how do whales and dolphins breathe

🤔 How it works ……..

HOW DOES WHALES AND DOLPHINS BREATHE ⁉️ 🐳🐬

Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. They breathe through nostrils, called a blowhole, located right on top of their heads.

This allows them to take breaths by exposing just the top of their heads to the air while they are swimming or resting under the water. After each breath, the blowhole is sealed tightly by strong muscles that surround it, so that water cannot get into the whale or dolphin’s lungs. When a dolphin surfaces for air, he breathes out (exhales) first and then breathes in (inhales) fresh air; it only takes a fraction of a second for the dolphin to do this.

They have high amounts of haemoglobin and myoglobin to store oxygen in their blood and muscles, can reduce their heart rate and even shut down some organs when they dive to help them survive in the deep

😳Why❓❓❓

Why does distilled water not conduct electricity where as rain water does?

Distilled water is the pure form of water. It is neutral in nature and also it doesn’t dissociate into ions and it has negligible ionization.

Electricity needs ions to move in an electrolyte, which is not provided by water.

Rain water on the other hand, contains dissolved salts, acids and even few basic particles. These particles dissociate in water into ions which help in conduction of electricity.
So, Rain water conduct electricity.
