Mutations result from an error in DNA replication, should it be from an alien source (like radiation) or simply a mistake in replication.
Migration of organisms to a new population would alter the DNA by adding new genes, but it would not mutate them.
Specialized ganglionic sympathetic neurons that release hormones into the bloodstream are found within the adrenal glands.
<h3>
What is adrenal gland?</h3>
- A little gland that produces noradrenaline, adrenaline, and steroid hormones.
- These hormones assist in maintaining healthy blood pressure, heart rate, and other vital bodily functions.
- Immune system, blood pressure, stress response, metabolism, and other critical processes are all controlled by hormones that are produced by adrenal glands.
- The cortex and the medulla, the two components that make up an adrenal gland, are each in charge of manufacturing a separate hormone.
- Problems with one, both, or other glands, such as the pituitary gland, can result in diseases of the adrenal glands.
- When the adrenal glands create either an excessive amount of hormones or an excessive amount of hormones from external sources, several diseases may arise.
- Since the adrenal glands are essential for human survival, if both are destroyed, the patient will need to take drugs and hormone supplements.

Answer: Natural selection can be defined as the differential survival and reproduction of members of the population of a species that have suitable traits to survive in a population of species.
Explanation:
The punctuated changes in the population of species have been found inordinately faster in the geological time scale, but changes per-generation have been relatively slow. Also, the rate of evolution in such a population is also slow. The punctuated changes in the population are because of evolution but the per-generation changes are the outcomes of the natural selection, in which only the beneficial traits are passed from one generation to another.
