Question

a group of researchers measured a 20 square meter section of a prairie ecosystem and recorded their observations. using the table below, which of the following is a testable hypothesis? quantitative: 20 bees, 47 butterflies, 200 pink flowers, 100 red flowers, 100 blue flowers, 7 trees qualitative: the sun was shining brightly, insects flew by quickly, 4 butterflies flew together to another area of the prairie, bees tended to pollinate at blue flowers a. the butterflies did not like this section of the prairie. b. if there are more blue flowers, then more bees will pollinate in this area. c. if the sun is not so bright, then insects will like this area better. d. the trees in the prairie represent a population.

Explanation:

A testable hypothesis is one that can be proven or disproven through experimentation or observation. Option B presents a relationship between the number of blue - flowers and bee pollination that can be tested by observing and counting in the prairie. Option A is a statement about butterfly preferences which is hard to objectively test. Option C is about insects' preference based on sunlight which is difficult to precisely measure and test. Option D is a statement about trees representing a population which is not a testable hypothesis in the context of the data given.

Answer:

B. If there are more blue flowers, then more bees will pollinate in this area.
