<h3>A) Enzymes are highly specific protein catalysts</h3>
Explanation:
- Enzymes are highly specific protein catalysts i.e. it react with only that substrate for which it has been made.
- Enzymes have an active site by which it binds to substrate at that specific site.
- Enzymes lowers the activation energy required for completion of a chemical reaction. As a result rate of the reaction increases.
- Enzymes never participate in a chemical reaction rather they are obtained back in its original form on the completion of the reaction.
Global warming and Global cooling. As the Earth's orbit becomes more elliptical, (as it is now,) it begins a Global warming and enters into an Interglacial period, when the Earth is mostly warm. When the Earth's orbit becomes more circular around the sun, (as it has been at least two or three times before so far,) it begins a Global cooling and enters into a Glacial period. I hope that this helps!

Hair cells are present inside the inner ear that acts as a receptor of sound. Researchers affirmed that once there is a damage to the hair cell, it can regenerate in birds.
Damage hair cell can lead to loud noise which in turn affect the ear. The supporting cells are present along with the hair cells. When the hair cells get damaged, the supporting hair cell gets the signal to start the process of regeneration.
