Which statements accurately describe the cell membrane? Select all that apply. - It selectively permits certain materials to exit the cell. - It allows only specific materials to enter the cell. - It aids the cell in expelling waste. - It does not allow all materials to enter or leave the cell. - It does not import waste into the cell for storage.

 It selectively permits certain materials to exit the cell: This statement is accurate as the cell membrane controls the exit of various substances from the cell, including waste products and secretions.

- It allows only specific materials to enter the cell: This statement is true. The cell membrane is selectively permeable, meaning that it allows certain molecules and ions to pass in and out while preventing others.

- It aids the cell in expelling waste: This is an accurate description of one of the functions of the cell membrane. It enables the cell to get rid of waste materials through processes like exocytosis.

- It does not allow all materials to enter or leave the cell: This is a correct statement. The cell membrane's selectivity ensures that essential molecules such as nutrients can enter, while harmful substances are kept out, and waste can be expelled.

- It does not import waste into the cell for storage: This is also accurate. Generally, the cell membrane does not bring waste products into the cell; its primary function is to clear waste and maintain homeostasis, not to store waste.
