ACT Science (data and features)

In general, the results of Study 1 suggest that peony seeds that are placed in a petri dish containing damp paper are most likely to germinate when they are maintained at which of the following temperatures?

• 13° C

• 18° C

• 23°C

• 28°C

Suppose another set of 25 peony seeds had been included in Study 2 and these seeds had a storage temperature of 25°C and a germination temperature of 18°C. Based on the information provided, the number of seeds that would have germinated after being maintained for 30 days would most likely have been closest to:

• 0

• 8

• 16

• 24

In Study 2, at the storage temperature of 5°C, as germination temperature increased from 13°C to 28°C, the number of seeds that germinated:

• decreased only.

• increased only.

• decreased, then increased.

• increased, then decreased.

Which of the following sets of seeds were exposed to the same conditions prior to being placed in the petri dishes?

• The seeds from Study 1 that were stored for 8 weeks and the seeds from Study 2 that were stored at 5°C

• The seeds from Study 1 that were stored for 8 weeks and the seeds from Study 2 that were stored at 15°C

• The seeds from Study 1 that were stored for 10 weeks and the seeds from Study 2 that were stored at 5°C

• The seeds from Study 1 that were stored for 10 weeks and the seeds from Study 2 that were stored at 15°C

A student stored 100 peony seeds at a constant temperature for 10 weeks. The student then divided the seeds into 4 sets and maintained them as described in Study 2. The results were as follows (See image)

These seeds most likely had a storage temperature of:

• 0°C

• 5°C

• 10°C

• 15°C
