Which of the following in freshwater fish helps combat the problem of living in fresh water (osmoregulation)?
-
Dinking much water
-
Producing concentrated urine
-
Producing large quantities of urine
-
Excretion of salt ions from gills
Homework Answers
Please find the answer below:
Answer: Producing large quantities of urine
Explanation: Freshwater fish living in freshwater have a higher concentration of salt in their bodies. Lots of water from the freshwaters enter the fish but these fish remove them through large quantities of urine. They maintain their salinity by the use of numerous glomeruli that help to filter blood and retain salt.

Which of the following statements about osmoregulation are NOT true? Select one: a. Osmoregulators can control their internal osmolarity independent of external environment and thus maintain a constant osmotic pressure in the blood b.

2. *D1* Salt water is plentiful on earth; natural supplies of fresh water, on the other hand, are dwindling while mankind's demands grow. One appealing solution to this imbalance is to remove the salt from ocean water by some means. Here you will investigate the energy input that is necessary to accomplish this task. Special membranes can be manufactured that allow water, but not ions, to pass through. By pushing such a membrane through salt solution, one can separate salt...

1. a. Which of the following statements about the Thermoneutral Zone (TNZ) is TRUE? The TNZ is when the animals body temperature is the lowest. Animals need to eat the least amount of food in their TNZ. Both endotherms and ectotherms have a TNZ. This is the environmental temperature where the animal can move the fastest. Animals need to increase their metabolism to maintain their TNZ. b) Marine osmoregulators perform which of the following processes to survive in a salt-water...
