<span>Increasing rates of work will increase the energy demand of the body. To fulfill the energy needs, the heart needs to pump more blood.
The rate of blood pumped by heart is known as cardiac output while stroke volume is the amount of blood pumped each contraction. It is calculated by: heart rate x stroke volume
The easiest variable to changed to increase the cardiac output would be heart rate. When a person increases his </span><span>rates of work, the heart rate will be increased to increases the cardiac output so the heart can supply the energy needed.</span><span>

A.) How tall the slope is
Answer:
Motor nerves
Explanation:
Pulling the leg quickly from the sharp object is an example of reflex action. It includes sensory receptors, sensory neurons, interneurons, the control center (spinal cord), motor neurons and effector.
As soon as she steps on the glass piece, the receptors present in the skin of her foot sole sense it and send the information to the control center via sensory neurons. The spinal cord commands the muscles of the effector organ (leg) via motor neurons to move to step away from the glass piece.
Pretty sure it would be the compound Magnesium.
Answer:
After six points of contact, fewer people were infected in Trial C than in Trial A. On average, the slope of the graph for Trial C was less than than the slope for Trial A. Infection spread at a slower rate in Trial C than in Trial A. In addition to the ten immune people, three nonimmune people did not become infected.
