Answer:
The correct answer is "two examples of how radar installations might cause hazard to human health are: decreased ability to perform mental tasks and induction of eye cataracts".
Explanation:
According to the World Health Organization electromagnetic fields below 10 Gigahertz of power do not represent a threat to human health, which make most radar installations safe for operation. However, some studies performed in primates by the exposure of increasing levels of electromagnetic fields have shown that they can developed a decreased ability to perform mental tasks and induction of eye cataracts. This is explained by the exposure of electromagnetic fields that can increase the animals' body temperature by one centigrade.
The correct answer is d. spinal cord.
Spinal cord is a bundle of neurons which starts from the brain and runs down the entire length of the back of the body. The spinal cord acts as a main means to transmit the messages between the brain and the body.
Sensory or efferent neurons carry the information from the perimeter of the body and pass to the central nervous system whereas the motor or efferent neurons act as a communication channel and carry the information from the nervous system to various glands and muscles.
The structure is a helix structure.
The four bases are
adenine (A), guanine (G)
cytosine (C), and thymine (T).
The pairing are
Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine
When an individual's cortisol levels are low, such as in the case of people with Addison's disease, the hypothalamus region of the brain releases corticotrophin-releasing hormones. This causes the pituitary gland to also secrete another hormone called, adenocortocotropic hormone into the bloodstream. <span>When the adrenal glands detect these hormones, they secrete cortisol, causing blood levels of cortisol to rise.</span>
