Question

In an experiment, the hypothesis is if the wavelength of the light shining on a plant is shortened, the rate of the photosynthesis is slowed Down. This hypothesis is_____

Testable
Falsifiable
Both of the above
None of the above

Answer 1

Hello!
The correct answer is C. We know this because a hypothesis can be both testable and able to be proven wrong (falsifiable).
I hope I helped!

Answer 2

Both of the above

Step-by-step explanation:

Falsifiable means that some observation might show it to be false. In this case, I can perform a test in which the wavelength of the light shining on a plant is shortened, and the rate of the photosynthesis is not slowed down; then, the hypothesis is falsifiable.

A testable hypothesis is a hypothesis that can be proved or disproved as a result of testing. Again, I can perform a test in which the wavelength of the light shining on a plant is shortened, and measure the rate of the photosynthesis; then, the hypothesis is testable.
