What happens to light after it strikes the retina?

Retina is made up of light sensitive cells. Those light sensitive cells are rods and cones. The rods and cons are responsible for vision at low level . they are two types of photo receptor. The rods are more sensitive then cons.     They are responsible for the detection of color and then  change  the  images into signals . The signals start traveling from brain to optic nerve.

i am positive it is c. condensing but i may be wrong

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.
