Answer:

C

Explanation:

When an infection is caused the body usually responds in several ways, one way being fever hence flu's and colds

A. Repair systems that target a single type of damage in DNA and repair only that type of damage are called specific repair systems.

B. Repair systems that use a single repair mechanism to repair multiple types of damage in DNA are called nonspecific repair systems.

C. A system that only repairs thymine dimers is photo repair.

D. In excision repair, the damaged section of one DNA strand is removed and replaced with new DNA that is synthesized using the undamaged strand as a template.

E. Cells can repair the damage that produces breaks in DNA using enzymes related to those involved in recombination during meiosis.

Specific repair systems target and repair a single type of DNA damage, such as photo repair which repairs only thymine dimers caused by UV light. In contrast, general repair systems use a single mechanism to repair multiple types of DNA damage, such as excision repair which can repair damage caused by chemical exposure and radiation.

Photorepair is a specific repair system that repairs thymine dimers in DNA caused by UV light. The process involves using energy from visible light to break the bonds between the thymine molecules and return them to their normal state. Excision repair is a general repair system that involves removing a damaged section of DNA and synthesizing a new, undamaged strand using the complementary strand as a template.

Cells can also repair the damage that produces breaks in DNA using enzymes related to those involved in recombination during meiosis. This process, known as homologous recombination, involves exchanging genetic material between two homologous chromosomes to repair a break. This mechanism is highly regulated to prevent errors and ensure proper repair of DNA damage.

Depending on the environment, a spadefoot toad tadpole will develop one of two different body shapes. This is called Polyphenism.

Polyphenism is the phenomenon where two or more distinct phenotypes are produced by the same genotype. Examples of polyphenism provide some of the most compelling systems for the study of epigenetics.

The Eastern spadefoot belongs to the genus Scaphiopus, which differs from true toads in having vertical pupils, relatively smooth skin, and a distinct spade-like projection on the hind limbs from which its common name is derived. This spade-like projection is used in the excavation of burrows

Often called spadefoot toads, spadefoots are not true toads, nor are they true frogs, either. They're named for a feature on the inner surface of their hind feet, a spadelike spur that helps them to dig their burrows.

In mature red blood cells, also known as erythrocytes, energy is obtained exclusively by anaerobic respiration, which involves the breakdown of glucose in the cytoplasm. This process is known as glycolysis and does not require oxygen. The end product of glycolysis is ATP, which is the main source of energy for the cell. Since mature red blood cells lack mitochondria, they are not able to carry out oxidative phosphorylation, the process by which cells generate energy in the presence of oxygen. Therefore, they rely solely on anaerobic metabolism to produce ATP.

The yellow F2 genotypes result from a dihybrid cross between two pure-breeding parental strains of grape plants: green (wild-type) and yellow. The F1 generation, having all green grapes, indicates that green is the dominant trait while yellow is the recessive trait. In order to obtain the 9 green: 7 yellow ratio in the F2 generation, both F1 parents must be heterozygous for two different genes that contribute to grape color.

Let's denote the genes as "A" and "B", with "a" and "b" being the recessive alleles. The F1 parents have the genotype AaBb, which results from the cross between the parental strains (AABB x aabb). When two F1 plants (AaBb) are crossed, we obtain the F2 generation.

To determine the genotypes of the yellow F2 plants, we can use a Punnett square or apply the product rule for dihybrid crosses. The possible genotypes for yellow grapes must have at least one recessive allele for each gene (i.e., "a" and "b"). The yellow F2 genotypes are:

1. aabb: Both genes are homozygous recessive.

2. Aabb: Gene A is heterozygous, and gene B is homozygous recessive.

3. aaBb: Gene A is homozygous recessive, and gene B is heterozygous.

4. AaBb: Both genes are heterozygous.

These genotypes result in a phenotypic ratio of 9 green: 7 yellow in the F2 generation.

Fertilization is the process by which the male and female gametes (reproductive cells) combine to form a zygote, which develops into an embryo. In plants, fertilization refers specifically to the fusion of the male and female gametes of the flower, resulting in the formation of a seed.

In plants, the male gamete is produced by the pollen grain, which contains two sperm cells, while the female gamete is produced by the ovule, which is located in the ovary of the flower.

When a pollen grain lands on the stigma (the receptive surface of the female reproductive organ), it germinates and sends out a pollen tube that grows down the style and reaches the ovary. One of the sperm cells is then released and fuses with the egg cell inside the ovule, forming a zygote.

The other sperm cell fuses with two polar nuclei to form a triploid cell, which develops into the endosperm, a nutrient-rich tissue that provides nourishment to the developing embryo.

During moderate exercise in the heat, the vascular beds that receive the most blood flow are option c. muscle and skin. This is because during exercise, the muscles require an increased amount of oxygen and nutrients to support their activity. As a result, the blood flow to the muscles increases to provide them with the necessary resources.

Similarly, the skin also receives an increased amount of blood flow during exercise in the heat. This is because the body needs to regulate its temperature by dissipating heat through the skin. Increased blood flow to the skin allows for more efficient heat dissipation, which helps to prevent overheating and maintain optimal body temperature.

On the other hand, the splanchnic and renal vascular beds receive less blood flow during exercise in the heat. This is because during exercise, blood is redirected away from these areas to the working muscles and skin. While the kidneys still require a certain amount of blood flow to maintain their function, the splanchnic area, which includes the gut, can experience reduced blood flow during exercise. This can lead to gastrointestinal discomfort or even injury in extreme cases.
