Answer:
cells of the body
Explanation:
Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell’s cytoplasm, energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move. Don't confuse respiration with breathing. Respiration releases energy, while breathing
Answer:
Somatic hypermutation is a process in which point mutations build up in the antibody V-regions of both the heavy and light chains.
This process occurs at rates that are about 106-fold higher than the background mutation rates observed in other genes.
It allows B cells to mutate the genes that they use to produce antibodies. This then ensures the B cells to produce antibodies that are better able to bind to bacteria, viruses and other infections.
The correct answer is C. Estivation
Explanation:
In biology, estivation refers to a lethargic state that is mainly prompted by high temperatures, different from hibernation that occurs in the winter or at low temperatures. However, as hibernation estivation implies the organism of animals lowers the metabolic rate with the purpose of avoiding to die due to the high temperatures and the lack of resources including water. This can occur in both vertebrate and intervertebral animals including small animals. This implies, the mouse described which is a small animal probably is going through estivation as due to hot temperatures the organism lowers the metabolic rate, which is exactly what occurs in this process.
Answer:
The dairymaids possessed immunity against the more extreme smallpox as due to getting exposed to cowpox, the body of the dairymaids generated certain kinds of substance to defend against the cowpox, which also helped in defending smallpox.
When Edward Jenner found that the dairymaids suffering from cowpox possessed immunity towards smallpox, he concluded that the emergence of cowpox at the same time developed immunity towards smallpox. To ensure, Jenner collected a fluid sample from the pustule of cowpox and administered it within a boy's body, and thus, discovered the principle of immunity.
