Explanation:

Plant cells are different from the animal cells in their basic structure such as the cell wall which is absent in the animal cell, chloroplast is also found in the plant cell which is not present in animal cell.

Plant cells have a rigid cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a layer which is present outside the cell membrane and surrounds the cell, it provides the structural support and protection.

The central vacuole is present in the plant cell and it maintains turgor pressure against the cell wall. The central vacuole is a large vacuole found inside of plant cells. It is a sphere which is filled with fluid and molecules inside a cell. The central vacuole stores water.

Chloroplasts are the organelles which are responsible for the process of  photosynthesis, are in many respects similar to mitochondria. Both the organelles including chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, and also contain their own genetic systems, and replicate by division.

Starch is digested more rapidly than cellulose because of its branched polysaccharide structure.

Starch and cellulose are both polysaccharides made up of glucose molecules.

However, the difference in their structures affects their digestibility.

Starch is made up of both linear and branched chains of glucose molecules, while cellulose is made up of linear chains that are connected by hydrogen bonds to form a rigid and stable structure.

This branched structure of starch makes it easier for digestive enzymes to break down the bonds between glucose molecules, resulting in faster digestion.

This branched structure of starch makes it easier for digestive enzymes to break down the bonds between glucose molecules, resulting in faster digestion

Summary: Starch, with its branched polysaccharide structure, is digested more rapidly than cellulose due to its easier breakdown by digestive enzymes.

Matured fresh eggs of catfish serve as the primary reproductive cells, capable of fertilization. They provide the genetic material necessary for the development of catfish offspring. These eggs are typically laid and incubated in a suitable aquatic environment until they hatch, ensuring the continuation of the catfish species.

Fertilization is the biological process by which the male and female reproductive cells, sperm and egg respectively, combine to initiate the development of a new organism. It typically occurs internally in most animals, including humans. During sexual reproduction, the sperm is introduced into the female reproductive system, where it travels to meet the egg.

The sperm then penetrates the egg, resulting in the fusion of their genetic material. This fusion forms a zygote, which is the initial stage of the new organism. Fertilization is a crucial step that combines the genetic information from both parents, determining the traits and characteristics of the offspring. It kickstarts a series of developmental events that eventually lead to the formation of a fully functioning individual.

Oftentimes UV light can cause the genetic code of an organism to mutate, leading to a variety of errors, some of which are not compatible with life.

UV light is considered to be a mutagen. What this means is that the exposure of cells to UV light often leads directly to a mutation in the genetic code of that cell. This correlation has been studied extensively and shown to affect the nucleotides of DNA, which are:

The exposure to UV light causes the base nucleotides in the DNA of an organism to oxidize. This oxidization causes the base pairs to form dimers. Most often the dimer formed is of a thymine base. This can be thought of as the fusion between two thymine bases, which will alter the frame in which DNA is read and cause all sorts of abnormalities.

One similarity between lactic acid fermentation and alcoholic fermentation is that they are both types of anaerobic respiration, meaning they occur in the absence of oxygen.

One key difference is that lactic acid fermentation results in the production of lactic acid, while alcoholic fermentation results in the production of ethanol and carbon dioxide.

In ecology, density is a measure that refers to how many individuals a population has in a specific habitat.

Considering this, we can say that water is a density-dependent limiting factor, since this is a limited resource that can vary its availability annually, but also is a species have too many individuals, all of them will not have the same capacity to reach this resource, especially when we talk about large animals or plants.

Diseases caused by bacteria would be also a density-dependent limiting factor, since only when too many microorganisms of a pathogenic species replicate in our bodies, do we begin to feel the symptoms of that illness.

Predators are also a density-dependent limiting factor since the species which they feed on can be overhunted by them, being reduced in number of individuals, or being not too much hunted and increase their individuals.

Earthquakes are a density-independent limiting factor, since they do not depend on other factors to occur, but only on the movement of our planet's plates.

Finally, limits population regardless of how many organisms are present in the area is a density-independent limiting factor, since they do not depend on how many organisms they're to limit the increase of the population. Being this option an abiotic kind of non-limiting factor.

The experiment examined the roles of genes and environmental temperature in the sex determination of a lizard species. The species has two types of chromosome pairs: ZW and ZZ. Individuals with a ZW pair of chromosomes are always female, while individuals with a ZZ pair of chromosomes can be either male or female.

To test the effects of genes and temperature on sex determination, scientists mated ZWf or ZZf females with ZZm males and incubated the eggs produced at different temperatures ranging from 23°C to 36°C. The hatchlings' sex was determined, and the data was collected in Table 1. The experiment found that at lower temperatures, the majority of hatchlings were female, regardless of their genetic makeup. At higher temperatures, there were more male hatchlings. These findings suggest that both genes and environmental temperature play a role in sex determination in this lizard species. The experiment also found that the mortality rate of embryonic lizards was approximately the same for both males and females.

The findings of this experiment are relevant to understanding the evolutionary biology of reptiles, as well as to conservation efforts for threatened or endangered species. For example, scientists studying endangered reptile populations may use temperature manipulation as a tool to encourage the production of males or females, depending on which sex is more needed to maintain a healthy population.

Overall, this experiment highlights the complex interplay between genetic and environmental factors in determining an organism's traits and characteristics, including its sex.

Answer:

The answer is 46 chromosomes.

Before mitosis, cell duplicates its DNA material so there are 46 chromosomes in duplicates and in total there are 46 x 2 = 92 sister chromatids. During mitosis, sister chromatids first join in the middle of the cell and then separate towards the opposite sides of the cell. After they separate, there are 46 sister chromatids on the one side and 46 sister chromatids on the other side. Each sister chromatid at the end of cytokinesis actually represents the chromosome of the newly formed daughter cell.

If the citric acid cycle is unaltered, as indicated, then energy would be obtained from FADH2, NADH, and ATP to run the citric acid cycle in reverse. CO2 would be the initial carbon substrate. Hence (c) is the correct option.

Acetyl-CoA, an important source of carbon for the citric acid cycle, can come from either glucose or fatty acids, but the latter source—pyruvate—provides the majority of acetyl-CoA. The metabolic conversion of pyruvate to acetyl-CoA is facilitated by the pyruvate dehydrogenase complex (PDC). ATP is produced throughout the citric acid cycle by substrate-level phosphorylation.
