The right answer is B. controlling the flow of blood to the skin
When the body temperature is below the set point, the hypothalamus activates several thermogenesis mechanisms:
* Vasoconstriction on the vessels near th skin by the sympathetic nervous system to reduce thermal exchanges between the skin and the surrounding environment.
* And increase in heat production:
-by muscular activity:
-by the metabolism:
Answer:
1. Lupus
2. Cardiovascular disease
3. Huntington disease
4. Cancer
5. Diabetes
Explanation:
A disease can be defined as any harmful or abnormal deviation of the body of a living organism from its functional state or normal structure, which is typically accompanied by certain signs and symptoms.
Basically, a disease negatively affects the function or structure of the body of a living organism.
The different types of diseases experienced by living organisms include the following;
1. Lupus: occurs when the immune system attacks the body. It is referred to as an autoimmune disease.
2. Cardiovascular disease: is often caused by obesity resulting from overeating and poor nutrition.
3. Huntington disease: is caused by DNA changes in a single gene and affects the nerve cells in the brain.
4. Cancer: is caused by uncontrolled cell growth.
5. Diabetes: occurs when the pancreas does not produce enough insulin, or the body does not respond properly to it.

Answer:
D. Small population size
Explanation:
Hardy-Weinberg equilibrium requires the presence of a large randomly mating population. Small population size makes the population more likely to deviate from the Hardy-Weinberg equilibrium due to sampling error or chance events occurring during the genetic drift. Large population size ensures that the population maintains the constant allele frequencies over generations, that is the Hardy-Weinberg equilibrium.
