Biology Quizzes & Trivia

The is the terms as the building block of the human body, and they have outer coverings known as membranes that separate the interior parts of the cells from the outside one. It is through this membrane that lets some molecules in and out of the cell. Get to review chapter five from your raven biology on the cell membrane by taking up this test.
