Answer:
C. Characters with little genetic variation will constrain the rate of natural selection
Explanation:
Natural selection can have an effect only as long as there are variations on characters on which it can select upon. Genetic variation is independent of the environment or the needs that a species may have to become better adapted to its changing environment. In other words, genetic mutations are the raw material on which natural selection can work. If there is a low rate for mutations to occur, then natural selection will proceed at a slow pace. The opposite is also true. Since mutation rate may be more frequent at some locations in a gene than at others, it can be predicted that the characters coded in that gene location will be more likely to be affected by natural selection and therefore what phenotype may be molded by natural selection.
Answer: The science of naming and classifying organisms based on structural comparisons and genetic evidence, is known as taxonomy, a branch of biology.
Explanation: Taxonomy is very important. By categorizing organisms, this branch of biology helps scientists to exchange vital biological information, and therefore understand the diversity of species in our planet.
Answer: C - spiral staircase
Explanation:
My answer will be because these characteristics intervene in the capture and assimilation of the food, having 4 general food behaviors: (1) detritivores, consume a lot of material from the bottom of the water source, (2) herbivores, who consume mostly plant components (filamentous algae and higher plants); (3) periphyton consumers, who are characterized by feeding on microalgae and microinvertebrates and (4) omnivores, in which they indistinctly feed on plant material as an animal of different origin.
D, correct me if i’m wrong
