Question

In a controlled experiment designed to study the effect of a certain gene mutation on the color of flower petals, researchers grow plants with and without the mutation under identical environmental conditions. However, halfway through the experiment, the temperature control system in the growth chamber malfunctions and causes a significant temperature drop for all plants. What is the likely consequence of this malfunction?

Options

The experiment's results will be more accurate as the plants experienced a natural stressor.

The experiment is invalidated because the temperature, a confounding variable, was not properly controlled.

The researchers can still draw valid conclusions as long as they note the temperature change in the report.

Only the plants without the mutation will be affected, so partial results can still be used.
