All light moths will be better camouflaged on lichen-covered trees. So, their predators could hardly notice moths on the trees and number of predators will decrease for a while. Predators could then change hunting strategies or seek for other sources of food. Also, let's assume there is variability in eyesight between predators, so those with better eyesight will have greater chance to notice moths and will become more common.
Answer:
a) 3 cromosomes b)3
Explanation:
The haploid number of a cromosome is the total number ofcromosomes withoutits homologue partner. In this case, if the text indicates that the haploid number of cromosomes is 6, then that is the total number of cromosomes in the result cell.
The ovum contains just half of the information that will be given in order to form the new organisms, in this context, if the result organism has cromosomes, the ovum will only contain 3.
In meiosis II, after both cigotes get together and unite all the 6 cromosomes, it separates again. This means that the second polar body will remain will only 3 cromosomes again.
Answer:
Updrafts continue to fuel the storm with warm, moist air. But, once a storm runs out of updrafts, it starts to weaken. As a storm begins to slow down, the rain and wind become less intense. And by the end, all that's left is a blue sky and an anvil-shaped cloud top.
