Passage V

Seeds from 100 plants of an annual wildflower species were collected and their mass (weight) was determined (Figure 1).

The seeds were divided into 3 groups. One group was planted in pots in a greenhouse. The second group was planted in meadow sites that had been cleared of vegetation. The third group was planted in meadow sites that had not been cleared of vegetation. The resultant plants were dried after flowering. Plants and seeds were weighed separately. Figure 2 shows the mass of the plants.

Figure 3 shows the average mass of seeds produced by the plants.

25. It was hypothesized that seeds under 0.5 mg did not contain enough stored nutrients to produce plants under any conditions. The data for which of the following sțudy site(s) in Figure 2 disprove this hypothesis?

Answer and Explanation

Your Answer is

Correct Answer is C

Explanation

Looking at Figure 2, if you want to disprove the point of view in the title, you need to look at which set of data can still produce plants when the abscissa (seed mass) is less than 0.5mg. We found that plants are produced except uncleed sites, so Choose C
