Answer:
15%
Together, adenine and thymine compose 70% of the segment. This means that 30% of the section is composed of guanine-cytosine pairs. Since these two bases will be equal in quantity, 15% of the DNA section will be cytosine bases.
 
        
             
        
        
        
Proteins
Enzymes are proteins that can lower activation energy of reactions in the body (I think).
        
             
        
        
        
Do you have the options? lol
        
                    
             
        
        
        
 • Matthias Schleiden observed that all plants were made of cells; Theodor Schwann observed that all animals were also made of cells; and Rudolf Virchow observed that cells only come from other cells.
• Prokaryotic cells- don’t contain a nucleus or any other membrane-bound organelle. 
 Eukaryotic cells- contain membrane-bound organelles, including a nucleus. 
• Phospholipids make up the basic structure of a cell membrane and are arranged in a double layer called the lipid bilayer.
• Active Transport- moves ions from low concentration to high, using metabolic energy in the form of ATP.
 Passive Transport - moves ions from high concentration to low, using no metabolic energy.
