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:
The correct answer is - urea.
Explanation:
In our body, to produce energy or produce glucose our body breaks the amino acids, it gets from proteins mainly. These amino acids are mainly breakdown into amine groups.
The human body has a unique ability to pack ammonia(amine group) by converting it to urea and incorporated and produced by the liver using 2 molecules of ammonia (NH3) and 1 molecule of carbon dioxide (CO2). This incorporated urea is then secreted from the liver and incorporated into the urine in the kidney for further process.
During the lifecycle of the plant we can encounter both haploid and diploid forms.Haploid form of the plant is called a gametophyte. This form was created from spore and enables creation of haploid gametes in the next stage.
