What are the most important characteristics of an enzyme?

Enzymes speed up reactions by bringing reactants together and reducing the activation energy required to start the reaction (enzymatic reaction). Enzymes are specific: they have a specific shape, therefore only a certain substrate will fit its active site.

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 c. it will give up it's valence electron to the other atom.
