Answer:
cell migration occurs during vital cellular processes such as tissue renewal and repair, wherein old or damaged cells are replaced by the migration of newly formed cells from the underlying tissue layers.
The cells that can become many different types as they mature are ___________.
Answer: Stem cells

What could be the effects of a population changing drastically over a short period of time?
Answer: Causes of population decline
The size and demographics of the population change when:
fewer children are born;
families with children move to larger towns and cities;
young and better-educated people move to larger towns and cities.
Effects of population decline
When young people move to bigger towns and cities, the average age of the population in the place they leave behind automatically goes up. A community with a higher proportion of older inhabitants may be less attractive to businesses, which may additionally have difficulty finding suitable staff locally. Other effects of population decline include:
fewer schools, due to there being fewer children;
a drop in house prices because more homes are unoccupied;
fewer new homes being built;
less demand for rented accommodation;
fewer care facilities;
less turnover for shopkeepers and businesses;
fewer sports facilities;
fewer people going to the theatre, cinema or concerts, so these facilities are eventually cut back;
fewer people travelling by public transport, which thus costlier to run;
local residents have to travel further to reach the facilities they want.

The axon of a sending neuron is separated from the dendrite of a receiving neuron by a.
During neuronal communication, the axon of a sending neuron is separated from the dendrite of a receiving neuron by a synaptic gap, also known as synaptic cleft or space.
What is the synaptic gap?
During synapsis, a presynaptic neuron sends information to the postzynaptic cell.
The axon of the sending neuron releases neurotransmitters through exocytosis forward to the dendrite of the postsynaptic cell.
The synaptic gap, or synaptic space, is the space left between the axon of the sending neuron and the postynaptic membranes.
The neurotransmitter travels through the synaptic gap forward to the other neuron.
Once it reaches the target, it binds to its receptors in the postsynaptic membrane.
This binding produces a depolarization of the cell called an excitatory postsynaptic potential.
So, the axon of a sending neuron is separated from the dendrite of a receiving neuron by a synaptic gap, also known as synaptic space.
