Proteins, carbohydrates, and lipids (including cholesterol and phospholipids) make up the majority of the plasma membrane. Intracellular components are shielded from the extracellular environment by the plasma membrane. The materials that enter and leave the cell are controlled by the plasma membrane, which mediates cellular functions. All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane. Lipids (phospholipids and cholesterol), proteins, and carbohydrates make up the majority of the plasma membrane. The extracellular environment is shielded from intracellular components by the plasma membrane. By controlling the substances that enter and leave the cell, the plasma membrane facilitates biological processes. All cells contain a membrane that divides the interior from the external environment. This membrane is known as the cell membrane or the plasma membrane. A lipid bilayer that is semipermeable makes up the cell membrane. The cell membrane controls the movement of materials into and out of the cell.

Answer:
B. The part of an aquifer where surface water reaches the water table
Explanation:
The recharge area of an aquifer, is the area where the aquifer comes in touch with the surface water. At this area, the aquifer is receiving new and fresh water reserves from the surface, thus replenishing the water that it has lost. Most of this water comes from the rainfall and runoff, though rivers and streams can also contribute to it. The recharging of the aquifer is crucial for its existence, as it constantly loses water, and the recharging in giving back water to it, thus balancing the lost and gained water in it.
Answer:
Sister chromatids.
Explanation:
Sister chromatids are the two identical halves of a chromosome that are held together at centromere with help of cohesin. DNA replication in the S phase of the cell cycle doubles the amount of DNA. The copies of the DNA formed during DNA replication are accommodated in sister chromatids. Hence, two sister chromatids of a chromosome carry the identical DNA helices and associated proteins.
