Explanation: The plasma membrane is a membrane the protects the cell and its environment. It regulates what goes inside and what comes out of the cell. .
Plasma membrane as a structure composed of multiple components, including phospholipid bilayer, carbohydrates, and other lipids. The phospholipids possess one head and two tails. The head is basically polar and hydrophilic (water-loving) while the tails are non-polar and hydrophobic (water-fearing).
The plasma membrane is decorated with proteins. Some protiens are extrinsic proteins that run halfway through the membrane, while others are called integral proteins that go entirely through the membrane. The function of these proteins is to serve as channels to allow the molecules to enter and leave the cell.
A buffer is a solution encompassing a weak acid and its conjugate base in alike amounts. This combination reduces the pH change upon addition of strong acid or base by converting H1+ (or OH1-) to weaker acids or bases. This primarily consist of compounds that stabilize the pH of a solution by removing or replacing hydrogen ions. Also, substances that resist change in pH.
Sickel cell anemia is an inherited disease that is due to a base substitution mutation in a gene.
