Answer 2

Analysis of the Statements:

I. Biological catalysts that can be used to obtain oxygen from hydrogen peroxide are obtained from raw potatoes or raw meat. II. Biological catalysts are destroyed when exposed to high temperatures.

Let's analyze each statement separately to determine if they are correct or incorrect.

Statement I:

The statement claims that biological catalysts used to obtain oxygen from hydrogen peroxide are obtained from raw potatoes or raw meat.

To verify this claim, I searched for information on biological catalysts used to obtain oxygen from hydrogen peroxide. According to my search results, the most commonly used biological catalyst for this purpose is an enzyme called catalase, which is found in various living organisms, including plants, animals, and microorganisms. Catalase is not specifically obtained from raw potatoes or raw meat, but rather from a variety of sources.

Therefore, Statement I is incorrect. Biological catalysts used to obtain oxygen from hydrogen peroxide are not specifically obtained from raw potatoes or raw meat.

Statement II:

The statement suggests that biological catalysts are destroyed when exposed to high temperatures.

To verify this claim, I searched for information on the stability of biological catalysts at high temperatures. According to my search results, it is true that high temperatures can denature or destroy the structure and function of biological catalysts, including enzymes. Enzymes are highly sensitive to temperature, and extreme heat can disrupt their active sites and render them non-functional.

Therefore, Statement II is correct. Biological catalysts can be destroyed when exposed to high temperatures.

In conclusion, Statement I is incorrect and Statement II is correct. Biological catalysts used to obtain oxygen from hydrogen peroxide are not specifically obtained from raw potatoes or raw meat, and biological catalysts can be destroyed when exposed to high temperatures.
