a) Meiosis
Explanation:
Meiosis is a form of cell division that occurs in sexually reproducing animals' germ cells and is utilized to create gametes such as sperm and egg cells. It takes two rounds of division to produce four cells, each with only one copy of each chromosome.
Strengthening some synapses and weakening others establishes neural circuits that contain memories; the low-frequency stimulation of synaptic inputs to a cell can <u>decrease</u> their strength in a phenomenon known as <u>long-term</u><u> depression</u>.
The effect of long-term depression can arise from neural effect of synapses. The synaptic impulses start to decrease gradually when a person is suffering from long-term depression. This decreased neural synapses arise from long-term exposure to stress that is chronic. It can also stem from anxiety. The continuous exposure of the neurons to stress and anxiety can also lead to degeneration and depletion of the cells present in the nervous system. Also the cortisol levels rise during depression and it is regulated by the hippocampus. This leads to a delay or restriction in the developing neurons inside the brain. Long-term depression can lead to increased chances of getting addicted to alcohol or drugs.
