The enzyme(s) called ____________ break(s) down the substrate called_________________.
lactose; lactase
lipases; micelles
peptidases; proteins
lactase; glucose
The Correct Answer is C
A. Lactose; lactase: Lactase is the enzyme that breaks down lactose, not the other way around.
B. Lipases; micelles: Lipases break down lipids (fats) into fatty acids and glycerol, not micelles. Micelles are formed as part of the digestion process but are not the substrate for lipases.
C. Peptidases; proteins: Peptidases (or proteases) break down proteins into smaller peptides and amino acids. This is the correct answer.
D. Lactase; glucose: Lactase breaks down lactose into glucose and galactose, not just glucose.

C. The size of their renal corpuscle: The renal corpuscle size does not differ significantly between cortical and juxtamedullary nephrons.
D. Whether they drain into a collecting duct or directly into the renal pelvis: All nephrons drain into a collecting duct; none drain directly into the renal pelvis.
Correct Answer is A
Explanation
A. Y chromosome: The SRY gene on the Y chromosome codes for the testis-determining factor (TDF), which initiates the development of testes and male characteristics.
B. Gonadal ridges: The gonadal ridges are the precursor structures that develop into gonads but do not contain the gene for TDF.
C. X chromosome: The X chromosome contains genes important for development but does not code for TDF.
D. Fetal testes: The fetal testes produce testosterone but are not the source of the TDF gene.
