Answer:

phenotype or trait

Explanation: if it is really cold a mouse with thicker fur (phenotype) will do better

Environmental conditions often favor one selection over another.

In the context of evolution, selection refers to the process by which certain traits or characteristics become more or less common in a population over time. This process occurs due to environmental conditions that favor certain individuals with advantageous traits, leading to their increased survival and reproduction.

For example, consider a population of birds living in a forest with two distinct color morphs: light and dark. If the forest becomes darker due to increased tree cover, the dark-colored birds might be better camouflaged and have a higher chance of surviving and reproducing. Over time, the proportion of dark-colored birds in the population would increase, as they have a selective advantage in the new environmental conditions.

Similarly, if the forest becomes lighter, the light-colored birds may become more successful in avoiding predation and finding mates. In this case, the environmental conditions would favor the light-colored birds, leading to an increase in their frequency within the population.

Therefore, the term "selection" refers to the process by which environmental conditions favor certain individuals or traits, resulting in changes in the frequency of those traits within a population over time.

The polysaccharide that is responsible for the strong structural nature of cell walls of plants is cellulose.

The cellulose is an organic molecule that is made up of several units of glucose monomer. The cellulose which make up a large percentage of plant cell walls are composed of a network of several units of glucose monomer that are tightly linked together.

The cellulose, as well as lignin and hemicellulose, which constitutes the tensile fibers in the cell walls of plants, is the polysaccharide responsible for the strong structural nature of plant cell walls.

Explanation:white moths will be spotted easier and killed and the population would drop while the dark moths population will rise

The population of white moths at the light tress will increase over time with the process of natural selection.

The trees are a light color population. Dark moths are unable to camouflage with the tress, while white moths camouflage with the trees.

The white and black moths at the tree are an example of a tree ecosystem. The moths are the target for the predators.

The process of natural selection is the evolutionary process with the survival of the fittest. The species that are able to survive in the inappropriate conditions are able to evolve.

In the tree ecosystem, the white moths are camouflaged with the trees. They will not be an easy target for predators. They will survive with the theory of natural selection.

The black moths are not camouflaged with the tree ecosystem. They are easily identified by the predators and are killed.

Thus, white moths are the fittest and with natural selection, they evolve.

Therefore, the population of white moths at the light tress will increase with natural selection.

d) the laws of independent assortment

Explanation:

just took it

I think thats because small animals have small body that can hide in a safe place. Like example if small animals hide go down to the earth, and the meteorite hit the earth, they will safe down to the ground.

Not like larger animals, they can only hide up he surface and when the meteorites came, they died.

Also some small animals such as cockroaches have ability to adapt to changes.

Answer:

Due to the presence of larger vessels.

Explanation:

Due to the presence of larger vessels of hardwoods in the tree, water move faster in that tree as compared to other type of plants. in smaller plants, small vessels are present which able them to move less amount of water as compared to large trees which have large vessels. It tells us that the tree adopted the environmental changes so that's why to overcome the change, they use more water.

C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?

Independent assortment is a mechanism that contributes to genetic diversity during meiosis. It refers to the random alignment and separation of homologous chromosomes during the first meiotic division (meiosis I), which leads to different combinations of chromosomes being passed on to the daughter cells.

This means that each daughter cell will have a unique combination of chromosomes. When the gametes (sperm or egg cells) produced by meiosis fuse during fertilization, they can give rise to offspring with a unique combination of genetic information, further increasing genetic diversity within a population.
