Answer:
A mutation that cause changes to short stretches of nucleotides. These mutations affect the specific genes that provide instructions for various functional molecules, including protein . changes in these molecules can have impact on any number of an organism's physical characteristics 
 
        
                    
             
        
        
        
True 
DNA are cells that carry genetic codes and are passed down through generations of offspring. New cells can only arise from existing cells! 
        
             
        
        
        
Cellulose makes the cell walls of all plant cells. 
Option B
<h3><u>Explanation:</u></h3>
Enzymes are biomolecules that act as biocatalysts and to enhance the rate of a chemical reaction. Lipids and proteins make up the cell membrane bilayer. Cholesterol is a lipid molecule that comes under the category of very low density lipoprotein. Its not associated with storing the genetic information. The DNA stores the genetic information.
Glucose is the chief respiratory substrate of a cell. Its not associated with the increase in rate of a reaction. But cellulose is the molecule that is a polymer of glucose that is associated with the formation of cell walls in plants.
