Explain how the structure and function of the smooth muscle, skeletal muscle and cardiac muscle is required for its function in the body.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

the answer is "a.) well–developed vascular system."

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.
