Answer:
It involves alternating haploid and diploid phases. alternation of generations is the term that is used to the life cycle that happens in plants and algae.
Explanation:
Genetic variation describes the genetic differences among individuals of the same species that are naturally occurring. <span>Each genotype within a population usually has different degrees of fitness to an environment. Mating between same species with favored genes guarantees survival of the population in their chosen environment. As the environment changes, the mating behavior between species may again change resulting to a different gene pool to guarantee survival. </span>
The environment only has enough resources to support 250-300 of this organism.
<h2>Answer:</h2>
This means the dolphin is an vertebrate.
<h3>Explanation:</h3>
- Gill pouches are the structures which are present in all vertebrates in the embryonic stages while it is present in fishes and amphibian in later life also.
- It is thought to be the ancestral structures present in vertebrates. These pouches are then converted to lungs in the later life. For the water animals they are used for respiration.
- They are actually the muscular walls containing respiratory lamellae on its inner side.
- Hence in dolphin they are signs that dolphin is an vertebrate.
