OPtions are not provided in the question, The complete question is:

Some photosynthetic organisms contain chloroplasts that lack photosystem II, yet are able to survive. The best way to detect the lack of photosystem II in these organisms would be

A) to determine if they have thylakoids in the chloroplasts.

B) to test for liberation of O2 in the light.

C) to test for CO2 fixation in the dark.

D) to do experiments to generate an action spectrum.

E) to test for production of either sucrose or starch.

Answer: B) Test for liberation of O2 in the light.

Explanation:

Photosystem II is the first protein complex in the light-dependent oxygen photosynthesis reactions. It is found within algae, plant and cyanobacteria thylakoid membrane.

Enzymes absorb photons of light inside the photosystem to energise electrons, which are then transferred to plastoquinol through a combination of coenzymes and cofactors to minimise plastoquinone.

A test can be perform to liberate the oxygen (O2) in the light which is trapped in thylakoid membrane, if the light is liberated it shows presence of photosystem II and if no light will liberate, it shows lack of photosytem II.

Hence, the correct option is B.

The lack of Photosystem II in photosynthetic organisms can be detected by measuring the production of oxygen during photosynthesis.

The best way to detect the lack of Photosystem II in photosynthetic organisms is through experiments that measure the production of oxygen during photosynthesis. Photosystem II is responsible for splitting water molecules and releasing oxygen as a byproduct. Therefore, if an organism lacks Photosystem II, it will not produce oxygen during photosynthesis. One way to measure oxygen production is through the use of a dissolved oxygen probe, which can monitor the change in oxygen concentration over time.

Explanation:

Answer:

Yes,  P. Falciparum and T. Cruzi undergo similar antigenic variation because of repetitive genomes evolved by time.

Explanation:

Living (i.e., actively proliferating) repeats are dynamic elements which reshape their host genomes by generating rearrangements, creating and destroying genes, shuffling existing genes, and modulating patterns of expression. Dead repeats (i.e., those which are no longer able to proliferate) constitute a palaeontological record, which can be mined for clues about evolutionary events and impetus. The dynamic nature of repeats leads to a rapid evolutionary divergence that can be used in species identification and phylogenetic inference. Repeats can also provide passive markers for studying processes of mutation and selection.

The genomes of these protozoan parasites, like all eukaryotic genomes, have been colonized by diverse repetitive elements. Repetitive sequences can be artificially divided into two groups: interspersed repeats and tandemly repeated DNA. P. falciparum undergoes antigenic variation ans similar anitgenic variation is present in t. cruzi because of repetitive sequences resembling each other.

P. Falciparum and T. Cruzi do undergo similar antigenic variation.

P. Falciparum and T. Cruzi do undergo similar antigenic variation. Antigenic variation refers to the ability of a pathogen to change its surface proteins in order to evade the immune system. Both P. Falciparum and T. Cruzi are parasitic pathogens that infect humans and undergo antigenic variation. For example, P. Falciparum causes malaria by infecting red blood cells, and it is known to switch the expression of its surface proteins, such as the var genes. T. Cruzi, the causative agent of Chagas disease, also exhibits antigenic variation through the expression of different surface proteins called mucins.

Answer:

Answered below.

Explanation:

The nerve fibres of the autonomic nervous system that connects the ganglia to the the central nervous system are called preganglionic fibres. They are divided into sympathetic preganglionic fibres and parasympathetic preganglionic fibres and both have acetylcholine as their neurotransmitter.

The sympathetic preganglionic is shorter compared to the parasympathetic preganglionic fibres. They originate from the hypothalamus and brainstem and project to the ganglia non the spinal cord. A ganglion is a cluster of nerves outside the central nervous system.

The preganglionic sympathetic fibres originating from T1-T2 innervate the cervical ganglion which innervates the muscles of the pupils (dilators).

The postganglionic fibres originating from the preganglionic fibres of T11-L3 passes through splenic, celiac and mesenteric ganglia to innervate the kidneys and renal vessels.

Answer:

Proximal tubules.

Explanation:

The proximal tubules make up a significant portion of the kidneys and they are also the site of active solute secretion, hormone production, and many of the metabolic functions of the kidney. This segment of the nephron in kidney has two main functions: absortion and secretion. A hundread percent of organic solutes, such as glucose and amino acids are reabsorbed, that's why they should not be present in his urine.

Answer: d. none of the other answers

Explanation:

Enzymes that turn chemical energy into mechanical work are molecular motors.

There are three main components of cytoskeleton including microtubules, actin filaments and Intermediate filaments. Only actin  filaments and microtubules carry the motor-driven transport on the cytoskeleton.

The most important feature of intermediate filaments is to provide the plasma membrane with mechanical support where it comes into contact with the extracellular matrix and other cells.

Unlike microtubules and microfilament , intermediate filaments are not involved in motility of the cells, hence do not associat with molecular motors.

Answer: The options are missing from the question.

A) Na+ is bound

B) ADP is bound

C) The pump is phosphorylated

D) The pump changes conformation

The correct answer to the question is option C

THE PUMP IS PHOSPHORYLATED

Explanation: Sodium potassium pump (Na+ K+ pump) is a mechanism that uses active transport to move sodium Na+ and potassium K+ in and out of cellular compartments (intracellular and extracellular) inorder to maintain a gradient. It is responsible for maintaning a high extracellular sodium ion concentration and a high intracellular potassium ion concentration.

Once the sodium-potassium pump hydrolyses ATP,the pump will become phosphorylated (transmission of signal throughout the cell) lowing the affinity of the pump to sodium,this causes 3 sodium ions to move out of the intracellular compartment into the the extracellular compartment. The pump further brings two potassium ions together causing a dephosphorylation(inhibition of signal transmission throughout the cell) and then moves the 2 potassium ions out of the cell. This mechanism continues till there is a higher extracellular sodium concentration and a high intracellular potassium concentration therefore achieving the desired gradient(optimum)

Answer:

According to Irvin D. Yalom, we find it difficult to make a decision for fear of making a mistake with what we choose, for feelings of guilt and remorse for what could happen, and for the anxiety that comes with taking the action.

Explanation:

According to data obtained by Dr. William Newsome, decisions are made by a neuronal group located in the frontal lobe that is responsible for integrating the information and then making a single decision.

This means that to make a decision, all the details of the decisions to be taken must be taken into account so that the frontal lobe decides which of these characteristics could release more endorphins knowing that the person made a good decision.

Answer:

Explanation:

Today people suffer more for indecisive mind and there are many causes behind it:

People are busier and they have narrow world. So, they do not have reliable friend to discuss before taking decision. They have lack of knowledge to the reality. They fail to understand what a reasonable way for taking decision is.

Now people are so isolated that they suffer from depression, anxiety, worries and so on. Such demerits of the mind prevent one to take right decision.

Now most of the people, especially in the young generation, have little control over their emotion. They have least patience, and self control. Naturally they cannot take decision.

Neuroticism or emotional instability causes bar for taking decision.

The main psychological facts that cause indecision are phobic reaction, anger, depression, paranoid thoughts and so on. They have great effect in the brain. The stimulation of the brain works haphazardly. It needs counselling. Mainly the students and young generation suffer from this type of deformities in the brains. Various psychiatric clinics also establish these views.

Answer:

C) Hummingbirds promoted speciation less than did bees

Explanation:

The correct conclusion that can be drawn from the data is that hummingbirds promoted speciation less than did bees.

Speciation is defined as the appearance of new species in an environment and it is directly proportional to the number of species.

Hence, the higher the number of species found under each pollination category, the higher the speciation.

In this case, more species were found under the bee pollinated category compared to the hummingbird pollinated category. It thus means that the bees promoted speciation more than the hummingbirds.

The correct option is C.

Answer:

C) Hummingbirds promoted speciation less than did bees.

Explanation:

It is possible that honey bee pollination' conducted at higher rates of speciation in the angiosperms. However, it is important to note that the C) statement is just a hypothesis and further experiments should be carried out to confirm the role of bees in the speciation of this group

Answer: C. Patent ductus arteriosis

Explanation:

Patent ductus arteriosis is a physiological condition in which the ductus arteriosus does not close after birth. This results in the flow of the oxygenated blood from the left heart to flow back to the lungs by passing through the aorta.

The blood in the aorta is at high pressure. This results in continuous murmur due to the generation of the constant pressure gradient in the diastole and the systole, that forces the blood from the aorta to the pulmonary artery. The murmur sound is louder in the systole than in diastole.

Based upon the above explanation, Patent ductus arteriosis is the condition that is responsible for the murmur.

Answer:

Artificial selection

Explanation:

The process is an example of artificial selection.

Artificial selection is process in which members of a population with desired features/characteristics are deliberately favored to reproduce within the population.

The process which is also referred to as selective breeding is used by man to selectively develop particular phenotypic traits in farm animals.

In this case, the desired traits are increased milk production and larger muscle size and these two traits co-occurred with having smaller brain and larger eyes. Hence, the latter traits are selected for in order to get the desired traits.

Final answer:

The observed traits in domesticated cows are the result of artificial selection, where humans selectively bred animals to enhance certain characteristics like milk production and muscle size, demonstrating both artificial selection and biocultural coevolution.

Explanation:

The traits observed in the domesticated cow Bos primigenius, such as a smaller brain, larger eyes, increased milk production, and larger muscle size, are the result of artificial selection. This process involves humans selectively breeding animals or plants to produce specific traits. Farmers selected for traits that were beneficial to them, like more milk and muscle, which over generations led to the domesticated cows we see today. This process intensified the human-animal relationship, as early herders realized they could benefit from live animals for products like milk, rather than just meat.

Moreover, the phenomenon of biocultural coevolution illustrates the interplay between the biology of human populations and their cultural practices of domestication. As farmers bred animals with desirable qualities, their own genetic predispositions, such as lactose tolerance, also evolved to optimize the use of those domesticated animals.

In summary, the selective breeding carried out by farmers which led to traits like increased milk production and larger muscle size in domesticated cows is an example of artificial selection, a cornerstone of both past and present agricultural practices.

Answer:

Cows that produce lots of milk,Chickens that produce large eggs,Wheat plants that produce lots of grain.

More grains being grown is helpful since it contains things that the human body needs to survive.

Explanation:

Selective breeding in crops and domestic animals has led to significant improvements in agricultural productivity. Example include breeding cows for higher milk quality, creating new dog breeds through artificial breeding, and genetically engineering crops with specific traits. Breeders can select for a particular trait by choosing individuals that already possess the trait and breeding them together.

Selective breeding is used to improve crops and domestic animals. Three examples of selective breeding are:

To select for a particular trait, breeders can choose individuals that already possess the desired trait and breed them together. This increases the chances of offspring inheriting and expressing the desired trait. Over time, continuous selection for the trait can lead to significant improvements.

Explanation:

Many scientists and environmentalists blame the deforestation spike on President Jair Bolsonaro's aggressive policies to support mining and ranching and to dismantle environmental protections.

Brazil's President Jair Bolsonaro is allowing the destruction of the rainforest for a variety of reasons, including:


1. Economic development: Bolsonaro has argued that the Amazon rainforest should be exploited for its natural resources, including timber, minerals, and agricultural land, in order to boost Brazil's economy. This has led to an increase in deforestation, as trees are cut down to make way for farms, mines, and other development projects.


2. Support from powerful interest groups: Bolsonaro has received support from powerful interest groups, including agribusiness, mining, and logging companies, who stand to benefit from the destruction of the rainforest. These groups have lobbied for policies that allow for more deforestation, and Bolsonaro has responded by loosening environmental regulations and cutting funding for conservation efforts.


3. Personal beliefs: Bolsonaro has expressed skepticism about climate change and the importance of protecting the environment, and has criticized environmentalists and indigenous groups who seek to protect the rainforest. He has also argued that Brazil should have sovereignty over its own natural resources, and should not be subject to international pressure to protect the Amazon.


Overall, Bolsonaro's policies and actions have contributed to an increase in deforestation and destruction of the Amazon rainforest, which has sparked widespread criticism and concern from environmentalists, indigenous groups, and the international community.

Explanation:

Linda Thomas was diagnosed with an insulinoma, a benign tumor of the pancreas that secretes excess insulin, causing hypoglycemia. Unlike Type I diabetes, which leads to high blood sugar levels (hyperglycemia), an insulinoma causes low blood sugar levels (hypoglycemia). Both conditions affect blood sugar levels in opposite ways.

Linda Thomas was diagnosed as having a benign tumor of the pancreas that causes hypoglycemia by secreting insulin. This type of tumor is known as an insulinoma, which is a condition where the tumor cells produce an excess amount of insulin, leading to lower blood sugar levels. Hypoglycemia is the medical term for having lower than normal blood sugar levels. Unlike Type I diabetes, which is characterized by the pancreas's failure to produce insulin, leading to hyperglycemia (high blood sugar levels), an insulinoma causes the opposite effect, the lowering of blood sugar levels (hypoglycemia).

Type I diabetes and pancreatic tumors (such as insulinomas) have opposite effects on the body's blood sugar levels. While Type I diabetes results in high blood sugar levels due to insufficient insulin production, insulinoma results in low blood sugar levels due to excess insulin production.

Answer:

Option-D

Explanation:

Plasmodesmata are the plasma membrane lined pores present in the cells of the plants. Inside these pores runs a closed tubelike structure which is an extension of the endoplasmic reticulum.

The plasmodesmata allows cell to cell communication which involves symplast mode of transport that is through its cytoplasm.

The small water soluble molecules like amino acid and sugars can easily pass through these plasmodesmata via diffusion. The large molecules can be transported through these plamodesmata through selective diffusion.

Thus, Option-D is the correct answer.

An explanation of how plant cells communicate across cell walls will most likely refer to the diffusion through plasmodesmata is Small, water-soluble molecules.

Small water soluble molecules often cross the membrane through the process of Diffusion. It is known as passive transport due to the fact that no external energy is used.

Polar molecules, such as water and small water-soluble molecules example urea, chloride ions, sodium ions etc. often

diffuse across membranes through the water-filled channels formed by membrane proteins.

Plasmodesmata are refered to ad connections through which cells communicate chemically with one another via their thick walls.

Answer:

-Genotypes: 25% TT, 50% Tt, 25% tt.

-Phenotypes: 75% have the trait for tongue curling, the other 25% do not have the trait for tongue curling.

-Percentage change of each type: 25% TT (homozygous dominant), 50% Tt (heterozygous), and 25% tt (homozygous recessive).

Explanation:

So to calculate the probably of off spring, we usually make a Punnett square.

Since a Tt man marries a Tt woman, they produce "offspring" (babies) that look like this in a Punnett square:

TT Tt

Tt tt

Looking from this Punnett square, we have one that is TT, two that are Tt, and one that is tt, a total of four. Your genotypes are the genetical traits, so out of the four, you take a percentage and calculate the genes: 25% TT, 50% Tt, and 25% tt. Your phenotypes are your physical traits, so 75% will have the "tongue-curling" trait as the trait T is dominant in three of them (TT, Tt, and Tt), and the other 25% will NOT have the trait.

If both parents are Tt, then both types of offspring will be produced, one with the trait of tongue curling and another without it. 75% will be dominant, and 25% will be non-tongue curlers.

A monohybrid cross involves a trait such as tongue curling. This gene has two variations, one of which is for tongue curling and is dominant over the other. Another form is recessive and forms a non-curling type of tongue.

The curling gene is completely dominant over others and can express in both TT and Tt conditions. tt only expresses the recessive type, which is a non-curling tongue.

Here, both parents are Tt. So two types of offspring will be formed. TT will be 25%, Tt will be 50%, and the rest 25% is tt. Three of the four offspring are dominant, while one is recessive. The punnett square is explained below in the image.

Hence, from a heterozygous parent cross,75% will be dominant, and 25% will be non-tongue curlers.

Following the Mendelian genetics inheritance, ALL the offspring resulting from the cross between GGWw x ggww would have Green and wrinkled phenotype (100%). The restriction enzyme question cannot be answered due to the lack of provided gel image.

When cross-breeding occurs between organisms with the genotype GGWw and ggww, it's important to understand the results are influenced by the principles of Mendelian genetics where 'G' is dominant, representing yellow peapod colour and 'g' is recessive, representing green peapod colour. Similarly for seeds, 'W' symbolizes round (dominant) and 'w' for wrinkled (recessive).

The offspring from this mating will have a 100% probability of possessing the green peapod and wrinkled seeds phenotype. This is because the 'gg' genotype (green) from the second parent will only display green as it's recessive and the presence of even one 'w' allele (wrinkled) from either parent would result in wrinkled seeds - a distinctive feature of incomplete dominance. Hence, options 'A' through 'G', the correct answer for the phenotype contributions is 'G. 100% - Green and wrinkled'.

The second question about restriction enzyme cannot be properly answered because the gel image is not provided. The distinction between the wells is usually determined by the number of cut sites or the pattern of bands in the gel.
