The distance from Earth to Moon can be accurately calculated by pointing high-powered lasers into the Moon’s surface. The time it takes did the light to return is used to find the distance. To make this possible, astronauts on the Apollo 11 Moon mission had to place a device on the Moon that would— A. Store the laser light for future use. B. Bounce the laser light back to Earth. C. Allow the laser light the pass through. D. Change the frequency of the laser light.

Ali hypothesized that increasing fertilizer would increase plant growth. four groups of thirty similar plants were given 0 to 15 ml of fertilizer, as shown in the graph. the change in plant height for each group over a two-week period was averaged and recorded. plant group fertilizer added (ml) avg. growth (cm) a 0 4 b 5 6 c 10 8 d 15 3 what is the best conclusion based on this data? the hypothesis was not supported because the data indicated that fertilizing plants does not improve plant growth. the hypothesis was supported; to get the best growth, use 5 milliliters of fertilizer per plant. the hypothesis was not supported; the data indicated that too much fertilizer can inhibit plant growth. the hypothesis was supported; to get the best growth, use 15 milliliters of fertilizer per plant.
