Answer:
The correct answer is option C. "pleiotropy".
Explanation:
Pleiotropy is a characteristic that defines a gene that is responsible for the development of multiple traits, which often seem to be unrelated. Sickle-cell disease is an example of a disease caused by the mutation of a pleiotropic gene, resulting in the person developing red levels, blood clots, and strokes. Other example is the disease phenylketonuria, at which the affected person suffers from a mental disorder and reduced hair and skin pigmentation by a single mutation in a single gene on chromosome 12.
Answer: Option A) secreting antibodies from eccrine glands
Explanation:
The eccrine glands, a type of sweat gland found in the deep layer of the skin provides protection from infection by producing sweat that is majorly composed of water, but also immunoglobins.
These immunoglobins are designed to respond to foreign and potentially harmful pathogens, removing them and protecting the body.
Thus, the answer is secreting antibodies from eccrine glands
Answer:
B) how changes in development underpin the evolution of morphology.
Explanation:
Evolutionary developmental biology is the new field of research in biology which studies the combined relationship of the evolution and the developmental processes.
This interdisciplinary study compares the developmental biology in terms of evolution or in a way that how the developmental biology process evolved in the organism on the basis of studying the phenotypic features of the organisms.
Thus, Option-B is the correct answer.
