If a toxin blocked an organisms ability to undergo transcription, what else would the cell not be able to do ?

The cell would be unable to create proteins

Explanation:

Transcription is the process by the DNA is read by RNA polymerase to create mRNA. The mRNA is then used by ribosomes to create proteins by recruiting respective amino acids that correspond to the codon sequence on the mRNA (in a process called translation).  

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.
