Wich organelle converts the chemical energy stored in food into compounds that are more convenient for the cell to use a. chloroplast b. golbgi apparatus c. endoplasmic recticulum d. mitochondrion

Correct answer is D: mitochondrion

Explanation:

In mitochondrion respiration takes place.  

In this process, that occurs in presence of oxygen, energy is obtained from pyruvate. Glucose is a key product from food and has chemical energy stored. Pyruvate comes from glucose degradation in cytosol and gets into the mitochondrion. There, it is degraded and electrons are transported from a membrane protein to another one until they reach the oxygen and form H2O. While this occurs, a H+ (proton) gradient is generated at both sides of the internal mitochondrion membrane and this potential is finally used to synthesize ATP (available energy for the cell).  

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.

the answer is: reproductively

i think i spelled it wrong lol

anyways hope i
