<span>Buffers.
Buffers are chemicals that maintain pH at a very specific range. This is because buffers have an equilibrium that they will maintain that is very stable. If there are too many hydrogen ions (acidic), then buffers will sweep them up and hold onto them. If there are not enough ions in the matrix (basic) then the buffers will release the hydrogen ions and maintain a stable pH.</span>
        
             
        
        
        
Answer:
Input- Carbon dioxide, Water, Sunlight.

The correct answer is that bones do not have a role in glycogen production. Glycogen is only produced by two organs of the body; the muscles and the liver. Bones and bone structures function to support movement by serving as insertions for the muscles. The tissue inside the bone is called the bone marrow; which is divided into red marrow (functions for blood cell formation) and yellow marrow (functions to store fat).

• Genes can contain more than one polyadenylation site, which alters the 3' of the mRNA transcript and the inclusion/exclusion of exons. 
• mRNA transcripts from the same gene can be differentially spliced to include/exclude exons.
