Question

Rate of heart beat in frog is

• A. 72 times per minute
• B. 75 times per minute
• C. 50 times per minute
• D. 64 times per minute

Answer 1

Answer: (D)

64 times per minute

In animals, rate of heart beat is connected with the size of animal. In mammals, smaller animals have higher heart beat. For example, 200 beats per minute in rabbit, 500 beats per minute in sparrow, 28 beats per minute in elephant. In frog, rate of heart beat is 64 per minute. In mammals, maximum heart beat is observed in shrew (800 per minute) and minimum in blue whale (25 per minute).

Therefore, the correct answer is option D.
