Answer and Explanation:

The hypothalamus contains the central thermoreceptors which detect blood temperature as well as the thermoregulatory centre. The skin of organism contains peripheral thermoreceptors which detect the environmental temperature.

Increase in body temperature above the normal initiates the appropriate corrective mechanisms that include sweating, lowering of hair for mammals, vasodilation of superficial blood vessels and decrease in metabolic rates. This has an overall effect of causing the body temperature to fall and the normal body temperature is restored.

Sweat is secreted by sweat glands that evaporates from the surface of the body cooling the body as it absorbs latent heat of vaporization. Superficial blood vessels vasodilate so that more blood flows near the surface to encourage heat loss. Hair is lowered so that it lies against the body surface. This encourages heat loss from the body to the external environment.

What do we mean when we say that there is a "Consilience of Evidence" supporting a theory?
Gnoma [55]

The correct answer is C) That scientists who have worked on the theory have independently and repeatedly come to the same conclusions over time.

Explanation:

In science, the term "consilience of evidence" is used when the evidence of a hypothesis or theory is consistent especially evidence from independent scientists or sources. This often implies the theory has been tested many times and by different experts and even using different methods but the results are always the same. This consilience of evidence is essential to declare a theory as valid and concluding. In this context, the option that describes the meaning of this term is C.
