Question

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

Answer 1

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

Answer 2

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.'
