both can do sexual offspring
Explanation:
bud that's one of them
<span> A virus is not a living thing so antibiotics, intended to kill living things, are not effective. A virus cannot multiply outside a living host cell. There is no treatment for a virus, just supportive therapy. The body will fight off most viruses over the course of time. Vaccines do not cure viruses, so the only way to protect your goat from viruses is through specific vaccines.
So the answer is a virus</span>
Answer:
b. the bottleneck effect.
Explanation:
The bottleneck effect occurs when a population's size is reduced for at least one generation. This will result in a very reduced genetic variation, which can lead to further adaptation problems.
The Founder effect has its similarities (in terms of the resulting reduced genetic pool) with the bottleneck effect, BUT it occurs when a new colony is started by a few members of the original population.
The Hardy-Weinberg equilibrium is a principle in population genetics that states that the genetic variation in a population will remain constant from one generation to the next IF certain conditions are present (no migration, aleatory mating, among others), so this is not the answer.
Genetic drift (refers to the change in the frequency of an existing gene variant in a population due to random sampling of organisms, so it is not the answer.
The environment is the ultimate filter for which traits are maintained by natural selection. If a trait makes it easier to live in an environment, then that trait will be maintained. If a trait is makes it difficult to live in an environment, then that trait will be discontinued or removed.
