Resistance depends on there properties of a wire: - length (the longer the more resistance) - area (the less area = more resistance and vise verse more area = less resistance) - resistivity (the more resistivity the resistance)
The answer is a. The arteries are red and transfer blood to the heart. Veins are blue and transfer blood away from the heart and to all of the different parts of the body. The capillaries are in-between the veins and arteries and provide blood to cells.
