Choose the incorrect statement with reference to Kangaroo rat.
- eliminates dilute urine.
- found in North America desert.
- meets its water requirements through internal fat oxidation.
- uses minimal water to remove execretory products.
The Correct Option is A
Approach Solution - 1
Kangaroo rats are specially adapted to desert environments where water is scarce.
- (A) eliminates dilute urine: This statement is incorrect. Kangaroo rats are adapted to conserve water and produce highly concentrated urine, not dilute urine. This allows them to retain as much water as possible.
- (B) found in North American desert: This statement is correct. Kangaroo rats are found in the deserts of North America, particularly in arid regions like the southwestern United States.
- (C) meets its water requirements through internal fat oxidation: This is correct. Kangaroo rats can obtain water by metabolizing their body fat, a process known as internal fat oxidation.
- (D) uses minimal water to remove excretory products: This is correct. Kangaroo rats excrete very little water when eliminating waste, further conserving water.
Thus, the incorrect statement is (A) eliminates dilute urine.
The correct answer is (A) : eliminates dilute urine.
Approach Solution -2
The correct answer is: (A) eliminates dilute urine.
The Kangaroo rat (Dipodomys) is a small nocturnal rodent native to North America, well adapted to desert life. It has several unique physiological and behavioral adaptations that allow it to survive in arid environments where water is scarce.
One of the key adaptations of the Kangaroo rat is its ability to conserve water. Instead of producing large amounts of dilute urine like many other animals, the Kangaroo rat produces highly concentrated urine. This minimizes water loss, allowing the animal to retain moisture in its body even in the absence of external water sources.
Therefore, the statement in option (A), which suggests that the Kangaroo rat eliminates dilute urine, is incorrect. In reality, the Kangaroo rat produces highly concentrated urine to conserve water.
