To effectively test the hypothesis that temperature affects the gender of a species of turtle, the scientist should use the method of **by exposing different groups of turtles to different sets of temperatures in a laboratory**.
This experimental design allows for controlled conditions where the scientist can isolate temperature as the variable and systematically observe any resulting changes in the gender distribution of the turtles. The use of different temperature sets enables the scientist to determine if specific temperature ranges influence the gender of the offspring.
The other options have limitations:
- Exposing different turtle species to the same temperature may not provide insight into the specific species being studied.
- Observing turtles in the wild introduces many uncontrolled variables that could affect gender outcomes, making it difficult to draw clear conclusions about the impact of temperature.
- Using a computer model does not provide direct empirical evidence and may rely on assumptions that may or may not accurately represent real-world conditions.
Thus, the most effective approach to test the hypothesis is through controlled laboratory experimentation.
