The following chart lists taxonomy classifications for seven organisms. Some have just one classification, while others have a subclassification. Which four classifications best match the classifications of your fossils? Research the classifications if you don’t know their characteristics.

true is the answer : )

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.

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.
