Kaylee wants to test her hypothesis that she performs better on tests after getting more sleep. in which way will she best be able to do this? by analyzing her test scores when she gets the same amount of sleep by asking her friends if sleep affects their test scores by analyzing her average test scores after nights with different amounts of sleep by reading online about the relationship between sleep and test scores

The correct answer is: by analyzing her average test scores after nights with different amounts of sleep.

This is the best way to approve her hypothesis, because she can compare the results of the tests influenced by different amounts of sleep.

The independent variable (the one that is changed by the scientist) in this hypothesis would be hours of sleep. The dependent variable (the one that is observed and that responds to the change made by the independent variable) would be result of test.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
