Question

The biological adaptation that allows frogs to obtain water for their survival during conditions of water scarcity is the

• A. Presence of modified tongue that acts like a sponge to suck water from damp soils
• B. Presence of water channels in the skin by which they absorb water from their surroundings
• C. Presence of ciliated oesophagus that helps in separating water from ingested particular matter
• D. Selective feeding on plants with large amount of water that would fulfill the water requirement

Answer 1

The correct option is B Presence of water channels in the skin by which they absorb water from their surroundings

In the conditions of water scarcity, the frogs show biological adaptation to reduce water loss or obtain water from the surroundings. The skin is modified to contain water channels. The water is absorbed from the surroundings through the skin and the water channels makes the water available for the survival.

Thus, the correct answer is option B.
