Anne has a sample of a substance. its volume is 20 cm3, and its mass is 100 grams. what is the sample’s density?

The correct answer would be 5 grams per centimeter cube.

Density is defined as the mass of a substance present in a unit volume space.

It is represented by ρ (rho).

It can be calculated by dividing mass of a substance with its volume.

Thus, density of a substance Anne has would be = 100/20 which comes out to be 5 grams per centimeter cube

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.
