B: destroying infectious germs
C: responding to external stimuli
D: obtaining moisture from the air

c

Explanation: The plant is responding to external stimuli by growing toward light like our eyes adjusting to the light in the dark

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.

b. read the phase at the intersection of any given temperature and pressure.
