29. Which of the following pairs are mismatched a. marine fish-hyperosmotic regulators b. molluscs-isosmotic regulators c. freshwater animals-hyperosmotic regulators d. Marine reptiles-hyposmotic regulators 30. For land dwelling animals total Evaporative Water Loss (EWL) is the result of a. Integumentary water loss b. Respiratory water loss C. Urination d. a and b 31. Freshwater animals tend to a. lose water and gain ions. b. gain water and ions. c. gain water and lose ions. d. lose water and ionsExplanation / Answer
29 (a) Marine fish -Hyperosmotic regulators
Reason: marine fish drink salt water continuously ,water leave the body continuously hence hypoosmotic
30.(d) a and b
Reason:TEWL= sum of cutaneous water loss and respiratory water loss
31.(c) gain water and lose ions
Reason: Freshwater animals tend to gain water by osmosis and lose ions by diffusion.
