Why is Newton's Law of Gravity considered a law and not a theory?

• Newton combined data from other scientific hypotheses to form his law.

• Newton had to create a law because others could dispute his gravity explanation.

• Newton created an explanation to answer why falling objects fall.

• Newton could predict a falling object's behavior, but not the reason why it fell.

A fair explanation about the data in the diagram might be —

• atmospheric moisture increases at night

• warm air holds less water than cool air

• as air cools, the relative humidity increases

• more data must be gathered before an explanation is possible

Which experimental design would best determine the effect of low temperatures on the growth of bean plants?

• Measure the rate of growth in 20 bean plants of the same species, each grown at a different low temperature.

• Measure the rate of growth in 20 bean plants of the different species, each grown at the same low temperature.

• Measure the rate of growth in 20 bean plants of the different species, each grown at a different low temperature.

• Measure the rate of growth in 20 bean plants of the same species, each grown at the same low temperature.

A student is testing the specific gravity of a rock sample that she found. She knows that the sample is either galena, gold, pyrite, or silver, and has hypothesized that the sample is galena. Using the shown observations and chart, is the student's hypothesis correct?

• The hypothesis is correct because the sample is galena.

• The hypothesis is incorrect because the sample is pyrite.

• The hypothesis is incorrect because the sample is gold.

• The hypothesis is incorrect because the sample is silver.

For the hypothesis "If there is less sunlight then there will be fewer producers", what is the dependent variable?
