Answer:

vaccines were designed by using new technologies (i.e., RNA-based vaccines and adenovirus-based vaccines)

Explanation:

RNA-based vaccines are vaccines based on the delivery of specific messenger RNA (mRNA) sequences that are capable of encoding only one viral protein, thereby preventing the complete viral cycle/replication. Subsequently, this protein is recognized by the immune system that generates memory immunity by synthesizing specific antibodies against this protein (in this case, the spike S protein). On the other hand, adenovirus-based vaccines are vaccines designed by inserting a transgene cassette into an adenovirus which is used as vector to produce one specific viral protein inside the host. Like mRNA vaccines, this antigenic viral protein is then recognized by the immune system in order to produce antibodies against a defined protein epitope, thereby producing memory immunity.

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.
