In the thylakoids of the grana, light reactions take place and in the stroma , dark reaction takes place. So all in all, in both places together photosynthesis is carried out
        
             
        
        
        
The answer is A. Dew point is the temperature at which air will turn into water vapor, a state between gas and liquid. If the temperature is further cooled down to lower than the dew point, water will condense, in other words, the gas state of air will turn into liquid state of water.

Answer:
Principle of cross-cutting relationships
Explanation:
The geologic principle that will provide the most profound explanation to this problem is the principle of cross-cutting relationships. 
It states that "features that cross-cuts rocks are younger than the layer they cut through". 
Some of these features are intrusions, faults and joints. 
The logic behind this reasoning is that without the rock in place, the cross-cutting event wouldn't have been recorded. 
We can liken this to a fracture on the wall of a building. If the wall is not erected, there wouldn't be any fracture. Therefore, the fracture is far younger than the wall.
