Homeostasis is the ability of an organism to stabilise its internal body metabolism in response to changes in the external environment. The ability to carry out homeostasis provides an organism a lot of freedom from the dependence on the external environment. For example, reptiles are cold blooded animals. They require the heat of the sun for body metabolism. But in the absence of heat or in case of harsh winters, the reptiles will not be able to adjust to the temperature and as a result perish. Mammals are warm-blooded animals, being able to regulate their internal body temperature as and when necessary. Winters will affect the warm-blooded animals less because their body will increase in metabolism in response to cold temperatures to raise the internal body temperature. This is possible only through homeostasis.
Assuming that Element X is neutral or the atom of element X is neutral or uncharged it will possess the same number of electrons which is 80.

Explanation:
Neurons are longest animal cell that serve as the basic unit of their nervous system.
The neuron is divided into two parts-
Cyton: It is the cell body of the neuron. It has projection extending from the cytoplasm that receive signals called dendrites.
Axon: It is a long process extending from the cyton that carries the impulse from cell body to end of neuron. The axon terminate at knob like structures called terminal button . These release neurotransmitter and are rich in mitochondria.
