Question

Blowholes in whales are similar in function to the human _____.

• A. heart
• B. gills
• C. ear
• D. nose

Answer 1

The correct option is D nose

Whales cannot absorb the dissolved oxygen in water and they have to keep coming to the water surface at regular intervals to breathe, i.e., to inhale and exhale.
To fulfil this function, whales have blowholes that are similar to nostrils which are located on the top or back of their head.
