The word in the blank should be 'segregation' :)
Answer:
adrenal
Explanation:
The adrenal glands are two endocrine glands in the human body. They are located above the kidneys. Members of the endocrine system, the adrenal glands are very important to the human body because they make hormones essential for their functioning.
These glands are also responsible for the production of hormones that act on the transformation of fat into glucose by the liver. An example of this hormone is glucocorticoid known as cortisol, which also acts on the degradation of triglycerides. These functions are also performed by the region of the adrenal cortex.
The adrenal glands also produce in the adrenal medulla two other important hormones: adrenaline (also known as epinephrine) and norepinephrine (also known as norepinephrine). These two hormones act on psychic and physical reactions generated by strong emotional situations (mainly related to emotional stress).
Elderly people are most at risk
from minor trauma that results in serious spinal cord injury because of
preexisting degenerative vertebral disorders. Males are more prone to spinal
cord injuries than females but not as a result of preexisting disorder. This
may be related to an increased involvement in contact sports or a propensity to
participate in high risk activities. Neither females nor infants are at any
particular risk for spinal cord injuries.
Petroleum Products
Petroleum and its products are mainly composed of carbon polymers (chains), as the backbone, with different structural and functional groups. Plastic, for example, is made of polypropylene and polybutylene which is mainly made of carbon atoms, whose monomers are linked in a chain to form polymers that make up the products.
Synthetic rubber on the other hand is made of copolymers of carbon and other addictives such as styrene. Synthetic fiber is made of nylon that is composed of a copolymer between carboxylic acid and amides.
Carl Von Linneaus developed the system for classifying organisms.
