Identify two chemicals in digestive juice in the stomach and explain what they do

- enzyme pepsin: chemically digests the proteins in the food, breaking down into amino acids

- hydrochloric acid (strong acid): provides an acid environment for pepsin and kills bacteria (food); without this acid, the stomach could not function properly.

c-reactive protein (crp) is an acute phase protein belonging to pentraxin family of proteins, whose levels increases 1000-fold or more in concentration in blood during the occurrence of an injury, inflammation or tissue death.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
