Answer; 
 The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2. 
Explanation; 
-Photosynthesis is the process by which green plants use light energy from the sun, water and carbon dioxide to make organic molecules, such as simple sugars. 
-The process takes place in two phases; light dependent stage and light independent stage. 
-During light dependent stage light energy is used to break down water molecules into hydrogen ions and oxygen atoms. 
-Light independent reactions uses CO2 and the ATP and NADPH from light dependent reactions to produce sugar/ glucose. ATP is used to provide the energy for sugar synthesis and NADPH is used for electrons in the reduction of Carbon Dioxide into sugar.
 
        
                    
             
        
        
        
Answer:

The amino acids are the building blocks of the proteins.  
Explanation:
The amino acids are the organic molecules made up of a carboxylic group, an amino group and a carbon side chain. The proteins are macromolecules, made up of amino acids. Many amino acids combine to form a protein. The structure of the protein depends on the sequence of the amino acids present in the structure of protein. A different protein has a different sequence of amino acids.  
 
        
                    
             
        
        
        
Natural selection, if only the best make it the gene pool will have stronger sheep and those sheep breeding will cause even stronger sheep
