Question

A zoology student is investigating whether it is true that the gender of turtles depends on the temperature at which the turtle eggs are kept before they hatch. He will test if turtle eggs incubated at 29–30 degrees Celsius produce females, and eggs at 24–26 degrees Celsius produce males. Which of them is the independent variable?
a. time
b. gender
c. species
d. temperature

Answer 1

I think the correct answer from the choices listed above is option D. The independent variable is the temperature. The dependent variable is the gender. The independent variable is the factor that is being varied and measured in the experiment so it must be the temperature.

Answer 2

D temperature is most likely your asnwer<span />
