Worked Solution & Example Answer:A biologist studied the concentration of urine produced by a terrestrial mammal, a freshwater fish and a marine fish - HSC - SSCE Biology - Question 7 - 2002 - Paper 1
Step 1
Produces dilute urine
Answer
Terrestrial mammals tend to produce concentrated urine to conserve water due to their land environment, while freshwater fish produce dilute urine due to their environment's high water content. Marine fish, which live in a saline environment, also typically produce concentrated urine to prevent water loss. Therefore, option (D) is the correct choice, which states:
- Terrestrial mammal: Produces concentrated urine
- Freshwater fish: Produces dilute urine
- Marine fish: Produces concentrated urine.
