What is a type of so without a membrane bound and useless and without membrane-bound organelles A. Eukaryotic cell
B. Plant cell
C. Elements
D. Prokaryotic cells

Prokaryotic cells don't have a membrane bound organelle

Explanation:

Prokaryotic cells has no nucleus as well as no membrane bound organelle. To remeber this, Pro rhymes with NO. Meaning NO nucleus NO membrane but it do have ribosomes,cytoplasm, and etc.

This is the answer if thats what you are reffering too.

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.
