What is the role of oxygen in cell respiration? What happens when oxygen is not present?
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.
What is the derivative of (x^2)^3?
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)
Solve for r. r^2=1
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.
