Question 1 of 5
Podocytes
Correct Answer: D
Rationale: Podocytes have secondary processes (pedicels) contacting the basal lamina, form the visceral layer, and contain actin microfilaments all true. This comprehensively describes podocytes, key for filtration slits, contrasting with partial descriptions.
Question 2 of 5
Collecting duct
Correct Answer: D
Rationale: Collecting ducts have principal (light) and intercalated (dark) cells, respond to ADH, and concentrate urine all true. This fully describes their role, key for water balance, contrasting with partial traits.
