Question:

What is the role of oxygen in cell respiration? What happens when oxygen is not present?

Lauren S.

Answer:

Oxygen allows Carbon Dioxide to form due to the citric acid cycle and strips the H+, transfers it to NAD+, forming NADH . When oxygen is not present, the lack of O2 causes anaerobic harvest of food energy through fermentation, promoting the buildup of lactic acid and only produces 2 ATP.

Question:

What is the derivative of (x^2)^3?

Lauren S.

Answer:

the answer is 6x(x^2)^2. due to the chain rule ( d/dx f(g(x))= f'(g(x)) (g'(x)) ), we must take the derivative of the outside part( 3(x^2)^2 ) and multiply it by the derivative of the inside (2x)

Question:

Solve for r. r^2=1

Lauren S.

Answer:

r=1,-1 since r is squared, you can take the square root of both sides. You receive both a positive and negative answer because the r^2 will always result in a positive number, regardless of the sign in front of the number plugged in.
