The cell wall maintains the integrity of the cell. The cell wall helps protect the cell against the environmental changes it it allows most molecules to pass through it. This layer is composed of molecules called peptidoglycans. Just inside the cell wall is a less rigid envelope called the plasma membrane also known as the cytoplasmic membrane. In bacterial cells the plasma membrane has two primary functions: it serves as a selective barrier to molecules that are penetrating the cell wall allowing

Action Potentials An action potential is the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell. An action potential occurs when a neuron sends information down an axon‚ away from the cell body. A threshold is the minimum amount of stimulation needed to start a neural impulse (you know‚ the electrical impulses that travel throughout your body carrying important information). Action potentials generated by neural impulses are

Question #1: A. Explain why tearing paper is an example of a physical change and not a chemical change. Physical change is a change in shape. Chemical change is when a product changes into a completely different thing because of a reorganization of molecules. When you tear paper‚ the paper does not turn into something else; it is still paper. Does‚ tearing paper is an example of physical change. B. Explain why burning a piece of paper is an example of a chemical change and not a physical change. When you
