23, human gamates have 23 chromosomes.
Answer:
Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil. The final stage of succession is a climax community, which is a very stable stage that can endure for hundreds of years.
Anything can come out of that but I think type b might be more possible to happen.
Answer:
B is the answer. I hope this help you
Answer:
Median height is selected
Explanation:
Stabilizing selection is a particular type of natural selection where the mean of the trait in the population stabilizes on non-extreme phenotypes, thereby favoring intermediate phenotypic variants. At genetic level, stabilizing selection is shaped by selective forces that push the distribution of the trait in the population toward the average (median trait), it is a condition that may happen when a population is completely adapted to its environment. Thus, stabilizing selection acts to purge the extreme phenotypic variants via purifying selection. Stabilizing selection is considered to be one of the most important mechanisms controlling the distribution of different phenotypes after many cycles of artificial selection, it s for that reason that breeders believe that this type of natural selection is the most common in nature.
