The building blocks are amino acids
        
                    
             
        
        
        
Answer:
because it is hard to breakdown fat in a very short time while ATP can be broken down in a very short time.Fats have a very strong bond of molecular chains and this makes it hard to breakdown quickly
 
        
             
        
        
        
Answer: operon
Explanation:
An operon is a cluster of genes that are transcribed together to give a single messenger RNA (mRNA) molecule, which therefore encodes multiple proteins (Fig. 16.11). Such polycistronic mRNA is typically found in prokaryotes.
 
        
             
        
        
        
A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.
        
             
        
        
        
OK so for this one it is quite simple when we clear forests we basically take away an  insects habitat therefore  by clearing a forest for our personal use it will  have the greatest impact on the insects. So the best choice to go with will be option B.
