Apoptosis plays a role in human development in all of the following except:
A) Removal of interdigital webs of the hands and feet
B) Formation of the blood vessels and the gastrointestinal tract
C) Differentiation (divergence) of mast cells and basophils
D) Selection of appropriate T and B lymphocyte clones

Question

Quizplus · Accepted Answer

Apoptosis, or programmed cell death, is crucial for removing unnecessary or harmful cells during development and maintaining homeostasis in mature organisms. It is involved in shaping structures by removing cells, such as in the interdigital webs (A), and in the immune system by selecting functional T and B cells while eliminating those that are self-reactive or non-functional (D). However, the differentiation of mast cells and basophils (C) is a process of cell development and maturation, not directly related to apoptosis. Apoptosis does not play a direct role in the differentiation of these specific cell types.
