Ultraviolet light will increase on earth's surface. It will "raise" temperatures and decrease plant populations.
Actually UV rays do not increase temperature, that's wrong.
They cause mutations in several organisms as they modify their DNA. They also cause skin cancer in humans and also cataracts and sunburns.
But they don't increase temperature.
That's carbon dioxide accumulation.
It is known as the liver.
The correct answer is sympathetic nervous system.
In the given case, the harry is experiencing stress, which provokes the flight and fight syndrome. The sympathetic nervous system causes the release of adrenaline and noradrenaline causing change in physiological responses. During the flight and fight response, a hyperarousal occurs, which leads to the change in physiological responses. It causes the increased heart beat, increased blood pressure, anxiety, increase in pulse, increased sweating etc.
