Question
Chapter 33, Problem 4MCQ
Summary Introduction
Introduction:
The mechanism through which the concentration of ions in the body fluids is regulated is known as osmoregulation. The essential minerals, water, and ions are regulated by the mechanism and the mechanism is different in animals of different habitat.

Many types of fishes live in freshwater. Generally, water moves by osmosis from the surrounding fresh water into the fish's body. This observation helps to explain which feature of the excretory systems of freshwater fishes?
a. They tend to produce dilute, watery urine.
b. They tend to produce concentrated, dark urine.
c. They do not produce urine, but instead conserve or re-use nitrogenous wastes.
d. They may produce either dilute or concentrated urine, depending on the activity of the fish.
Birds that live in marine environments and thus lack access to fresh drinking water
A)obtain water by eating only osmoregulating prey.
B)osmoregulate without using a transport epithelium for this purpose.
C)drink seawater and secrete excess ions through their kidneys only.
D)drink seawater and secrete excess ions mainly through their nasal salt glands.
E)have plasma that is isoosmotic to ocean water.
Sharks live in marine (saltwater) habitats and are osmoconformers. Based on this information which of the following is/are true (select all that apply): A. Sharks have tissues/body fluids that are isoosmotic relative to the environment B. Sharks have tissues/body fluids that are hypoosmotic relative to the environment C. Sharks devote considerable energy to osmoregulation D. Sharks do not devote much energy to osmoregulation
