Susan has just moved into a new house. For some reason, she cannot get the grass to grow in her yard. She decides to grow small amounts of grass inside her house as part of an experiment. The first group of grass is exposed to a light intensity of 400. The second group is exposed to a light intensity of 1200. Using the graph, which of the following should be expected from Susan’s two groups of plants?

Group of answer choices

The plants at a light intensity of 1200 will produce more oxygen than the plants at 400.

The plants at a light intensity of 1200 will perform only stage 1 of photosynthesis.

The plants at a light intensity of 400 will produce more glucose than the plants at 1200.

The plants at a light intensity of 400 will grow more quickly than the plants at 1200.

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.
