Ascientific study looked at the effect of tanning beds on dna damage. the scientists took skin cells and exposed them to uv radiation (the type used in indoor tanning beds) for different lengths of time: some for 1 minute, some for 5 minutes, some for 15 minutes, and some for 30 minutes. they then looked for signs of dna damage and compared the results to cells that had never been exposed to uv light. what is the independent variable in this experiment

Tanning of DNA using UV light at different time (1 minutes, 15 minutes, and 30 minutes)

Explanation:

Independent variable is the variable that was controlled or change and in this case it is the tanning of DNA with UV light at different times and the dependent variable is what is measured or the effect of the change in the independent variable which is DNA damage and the control was the cells that did not receive the treatment.

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.
