The correct Answer is:
To solve the question regarding the statements about frogs, we will analyze each statement one by one to determine their accuracy. ### Step-by-Step Solution: 1. **Statement 1: Frog never drinks water but absorbs water through its skin.** - This statement is **correct**. Frogs do not have a drinking mechanism like mammals; instead, they absorb water through their permeable skin, which allows them to take in moisture directly from their environment. 2. **Statement 2: Hind limbs of frog end in four digits.** - This statement is **incorrect**. Frogs have hind limbs that typically end in **three digits** (toes), not four. This is a distinguishing feature of their anatomy. 3. **Statement 3: Male frogs have vocal sacs.** - This statement is **correct**. Male frogs possess vocal sacs, which are important for producing calls to attract females during mating season. This is a characteristic feature that differentiates them from female frogs. 4. **Statement 4: Male frogs have a copulatory pad on the second digit of the forelimb.** - This statement is **incorrect**. Male frogs do have a copulatory pad, but it is located on the **first digit** of the forelimb, not the second. This pad helps them grasp the female during mating. 5. **Statement 5: Frog has a bilobed tongue.** - This statement is **correct**. Frogs have a bilobed (two-lobed) tongue that is sticky and aids in capturing prey. This unique tongue structure is an adaptation for their feeding habits. ### Summary of Correct Statements: - Correct statements: 1, 3, and 5. - Incorrect statements: 2 and 4. ### Final Answer: The correct statements regarding frogs are 1, 3, and 5. ---
