Answer:
El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds. La Niña is the opposite – a cooling phase of ENSO that tends to have global climate impacts opposite to those of it. El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.

<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>
