Answer:A) Nitrogen
Explanation: nitrogen cycle ensures the movement of nutrients through the biosphere.it ensures that nitrogen is constantly reused and made available.
Nitrogen gas is available in the atmosphere but plants and animals cannot use it in that form.it must be converted to compounds such as ammonia or nitrate.
It is gotten from the atmosphere during rainfalls where it Is broken down and combines with oxygen to from nitrogen peroxide.
Nitrogen can also be fixated into ammonia by saprophytic bacteria.
Also when plants die their body tissues are broken down to form ammonia.ammonia can be oxidized into nitrates and nitrite which plants can use.
Nitrites can be released back into the atmosphere through denitrifying bacteria and the cycle continues.
Main parts and their functions :
- Hypothalamus : Links the nervous system to the endocrine system via the pituitary gland. It controls the release of 8 hormones by the pituitary gland, controls body temperature, control of food and water intake, hunger and thirst!
- Pituitary gland : Produces essential hormones for everything living such as the growth hormone, adrenocorticotropic hormone, thyroid stimulating hormone, luteinizing hormone and follicle stimulating hormone, etc.
- Thyroid gland : Produces thyroid hormones that regulate the body metabolism, play an important role in bone growth and development of the brain and nervous system in children!
- Parathyroid glands : Release parathyroid hormone which plays a role in regulating calcium levels in the blood and bone metabolism.
- Adrenal glande : Produce hormones that help the body control blood sugar, burn protein and fat, react to stressors, and regular blood pressure.
- Pineal body/gland : Secretes the melatonin hormone which may help regulate the wake-sleep cycle of the body.
- Reproductive glands : Main source of sex hormones for males and females.
- Pancreas : Has digestive and hormonal functions. One part of the pancreas called the exocrine, secures digestive enzymes. While the other part of the pancreas called the endocrine, secretes hormones called insulin and glucagon. Overall, these hormones regulate the level of glucose in the blood.

the hair follicle, before shedding in the telogen phase. The longer the anagen
phase the longer the hair will be before shedding. The hair on the head has
longer anagen phase compared to hair in regions such as the eyebrows.
