The correct option is (b) The Y chromosome carrying the SRY gene.

Conception refers to the period when a sperm cell from a male and an egg cell from a female fuse together to create a zygote. This is known as fertilization.

When the sperm and egg combine, they create a zygote, which is a single cell that contains all of the genetic material required to produce a new individual.

The XY sex chromosomes in humans are the chromosomes that decide the male sex. When fertilization occurs, the mother always provides an X chromosome, while the father contributes either an X or a Y chromosome.

If the father contributes an X chromosome, the zygote will develop into a female, while if the father contributes a Y chromosome, the zygote will develop into a male.

The Y chromosome carries the SRY gene, which controls the growth of testes in males. The Y chromosome is not bigger than the X chromosome, but the X chromosome has a lot more genetic material than the Y chromosome.

The metabolic rate and prenatal development of zygotes with XY chromosomes are not impacted by their sex chromosomes.

The most likely factor to increase in garter snakes is the frequency of the variant gene in the population. Here option C is the correct answer.

Garter snakes are known to be highly adaptable and can evolve rapidly to tolerate or resist toxins from their prey. This adaptation is usually driven by natural selection, which favors individuals with traits that provide a survival advantage in their environment.

If a variant gene that provides toxin resistance arises in a garter snake population, and this trait confers a survival advantage in their environment, then the frequency of this gene will increase over time through natural selection. The garter snakes that possess the variant gene will be better adapted to their environment and more likely to survive and reproduce, passing on the variant gene to their offspring.

Therefore, the frequency of the variant gene is the most important factor in determining the evolution of toxin resistance in garter snakes. The other factors listed, such as the number of genes in the population or the rate of gene replication or mutation, may also play a role in evolution, but their effect on adaptation to toxins is likely to be indirect.

When bacterial DNA is exposed to UV radiation, it can lead to the formation of thymine dimers, which are covalent bonds that form between adjacent thymine bases in the DNA strand.

These dimers cause the DNA to become distorted, leading to errors in DNA replication and transcription. The distortion caused by thymine dimers can prevent DNA polymerases and other enzymes involved in DNA replication and transcription from accurately copying the genetic code. This can lead to mutations in the DNA sequence, which can disrupt the normal function of the bacterial cell.

In some cases, the mutations may be lethal to the bacterial cell because they can affect essential cellular processes, such as DNA repair or protein synthesis. The mutations may also interfere with the normal functioning of bacterial enzymes, causing metabolic dysfunction and cellular damage. As a result, the bacterial cell may become unable to survive, replicate, or perform its normal functions, leading to cell death.

Photosynthesis and respiration are almost symmetrical processes, as both involve the conversion of energy between different forms. During photosynthesis, light energy is converted into chemical energy in the form of glucose, while during respiration, glucose is broken down to release energy that is used to produce ATP.

However, while the overall process of converting sugar back into ATP is exergonic (releases energy), there is still some energy lost in the form of heat. This is because not all of the energy released during the breakdown of glucose can be captured and converted into ATP.

Some of the energy is lost during the conversion process itself, as well as through various metabolic reactions that occur throughout the cell. Therefore, while photosynthesis and respiration are symmetrical in terms of the overall conversion of energy, there is still some energy loss during the process of converting sugar back into ATP.

The reactants of glycolysis are glucose, NAD⁺, ATP. Option A, B, and C is correct.

Glycolysis is the metabolic pathway which converts glucose into pyruvate. It is an important process in cellular respiration, which is the process by which cells generate energy from glucose and other nutrients. Glycolysis takes place in the cytoplasm of cells and consists of a series of 10 chemical reactions, which can be grouped into two stages: the energy investment phase and the energy payoff phase.

During the energy investment phase, two ATP molecules are used to phosphorylate glucose, which makes it easier to break down in the subsequent steps. The glucose molecule is then split into two three-carbon molecules called glyceraldehyde 3-phosphate (G₃P).

In the energy payoff phase, the G₃P molecules are converted into pyruvate through a series of reactions that generate four ATP molecules and two NADH molecules. The ATP molecules are produced through a process called substrate-level phosphorylation, in which a phosphate group is transferred from a molecule to ADP, forming ATP. The NADH molecules are produced by the transfer of electrons from G₃P to NAD⁺.

The lysing or lysis of a cell refers to the process of breaking down and rupturing the cell membrane, which results in the release of the cellular contents.

This process can occur in different phases of a cell's life cycle, depending on the circumstances.

For example, in the context of bacterial growth, the lysis of a cell can occur during the late stage of the lytic cycle of bacteriophages, which are viruses that infect bacteria. During this phase, the bacteriophage causes the host cell to produce and assemble new virus particles, which eventually lead to the lysis of the cell, releasing the new viruses to infect other cells.

In other cases, the lysis of a cell may occur as a result of physical or chemical damage to the cell membrane, such as exposure to toxins or extreme changes in temperature or pressure. In these cases, the lysis may occur at any phase of the cell's life cycle, depending on when the damage occurs.

Therefore, the lysing of a cell does not occur in a specific phase of a cell's life cycle, but rather is a process that can occur at various stages under different circumstances.
