Answer:
Option (b) When dehydrated, a camel stores nitrogenous wastes in its tissues to conserve water.
Explanation:
The camel has good a hump on its back that helps with water storage. This is also made up of a water soluble fatty substance and fats. The water regulation is also controlled by the nephron which is an integral part of the kidney. The nephron has the Loop of Henle that regulates the retention of the water in the body. When there is no water, the potential of the ions force the water back into the kidneys so that the cells do not get disturbed. The nitrogenous wastes are expelled out as soon as possible because they form ammonium salts that may disturb the cell metabolism.
Hence, option (b) is not true.
