For the answer to the question above asking what does the pyramid of biological magnification. Biomagnification, also known as amplification or biological magnification, is the increasing concentration of a substance, such as a toxic chemical, in the tissues of organisms at successively higher levels in a food chain. <span>DDT was a commonly-used pesticide before its dangers became known. In some aquatic ecosystems, organisms from each trophic level consumed many organisms of the lower level, which caused DDT to increase in birds (apex consumers) that ate fish.</span>
Two human examples of multiple-allele<span> genes are the gene of the ABO blood group system, and the human-leukocyte-associated antigen (HLA) genes. The ABO system in humans is controlled by three </span>alleles, usually referred to as IA, IB, and IO<span> (the "I" stands for isohaemagglutinin).</span>
It is a behavioral adaptation.
There are three types of adaptations:
Structural - body parts that help it survive (e.g. color, size, shape)
Physiological - systems present in an organism that allow it a special feature (e.g. venom, skin color changes)
Behavioral - an action that allows the organism to better survive
Answer:
Natural selection also affects allele frequency. If an allele confers a phenotype that enables an individual to better survive or have more offspring, the frequency of that allele will increase.
