Answer 1

The. Correct answer for the questions are

Question 1 homeostasis is ability of the body to quickly restore the changed the condition to normal so option c is correct

Question 2 glucose is completely reabsorbed in pct so option c is correct

Question 3 thiazide diuretics inhibits nacl contransport in fact as primary action option a is correct

Question 4 adh receptors are present on plasma membrane of of collecting tubules cells option d is correct
