Carbon is the best answer while other elements can be sodium, Lithium, or sulfur. It combines with hydrogen easily, and is the basis for all fossil fuels and organic materials.
        
             
        
        
        
The object's mass. Weight would be how gravity affected it, size is how large it is, density is how tightly the molecules are to each other. Mass is how much matter is in the object.
        
             
        
        
        
Adenosine triphosphate (ATP) is a complex molecule which provides energy to the cells. This molecule is present in all the living organisms. The chemical energy which is obtained by the body by the breakdown of the food is captured by the ATP (Adenosine Triphosphate) molecules. This captured chemical energy is then transferred by it in order to fuel different body processes. 
Hence, the answer is ATP (Adenosine Triphosphate).
 
        
             
        
        
        
Answer:
A C B
Explanation:
Chlorophyll pigments absorb most of the light in the blue and red regions. Blue-violet region marks the peak absorption by chlorophyll a while chlorophyll b shows peak absorption in red blue light. Green colored light is not absorbed by chlorophyll a and b. Light absorption by chlorophyll is essential for the light-dependent phase of photosynthesis. Therefore the plant A grown under blue light will show maximum growth and plant B kept under green light would show minimum growth.
