A young woman enrolls in courses at a local college. She attends classes
regularly and actively participates in
class activities and discussions. She
spends much of her free time studying
on campus, either alone, or with student
study groups. Outside of class, she is
involved in several student
organizations. Which of the following
theoretical perspectives would explain
the student's active participation in the
college community as motivated
primarily by a powerful need to gratify
primal urges for sexual pleasure?

Uhh, is this even appropriate?

Explanation:

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.
