Phosphate buffer is a buffer used in many types of reactions with the function to maintain constant pH value.
This is important because enzymes’ activity is affected by changes in pH. There is an optimum pH for every enzyme that can be defined as most favorable pH value or the point where the enzyme is most active. Phosphate buffer is often use in the measurement of enzyme’s activity because it is isotonic and non-toxic to most cells.

Explanation: is correct
Answer: A) Abrasion
Explanation: Abrasion is the process of wearing away a surface by friction.
Lipids are apart of the cell membrane and they are known as phospholipids becuase they have both a polar and an nonpolar side.
The head is polar
and the body is nonpolar. This keeps the outside of the cell and the cell differentiated.
the phospholids tails (the non-polar part) are unsaturdated fattty acids.
Unsaturdated fatty acids are chains that are not straights and are slightly bent(kinks) This allows for the cell membrane layer to be fluid
Ribosomes make up the proteins within the cell.
