Answer with Explanation:
Hydrogen peroxide is considered<em> "unstable,"</em> thus, storing it in the refrigerator provides two advantages:
1. It slows down thermal decomposition.
- The rate of decomposition slows down when the temperature is lowered. It increases when the temperature rises.
2. It prevents photolytic decomposition.
- Photolytic decomposition happens when hydrogen peroxide is exposed to sunlight or bright light. It therefore increases the rate of reaction. Therefore, hydrogen peroxide should be stored in a <em>cool and dark place</em>, such as the refrigerator.
Answer:
Your digestive system absorbs water and nutrients from the food you eat. Your circulatory system carries oxygen, water, and nutrients to cells throughout your body. Wastes from the cells are eliminated by your respiratory system, your excretory system, and your skin.

Photosphere,chromosphere and the corona
Answer: Pteridophyte
You classify the plant as a pteridophyte
Explanation:
Pteridophytes are known to have the following:
- many cells (multicellular) and vascular bundles
- true roots, stems, and leaves
- do not produce flower throughout their lifespan
- they are mainly terrestrial plants, while few are aquatic
- do not produce seeds but reproduce asexually by formation of spores
Examples are ferns
