Answer:
a) Greenhouse Effect.

a) The Greenhouse Effect is one general effect of overuse of an environmental resource. Through this effect Earth's surface is warmed, destabilising environmental temperature. This effect is caused by the hydrocarbons overexploitation.
b) Nuclear Energy could be an option to decrease the hydrocarbons overexploitation. Even tough, nuclear energy doesn't produce that much greenhouse gases, that's why is an option that some governments are considering.
c) The earthquake that happened in Easter Island could be an indicative of environmental issues, because the greenhouse effect can produce earthquakes, due to the elevation of the Earth temperature, icebergs are melting in the Earth Poles, causing a bump effect in the Earth crust.
Insulin helps control blood glucose levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.
