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.
Answer:
The process by which chemical elements of the matter and energy moves between the biotic and the abiotic component of the biosphere along with dissipation of energy as heat to the atmosphere is generally termed as biogeochemical cycle.
Explanation:
The energy flows across food chain with entry in the form of sunlight and moves along the food chain until it is dissipated as heat. The matter which forms the basic components of the biotic part namely water, carbon, nitrogen, oxygen, phosphorus and sulfur are recycled gradually on moving through the food chain. The biogeochemical cycle may be water cycle which is most important for survival of life. Carbon cycle includes the macro molecules of organic nature and even the fossil fuels. Nitrogen cycle includes DNA, RNA and protein. Likewise all the biogeochemical cycle are invariably connected to the food chain and forms integral part of it.
In bioinformatics, a sequence alignment is a way of arranging the sequences of DNA, RNA, or protein to identify regions of similarity that may be a consequence of functional, structural, or evolutionary relationships between the sequences

B or C sound like good answers but I would choose B.
