10. The cell membrane is? A permeable. B. semi-permeable
C. impenetrable

Semi-Permeable

Explanation:

This is due to the reason that cell membranes require water and other nutrients to enter the cell and waste to exit the cell in order for it to function properly. If the cell membrane were permeable, anything would be able to enter including harmful microbes. If the cell membrane were impenetrable, the cell would die as it would not be able to receive the nutrients and materials needs.

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.

the answer is: metamorphic rocks often show the presence of fossils, also a
