In the picture, the organelle depicted is a

a) Chloroplast

Explanation:

Since the figure shows an organism by an envelope formed by two concentric membranes containing vesicles called thylakoids, where they are organized pigments and other molecules that convert light energy into chemical energy, such as chlorophyll.

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.
