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. 
 
        
             
        
        
        
She should have to classify this animal under pseudocoelomates category. The body cavity of these animals are filled with fluids. Internal organs are covered by the fluid filled space. The body cavity serves as the hydrostatic skeleton and have other functions such as digestion of food and waste removal.

Answer:
Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil. Mosses can then colonize the thin soil; as mosses die, the soil thickens more allowing other hardy species to colonize

Answer:
37
Explanation:
Since the Gruffalo has a somatic chromosome number of 67 and the Buffalo has a somatic chromosome number of 60, we may infer that seven chromosomes from the Grizzly were not able to pair up with the chromosomes of the Buffalo. Checking the options, the only choice that has a suitable number is b. 37 chromosomes. If this is true, then the remaining 30 chromosomes were able to pair up.
