Question

The human heartbeat is about 70 times per minute. The approximate rate of heartbeat in an elephant & a mouse is respectively;

• A. 500 & 35 /min
• B. 35 & 500 /min
• C. 100 & 60 /min
• D. 60 & 100 /min

Answer 1

The correct option is B

35 & 500 /min

The correct option is (C):

Explanation of the correct option:

1. The walls of the muscular heart contract and relax rhythmically and this rhythmic contraction and relaxation of the heart constitutes the heartbeat.
2. One heartbeat is responsible for generating one pulse of the arteries. The pulse rate per minute indicates the rate of heartbeat.
3. In human beings the pulse rate is around 72 beats per minute.
4. The pulse rate (heartbeat per minute) of an elephant is approximately 30 to 35 beats per minute.
5. However, the pulse rate of mice is more. It is around 500 to 700 beats per minute.

Final answer:

The approximate rate of heartbeat in an elephant & a mouse is 35 & 500 /min respectively.
