How does the human body cope with an increased need for energy during exercise? a: it shuts downb: it decreses the heart ratec: it releases sweat to cool downd: it decreases the breathing rate

The correct answer is: it releases sweat to cool down.

During the exercise, body temperature increases and as a result respiration releases energy in the muscles, the skin produces sweat, which evaporates from the surface of the skin. Evaporation takes heat energy from the body.

Energy needed to perform exercise is derived from anaerobic metabolism within the cytosol of muscle cells (anaerobic respiration).

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.

primary succession begins with a bare rock and ends with a forest secondary succession begins after a natural disaster where there is a temporary setback after a forest fire or local destruction, but the surrounding area can fill in
