Why does change in body temperature occur

Reasons why body temperature can INCREASE:

•  Being in a warm environment because the external heat up the blood in your body

• Exercising because respiration occurs, which releases energy by using up food stores in the body.

•  When you have a flu or a virus, because pyrogens (chemicals which regulate body temperature) builds up in the hypothalamus (a section of the front of the brain).

Reasons why your body temperature can DECREASE:

• It can decrease when you are too hot, because your body releases sweat from the sweat glands on your skin which evaporates. Also, your blood vessels become narrower (a process called vasoconstriction) so that it lose less heat and is further away from the surface of the skin.

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
