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 the same turtle species to different temperatures in a controlled laboratory experiment.

This lets the scientist control other variables, use replication and random assignment, and directly test whether temperature causes differences in sex ratios.
