Answer:
C) Population bottleneck reduced genetic diversity, as the gene pool of the 30,000 elephant seals resulted from the few alleles present in the 20 bottleneck survivors.
Explanation:
<u>The correct answer would be that population bottleneck reduced genetic diversity, as the gene pool of the 30,000 elephant seals resulted from the few alleles present in the 20 bottleneck survivors.</u>
A sudden decrease in the population of an organism as a result of disaster or any other factor leads to a population bottleneck - a decrease in the genetic variability of the population.
<em>The decrease in the available number of alleles in the population limits the amount of genes that natural selection can influence. Hence, as the population keeps increasing, the genetic diversity of the entire population rarely changes because the few alleles present in the population keep recombining.</em>
The correct option is C.
Answer:
Muscular system--helps the body move.
Skeletal system-- provides structur to the body.
circulatory system-- circulates oxygenated blood through the body.
respiratory system-- exchanges gases in the body.
integumentary system-- helps receive signals from the outside world.
Is it multiple choice or something bc I don't get it.
It would have a knock on effect
the flood possible would destroy vegetation, leads to a decrease in the numbers of primary consumers , then secondary an so forth.
