Solution X was placed in a bag made of a selectively permeable dialysis membrane. The bag was securely tied, rinsed off with distilled water, and then suspended within a large
beaker of distilled water, as shown above. The contents of the bag and the beaker were
tested for presence of sugar, starch, lipid, and protein at the start of the experiment
and 24 hours later. The volume of the bag increased during this time. The results of
these tests are presented in the table below.

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.
