Question

Which of the following hypotheses is the best for this scenario?
"In a high school science lab, a group of students is conducting an experiment to determine the amount of water needed to grow a seed into a fully mature plant. The students are investigating the effect of varying water amounts on the growth and development of bean plants."

Bean plants will grow best when receiving a moderate amount of water, and excessive or insufficient water will result in stunted growth or plant mortality.
Bean plants will grow best when receiving a moderate amount of water, and excessive or insufficient water will result in stunted growth or plant mortality.

Bean plants will grow best when they receive the least amount of water, as this will encourage them to develop deeper roots and seek out water.
Bean plants will grow best when they receive the least amount of water, as this will encourage them to develop deeper roots and seek out water.

The amount of water has no effect on the growth and development of bean plants; all plants will grow equally well regardless of the water amount.
The amount of water has no effect on the growth and development of bean plants; all plants will grow equally well regardless of the water amount.

Bean plants will grow best when they receive the most amount of water, as this will provide them with more nutrients and encourage faster growth.

The best hypothesis for the given scenario is:

**"Bean plants will grow best when receiving a moderate amount of water, and excessive or insufficient water will result in stunted growth or plant mortality."**

This hypothesis is grounded in established botanical principles that suggest both overwatering and underwatering can negatively impact plant health, while a moderate amount of water generally promotes optimal growth and development. The other options either propose an extreme position (too little or too much water) or suggest that water has no effect, which contradicts basic understanding of plant biology.
