2 Mitochondria are important organelles of cell often called powerhouse of the cell Why?
3 Why do kabaddi players rub their hands with soil?
+ Can microorganism be seen with the naked eyes if not how can they be seen?
5 Why are bells made of metals?
6 Why big vehicles have large tyres?
​

Answer 1

Answer:

1. There were no nerves present in nail and hair.

2. Mitochondria are powerhouse of cell because they produce energy compounds like ATP (Adinosine Triphosphate)

3. Kabaddi players rub their hand with soil in order to increase their friction in hand.

4. Microrganisms can't be seen with naked eye, they can be seen with the help of microscope.

5. Bells are made up of metals because metals are sonorous in nature.

6. Big vehicles have large tyres to reduce their pressure on the surface

HOPE IT HELPS :)

Answer 2

Explanation:

1. because they are growing parts of the body but if we cut them by root it hurts

2. Mitochondria work as the powerhouse of the cell as it provides the energy to cell in the form of ATP

3.Kabaddi players rub their hand with soil so they gain the heat

4. No they cannot be seen by naked eyes only one microbe can be seen by naked eyes named thiomargrita nemibensis and all other. microbes can be seen by naked eyes

5. Bells are made up of metal because metal produces a pop sound

6. because of they have small tyres they produce more pressure and less force hence the force exerts on Tyre cannot be larger force then friction .
