Question

Consider the following hypothesis:

Soil type affects the germination of radish seeds.

Which of these should the experiment do in order to best test this hypothesis?

A.
Measure the rate at which radish plants grow after their seeds germinate

B.
Measure the average depth at which germinating radish seeds were planted

C.
Compare the percentages of radish seeds that germinate in different types of soil

D.
Compare the average numbers of radish seeds that germinate in different states

Answer 1

Answer:

C

Explanation:

You are testing the affects of different soils on the germination of seeds, therefore, you must compare different types of soil. The other answers don't have correlation to different types of soils, and are incorrect.

Answer 2

Answer: C. Compare the percentages of radish seeds that germinate in different types of soil

Explanation:

The hypothesis you are trying to prove is that the soil type affects the germination of radish seeds, to do this you would need to compare the germination rates of radish seeds in different soil types to see if there is an actual difference on the germination rates of the seed.
