How do the products and reactants of a chemical change compare?

the mass of the products is greater than the mass of the reactants because energy is taken in by the reaction.

the mass of the products equals the mass of the reactants because the same matter is present.

the mass of the products equals the mass of the reactants because there is no energy involved in the reaction.

the mass of the products is less than the mass of the reactants because energy is given off by the reaction.

answer; i believe that the correct answer is ; males are hemizygous for the x chromosome;

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.
