Predict what will happen to the concentration of pyruvate, NADH and H+ when the Krebs cycle is stopped by arsenic.

Pyruvate would increase, NADH would decrease, and intermembrane H+ would decrease as well.

Explanation:

Pyruvate - Pyruvate was still made through Glycolysis, and it is not used in the Krebs Cycle, so it increased.

NADH - NADH was not made by the Krebs Cycle, this causes it to decrease.

Intermembrane H+ - The Electron Transport Chain would not be able to have the electrons needed to move the H+ since it does not have NADH, causing it to decrease.

answer; /// i do believe its (heredity); good luck

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
