The whales are the predators of seals. If the death rate of whales is high then the population of seals will rise, especially if
their birth rate is faster. Therefore the carrying capacity of seals will be higher than whales. With no different except birth rate in seals it will not drastically effect the carrying capacity, whales will still have a higher capacity.
In meiosis, the chromosome pairs do the crossing over where there is an exchange of genetic material between them and because of it the
chromatids held together by the centromere are no longer the same.
