Explain each of these reasons why.It was a “bridge” Proximity to the Mediterranean SeaVariety in elevationFloodplainDefine agriculture:What was the role of plowing?What was the role of artificial selection?What impact did agriculture have on the human population?What growth-limiting factors were removed?What change took place during the Industrial Revolution?Describe each medical discovery made during the Industrial Revolution.Germ Theory –Vaccines –Antibiotics –Water Treatment –The human population grew at a fixed rate before the industrial revolution. What does this mean?The human population grew at an exponential rate after the industrial revolution. What does that mean?Label fixed growth, exponential growth, and the Industrial Revolution on the human population graph.Give the formula for calculating doubling time.
