after the formation of the neural tube, the number of cells destined to become part of the adult nervous system

◯ increases rapidly
◯ quickly doubles and then declines
◯ actually declines
◯ stays the same until the end of the neural - groove phase
◯ stays the same until the end of the neural - plate phase

Explanation:

During neural development, after the neural tube forms, there is a process of apoptosis (programmed cell death) that occurs. This leads to a decline in the number of cells destined for the adult nervous system. It is a normal part of development to refine and optimize the nervous system structure.

Answer:

actually declines
