A scientist hypothesizes that temperature affects the gender of a species of turtle. How can the scientist test this hypothesis?


by exposing different turtle species to the same temperature in a laboratory


by exposing different groups of turtles to different sets of temperatures in a laboratory


by observing a group of the turtles in the wild


by using a computer to model turtle behavior

by exposing different groups of turtles to different sets of temperatures in a laboratory

Ans.

In some organisms, such as crocodiles, lizards, and turtles, gender determination is affected by temperature. In turtles, the eggs become female  when the temperature is higher, while eggs become male when temperature is less than that of required by female development.

Thus, to hypothesizes that the gender determination in turtles is affected by temperature, 'the scientist should expose different groups of turtles to different sets of temperatures in a laboratory.'
