Answer:
A
Explanation:
Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. The size and coding capacity of the mitochondrial DNA varies considerably in different organisms, and encodes rRNAs, tRNAs and essential mitochondrial proteins.
Specialized ganglionic sympathetic neurons that release hormones into the bloodstream are found within the adrenal glands.

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.

The process of turning off and on of genes is known as gene regulation.
Explanation:
When the gene is turned on, it instructs the cells to construct a particular protein. The proteins are the molecules that build your body with collagen, tendons, and bones or keratin in your hair.
The gene regulatory proteins allow the individual genes of an organism to be turned on or off . in different cell types there are different selections of gene regulatory proteins. The patterns of the gene expression gives each cell its unique characteristics.
Each cell produces or turns on only a fraction of its genes. the remaining genes are repressed or turned off. this process is known as gene regulation. The signals from the environment or from other cells activate proteins called transcription factors.
