Question

1. what are two jobs of the cell membrane? choose 2 * 3 points store and release energy protect the cell allow materials to enter and leave the cell make and store proteins

Explanation:

1. Analyze each option:

• "store and release energy": This is the job of structures like mitochondria (energy release) and maybe storage molecules, not the cell membrane.
• "protect the cell": The cell membrane acts as a barrier, protecting the cell from its surroundings.
• "allow materials to enter and leave the cell": The cell membrane is selectively permeable, regulating the movement of substances in and out of the cell.
• "make and store proteins": Ribosomes make proteins, and storage of proteins is not a main job of the cell membrane.

1. So the two correct options are the ones related to protection and regulating material movement.

Answer:

B. protect the cell, C. allow materials to enter and leave the cell
