The correct answer is active hyperemia.
Active hyperemia represents the increase in organ blood flow (hyperemia) that is associated with the increased metabolic activity of that organ. In this case, the increase in blood flow accompanies muscle contraction during the exercise. Muscle contraction stimulates the production of vasoactive (vasodilative) substances that dilate the vessels and thus, bring more oxygen to the muscles.
Answer:
The burning of fossil fuels produces gases like sulfur dioxide and carbon dioxide which trap the sun's heat radiations and increase the overall temperature of the Earth. So the answers are A & B.
Explanation:
Global warming is caused by burning fossil fuels. The <em>carbon dioxide </em>produced as a result captures the heat in the surrounding atmosphere and causes a <u>rise in temperature</u>. Recently, it has been observed that the glaciers are melting and each year the net temperature of the core of the Earth is <em>increasing</em>.
The other gas produced is sulphur dioxide which is responsible for the acid rain. The sulphur dioxide combines with water to form sulphuric acid which causes damage to buildings and people. E.g Taj Mahal, in India is getting corroded by acid rain.
