring can inherit either the dominant allele from the cleft-chinned parent, leading to a cleft chin (Bb), or inherit only recessive alleles from both parents, resulting in no cleft chin (bb).

Ben Affleck has a cleft chin, but his ex-wife Jennifer Garner does not. Neither one of their two daughters (Violet and Seraphina) has a cleft chin, but son Samuel does. Draw a pedigree for the Garner/Affleck family including the genotypes for all five individuals. Use your pedigree to answer the question: What are the genotypes of Ben, Jen, Violet, Seraphina, and Samuel?

Answers

Answer:

Ben - Y Xc

Jen - XCXC

Violet - XCXc

Seraphina - XCXc

Samuel- Y Xc

Explanation:

Given -

Ben has a cleft chin

Let the allele for cleft chin be "c"

and the allele for normal chin be "C"

When Ben with cleft chin mates with wife Jennifer Garner having normal chin, then the two girl child do not have cleft chin but the boy has cleft chin.

This means that the allele C could be X -linked and the mother is not the carrier but the father is

The genotype of father Ben would be Y Xc

Genotype of mother would be XCXC

Genotype of two daughters XCXc  , XCXc which means they are carrier for the next generation

Genotype of Boy - Y Xc

Pedigree for the Garner/Affleck family:

Ben (Cc)

    /     \

   Jen (cc)   Samuel (CC/Cc)

  /         \

Violet (cc)  Seraphina (cc).

Genotypes of all five individuals:

Ben Affleck: Cc (heterozygous for a cleft chin)

Jennifer Garner: cc (homozygous recessive for no cleft chin)

Violet Affleck: cc (homozygous recessive for no cleft chin)

Seraphina Affleck: cc (homozygous recessive for no cleft chin)

Samuel Affleck: CC/Cc (heterozygous or homozygous dominant for a cleft chin)

We can also determine the genotypes of Violet, Seraphina, and Samuel based on the pedigree. Since Jennifer Garner is homozygous recessive for no cleft chin (cc), she can only pass on the recessive allele to her children.

Therefore, Violet and Seraphina must also be homozygous recessive for no cleft chin (cc).

Samuel Affleck is the only child in the family who has a cleft chin. This means that he must have inherited at least one copy of the dominant allele for a cleft chin from his father, Ben.

Therefore, Samuel must be either heterozygous (Cc) or homozygous dominant (CC) for a cleft chin.

we know that the most likely genotypes for all five individuals are as follows:

Ben Affleck: Cc

Jennifer Garner: cc

Violet Affleck: cc

Seraphina Affleck: cc

Most black bears (Ursus americanus) are black or brown in color. However, occasional white bears of this species appear in some populations along the coast of British Columbia. Kermit Ritland and his colleagues determined that white coat color in these bears results from a recessive mutation (G) caused by a single nucleotide replacement in which guanine substitutes for adenine at the melanocortin 1 receptor locus (mcr1), the same locus responsible for red hair in humans (K. Ritland, C. Newton, and H. D. Marshall. 2001. Current Biology 11:1468–1472). The wild-type allele at this locus (A) encodes black or brown color.

Based on morphological and molecular data, researchers hypothesize that the split between dugongs and proboscideans likely occurred between 48 and 34 million years ago. Explain how molecular data from fossils and living organisms would support the existence of an evolutionary relationship between dugongs and proboscideans.

Answers

Final answer:

Molecular data from both living organisms and fossils provide evidence to support an evolutionary relationship between dugongs and proboscideans. Analysis of such data helps to track shared genetic elements as well as evolutionary divergences. Beyond morphology, other evolutionary trends can be analyzed, such as the fossil record of the evolution of horses in North America.

Explanation:

Molecular data from both fossils and living organisms provide evidence supporting an evolutionary relationship between dugongs and proboscideans, which include elephants. Mitochondrial DNA, nuclear DNA, ribosomal RNA (rRNA), and specific cellular proteins from present organisms and fossilized remains can be analyzed to track shared genetic elements and evolutionary divergences.

In addition to morphological similarities found in fossils, other evolutionary trends can be analyzed. For instance, the fossil record of horses in North America shows an evolution of teeth shapes and foot and leg anatomy adapting to a changing environment over millions of years. This isn’t different from what researchers hypothesize occurred between the dugongs and proboscideans, given the estimated timeline of their divergence.

Such analyses lead to insights into the phylogenetics of these creatures. By looking at these records, scientists can build phylogenetic trees that map the proposed evolution of species, showing the divergence of the dugongs and proboscideans from a common ancestor.

Molecular data, such as DNA and protein sequences, along with molecular clocks, support the hypothesized evolutionary relationship between dugongs and proboscideans by identifying genetic similarities and estimated divergence times that match the morphological data.

Molecular data from fossils and living organisms support the evolutionary relationship between dugongs and proboscideans in several ways:

Comparing DNA sequences between living dugongs, fossils, and proboscideans can show similarities that suggest a common ancestor.Analyzing protein sequences can also reveal evolutionary relationships, where smaller differences between molecules indicate closer connections.Molecular clocks, which estimate the time since two species diverged based on genetic mutations, can align with the hypothesized split between dugongs and proboscideans.

These molecular methodologies, combined with morphological data, create a more complete evolutionary history, giving evidence to the shared lineage of seemingly disparate species.

In the Arrow/Midas Cichlid sympatric speciation hypothesis, the investigators had to investigate not only the biology and genetics of the species in question, but had to understand the geological history of the larger geological basin in which they occurred, AND the phylogeny of the populations. This is because Investigators had to eliminate allopatric speciation and utilize phylogenetic patterns to support or refute sympatric speciation.

Investigators needed to consider the geological history, biology, and phylogeny to fully understand the potential for sympatric speciation in cichlid fish. They had to eliminate allopatric speciation and subsequent dispersal as a hypothesis, because such events involve physical separation of populations, which is not the case in sympatric speciation. In addition, certain phylogenetic patterns could corroborate or reject the hypothesis of sympatric speciation by showing whether populations diverged in situ without geographic isolation.

7. ribosome reads a stop codon

8.polypeptide chain is released from the P site

9. ribosomal subunits dissociate

Explanation:

The translation is a process which translates the nitrogenous bases or codons in the proteins.

The process of translation requires the mRNA, tRNA and ribosome and proceeds in three stages: the initiation, elongation and the termination.

The process begins with the binding of the small subunit of the ribosome to the mRNA. The charged tRNA with a first amino acid called methionine binds the mRNA and scans the mRNA until it finds the start codon.  

After it finds the start codon, the large subunit complex binds the mRNA and form initiation complex. After this, the amino acid enters the P-site of the ribosome where elongation of peptide takes place.

The peptide then exits from the E-site and the ribosome dissociates.

Final answer:

Protein synthesis begins with the formation of an initiation complex involving the small ribosomal subunit, mRNA template, initiation factors, and initiator tRNA. The initiator tRNA has anticodon UAG and interacts with the start codon AUG, carrying the amino acid methionine.

Explanation:

Protein synthesis begins with the formation of an initiation complex. This complex involves the small ribosomal subunit, the mRNA template, initiation factors, and a special initiator tRNA, called tRNAMet. The initiator tRNA has anticodon UAG, which interacts with the start codon AUG and is charged with the amino acid methionine. Methionine is therefore the first amino acid of every polypeptide chain.

At the beginning of Unit 3 we saw the example of the pygmy seahorse, whose offspring can change their body color, depending on the color of the coral they settle on from orange to purple. This ability to change body color depends on a complex developmental response that involves numerous genes that code for regulatory proteins that can alter the developmental pathway of a developing baby seahorse. Identify which aspect of color determination is subject to natural selection. Whether baby sea horses have the ability to change their color depending on their environment ... Answer 1 Whether baby sea horses develop orange or purple body color ... Answer 2

Answers

Answer:

Seahorses are between the sea animals that may modification color. Such variations camouflage the creatures if not obscure or perhaps frighten possible predators. Color variations facilitate seahorse’s link emotions and intentions, particularly throughout suit. Whereas these alterations are stunning and infrequently seem seamless, they're truly the merchandise of complicated interactions between the seahorse's brain and small organs carried within its skin.

Anatomy

Seahorse organelles, known as chromatophores, are enclosed at intervals their skins. These tiny, sack like organs contain variety of pigments and may expand or consent response to a spread of stimuli, inflicting the seahorse to vary color. Typically, seahorses carry solely a couple of chromatophore diversities, so completely different colors are created through the blending and matching of accessible pigments.

Building Color

All of the colours to that a seahorse will modification are derived from 3 or four basic stains contained in several chromatophores. The pigment cells of those chromatophores are sometimes stacked on prime of every alternative or clustered along in teams. the colour a seahorse displays is predicated on sort, combination and attentiveness of those cells, moreover as their proximity to the skin's surface.

Brightness and Tone

Muscles hooked up to chromatophores will push stain cells toward, or pull coloring cells off from, the surface of a seahorse's skin. Once the coloring is on the point of the skin's surface, the animal's color is brighter and splendid. In turn, once the pigment attracts off from the skin's surface, the ensuing color is a smaller amount saturated and somewhat boring.

Speed of modification

Depending on the stimulant that causes a seahorse to vary its color, chromatophores are measured by the seahorse's system or by its secretion fluctuations. once the system activates chromatophores, comparable to in life-and-death things, the animal's color changes quickly. once chromatophores are activated by secretion fluctuations, comparable to once a seahorse is suit a mate, the animal's color in its place changes somewhat slowly.

Both of them aren't subjected to action because the color modification in ocean horse are influenced by system and secretion system.

Final answer:

The ability of seahorses to change color in response to their environment is an aspect of color determination subject to natural selection. This adaptability is genetically controlled and influenced by the environment, providing a survival advantage. This case is an example of a gene-environment interaction.

Explanation:

The aspect of color determination subject to natural selection in seahorses is the ability of their offspring to change their body color in response to their environment. This is a complex developmental response triggered by numerous genes. These genes code for regulatory proteins that can alter the developmental pathway, leading to different body colors in offspring. For example, if a baby seahorse settles on an orange coral, it may develop orange coloration; if it settles on a purple coral, it may develop purple coloration. This adaptive characteristic gives seahorses a survival advantage, making them more invisible to predators and more successful at catching prey. Thus, natural selection can favor seahorses with this trait.

However, it is crucial to note that color change in baby seahorses is not determined by the environment alone, but is under genetic control influenced by the surrounding environment. This is a case of gene-environment interaction.

A similar phenomenon can be observed in side-blotched lizards or other creatures like the peppered moths in England in the time of the Industrial Revolution. Their environment caused a shift in coloration to survive their changing habitats, leading to a shift in the population's genetic variance towards the new, fit phenotype. This adaptability is a wonderful example of how species can evolve through natural selection to increase their survival and reproductive success.

Explanation:

What:

Final answer:

In fish, blood and water flow in opposite directions in a countercurrent exchange system for efficient gas exchange. Blood flows through the gills picking up oxygen, then through the body, and the single circuit heart pumps deoxygenated blood back to the gills.

Explanation:

In the countercurrent exchange system of fish gills, blood and water flow in opposite directions to maximize gas exchange efficiency. The blood flows through the gills, passing over deoxygenated veins first, where it picks up oxygen from the water. This system, known as gill circulation, is unidirectional, with the oxygenated blood then flowing to the rest of the body. Unlike in mammals, fish have a single circuit for blood flow and a two-chambered heart, comprising only one atrium and one ventricle. The oxygenated blood flows past the organs and the rest of the body, delivering oxygen before returning to the heart, a process called systemic circulation. The large surface area of the gills, due to their folded structure, is paramount for this efficient gas exchange, where oxygen molecules diffuse from areas of high concentration in the water to low concentration in the blood.

The correct conclusion is that the mutant strain will not be viable under anaerobic conditions when glucose is the only energy source available.

In biochemistry, the viability of an organism, particularly a microorganism, is often linked to its ability to metabolize nutrients to produce energy. Aerobic respiration is a metabolic process by which cells use oxygen to convert glucose into energy. In contrast, anaerobic respiration is a process by which cells convert glucose into energy without the use of oxygen.

The information provided indicates that the mutant strain can grow aerobically, which means it can use oxygen to metabolize glucose or other substrates to produce energy. However, the mutant strain cannot grow on glucose anaerobically. This suggests that the mutant strain lacks the necessary biochemical pathways to metabolize glucose in the absence of oxygen.

In many organisms, particularly facultative anaerobes, the ability to switch between aerobic and anaerobic respiration is crucial for survival in environments where oxygen levels may fluctuate. For example, in the absence of oxygen, these organisms can ferment glucose to lactate or ethanol, or use alternative electron acceptors in anaerobic respiration.

If the mutant strain cannot grow anaerobically on glucose, it means that it cannot produce energy from glucose without oxygen. This would severely limit the mutant strain's viability in anaerobic environment where glucose is the primary or only available energy source. Therefore, the mutant strain would not be considered viable under those specific conditions, supporting the boss's assertion.

In summary, while the mutant strain can survive and grow in the presence of oxygen, its inability to metabolize glucose anaerobically would render it non-viable in anaerobic environments where glucose is the sole energy source. This conclusion is consistent with fundamental principles of microbial metabolism and the requirements for cellular energy production."

The human body works well when the cells of the body work well. The cells in the body work well when the
conditions are just "right." These "right" conditions are maintained by the body through
the state of maintaining a stable internal environment despite changing external conditions.

Answers

Answer:

That is correct...it can also be called homeostasis

Answer:

The human body works well when the cells of the body work well. The cells in the body work well when the conditions are just “right.” These “right” conditions are maintained by the body through homeostasis, the state of maintaining a stable internal environment despite changing external conditions.

Temperature , amount of sugar, and amount of water are some conditions that need to be right in the body for cells to work properly. When all the conditions are just right, the cells function properly.

True or false 100% of what you look like or behave like come directly from both of your parents?

Answers

Answer:

False.

Explanation:

The way you behave does not usually come from either of your parents, you chose how you act. And how you look can could from your dad, mom, both or sometimes other ancestors. So it definitely False.

Club foot is one of the most common congenital skeletal abnormalities, with a worldwide incidence of about 1 in 1000 births. Both genetic and nongenetic factors are thought to be responsible for club foot. C. A. Gurnett et al. (2008. American Journal of Human Genetics 83:616–622) identified a family in which club foot was inherited as an autosomal dominant trait with reduced penetrance. They discovered a mutation in the PITXI gene that caused club foot in this family. Through DNA testing, they determined that 11 people in the family carried the PITXI mutation, but only 8 of these people had club foot. What is the penetrance of PITXI mutation in this family? Please round to two decimal places (e.g. 0.01).

Answers

Answer:

Penetrance might be characterized as the part of the predetermined genotypes populace that shows the normal phenotype.  

Here, total number of genotypes (PITXI transformation observed) = 11  

Genuine influenced phenotypes = 8  

Penetrance =  (Watched number of club foot occasions) / (all out number of people with PITXI transformation)  

 Penetrance = 8/11

Penetrance = 0.72

What is the function of these organelles

Answers

Answer:

Explanation:

Endoplasmic reticulum is the organelle that produces, processes and transport protein and lipids.

Golgi body is also referred to as the cell's post office. It modifies, packages and sorts protein for secreation.

Mitochondrion is referred to as the power house. It generates energy in form of ATP ( Adenosine triphospate).

Ribosome is the organelle that produces and synthesizes protein.

Cellular organelles, such as mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, peroxisomes, ribosomes, and the nucleus, perform distinct functions essential for cell vitality, like energy production, protein synthesis, and genetic information storage.

Organelles are specialized structures within cells that perform distinct metabolic functions, analogous to the organs in a human body. Cells contain various organelles that work in harmony to support the cell's life processes.

Mitochondria are known as the cell's 'powerhouses.' They generate the cell's energy in the form of adenosine triphosphate (ATP).The endoplasmic reticulum (ER) comes in two forms: rough ER, with ribosomes for protein synthesis, and smooth ER, for lipid synthesis and detoxification.The Golgi apparatus modifies, sorts, and packages proteins and lipids for distribution.Lysosomes are involved in digesting macromolecules and recycling cellular components.Peroxisomes break down fatty acids and detoxify harmful substances.Ribosomes are the sites of protein synthesis.The nucleus contains DNA and RNA, governing the hereditary characteristics of the cell and controlling cell activities.

Each of these organelles plays a critical role in maintaining the health and functionality of the cell, with specific structures that facilitate their specialized functions.
