Answer:
"I should call the primary healthcare provider for dry hair and an intolerance to cold."
Explanation:
Dry, sparse hair and cold intolerance are characteristic responses to low serum thyroxine. Muscle cramping is associated with hypocalcemia. Low thyroxine levels reduce the metabolic rate, resulting in fatigue, but do not increase the pulse rate. Low thyroxine levels reduce the metabolic rate, resulting in weight gain and bradycardia, not tachycardia.
Answer:
The limbic system.
Explanation:
The limbic system is the part of the brain involved in our behavioral and emotional responses, laughter for example, or aggression, as it is the case here. It controls some behaviors that are essential for survival: finding food, reproduction and self-preservation. It is a network of structures located beneath the cerebral cortex and above the brainstem. The two of the major structures of the limbic system are the hippocampus and the amygdala.
