Question

State whether the following statements are true or false.
Smaller animals generally have a lower pulse rate than larger animals.

• A. True
• B. False

Answer 1

The correct option is B False

Smaller animals have much higher metabolism; proportionate to body size, smaller animals tend to have a much smaller heart than larger animals. This means that in order to circulate blood at the same rate, the hearts of smaller animals need to pump more times within a specified time because the volume they can pump each time is smaller.

So, the correct option is 'False'.
