During apoptosis:
A)neurons die as a result of accidents or disease.
B)neurons with fewer connections to other neurons are more likely to survive.
C)there is an increase in neurotrophic factors such as BDNF.
D)about 1/3 of the neurons die.

Question

Quizplus · Accepted Answer

During apoptosis, approximately 1/3 of neurons die as a normal process of development and maintenance. This helps to eliminate cells that are no longer needed or are a potential threat to the organism. Neurons do not necessarily die as a result of accidents or disease, and the number of connections to other neurons does not necessarily determine survival during apoptosis. While neurotrophic factors are important for promoting neuronal survival and growth, they are not typically increased during apoptosis.
