Okay there are 2 questions and their both true or false 1. Transmission occurs when light rays strike a material and pass through it.
2. Scattering occurs when a material emits light, and then re-emits the light in different directions. thxxx so much :(​

when it's short and dry.

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.

answer: dna

because all cells have genes
