oil is not a good conductor of heat
Spirulina is a type of cyanobacteria. The cyanobacteria are a type of bacteria that have pigments that allow them to photosynthesize. Which organelle allows a plant to photosynthesize?
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.
