Botanist Dr. Elena Torres investigated how desert wildflowers adapt to drought conditions to ensure pollination. Torres claimed that when soil moisture levels are low, these wildflowers produce a stronger scent to attract pollinators from further away. Which choice, if true, most directly supports Torres's claim?
- ADesert wildflowers in low-moisture soil produced larger flowers but fewer seeds than those in high-moisture soil.
- BDesert wildflowers that produce scent are generally more resilient to extreme temperatures than unscented wildflowers.
- Desert wildflowers grown in low-moisture soil released significantly higher concentrations of scent molecules than those grown in wet soil.Answer
- DDesert wildflowers attracted the same number of pollinators regardless of whether they were in dry or wet soil.
Answer
The choice showing that desert wildflowers grown in low-moisture soil released higher concentrations of scent molecules than those grown in wet soil.
The correct answer is the choice stating that wildflowers in low-moisture soil release higher concentrations of scent molecules. This finding provides direct, measurable evidence of the relationship claimed by the researcher: that dry soil conditions lead to stronger scent production.
