Answer:
4. The correct pathway for the flow of electron during photosynthesis is mentioned in option D.  > <em>NADP </em>> <em>Calvin cycle.</em>
 > <em>NADP </em>> <em>Calvin cycle.</em>
- Electron is first provided to the photo-system II by the phtolysis of water. 
- Then it is passed to photo-system I with the help of plastoquinone (PQ) and cytochrome  . .
- Finally, electron from the photo-system II is used to reduce NADP to NADPH.
- NADPH and ATP are used in light independent phase or Calvin cycle to synthesize carbohydrate from carbon dioxide.
5. The correct answer is B.) photosynthesis.
- Photosynthesis is the process by which green plants synthesize glucose or carbohydrate from carbon dioxide and water in presence of sunlight and chlorophyll.
- In light independent phase of photosynthesis, it requires ATP and NADPH  in order to synthesize food.
- Lastly, oxidation or breaking down of glucose releases energy and photosynthesis is a anabolic process instead of catabolic one.  
 
        
                    
             
        
        
        
Answer:
True 
Explanation:
The stratosphere is the layer of the earth’s atmosphere which is above the troposphere and below the mesosphere.
The stratosphere contains about 90 percent of the ozone layer. The stratosphere is made up of ozone layers which helps in the absorption of about 95 percent of the ultraviolet rays from the sun and converting to heat. 
This is the reason why depletion of the ozone layer found in the stratosphere gives rise to global warming.

Answer:
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
