Answer:
The answer is A. Evaporation of water due to warmer temperature causes low thick clouds. 
Explanation:
Evaporation is the process in which liquid is changed into gas due to increases temperature or pressure. It is an important part of water recycling in nature. water from sea, rivers and streams evaporate and form clouds which brings water back to earth by raining. Evaporation also causes cooling effect as during evaporation heat is absorbed from the environment. On the other hand the cloud formation and rain also induce cooling by bringing down the temperature. 
 
        
             
        
        
        
Answer: Option B 
Explanation:
The glucose is the basic unit of energy. It is absorbed by the cells of the body. The glucose that is taken inside the body by the means of food is utilized to gain energy.
The glucose that is absorbed from the food moves to interstitial spaces before going inside the cell. 
100% of the glucose is transferred from the interstitial spaces of the cell to the inside of the cell.
This is because more amount of the glucose is still outside the cell as it is absorbed completely.
