Question

1. look at the chart. then, choose the best answer.

seed germination (sprouting)
field | soil temperature | number of seeds germinated out of 100 (sprouted three weeks)
control field 1 | soil kept at 7 °c | 3
control field 2 | soil kept at 7 °c | 7
control field 3 | soil kept at 7 °c | 6
experimental field 4 | soil kept at 24 °c | 78
experimental field 5 | soil kept at 24 °c | 65
experimental field 6 | soil kept at 24 °c | 88
what is the best conclusion or reasoning of the data from the seed germination experiment?
○ most seeds are unable to sprout.
○ seeds are more likely to sprout in cooler soil.
○ seeds are more likely to sprout in warmer soil.
○ temperature does not affect germination rates.

Explanation:

1. Analyze the data for cooler soil (7°C): The number of seeds germinated in control fields (7°C) are 3, 7, and 6. The average or typical number is low (e.g., total is 3 + 7 + 6 = 16, average ~5.33 out of 100).
2. Analyze the data for warmer soil (24°C): The number of seeds germinated in experimental fields (24°C) are 78, 65, and 88. The total is 78 + 65 + 88 = 231, average ~77 out of 100.
3. Compare the two groups: Warmer soil (24°C) has much higher germination rates than cooler soil (7°C).
4. Evaluate the options:

• "Most seeds are unable to sprout" is incorrect because in warmer soil, most seeds (around 77 on average) do sprout.
• "Seeds are more likely to sprout in cooler soil" is incorrect as cooler soil has low germination.
• "Seeds are more likely to sprout in warmer soil" matches the data (higher germination in 24°C soil).
• "Temperature does not affect germination rates" is incorrect as temperature clearly affects (huge difference between 7°C and 24°C groups).

Answer:

Seeds are more likely to sprout in warmer soil.
