Question 2(multiple choice worth 4 points) (02.02 mc) the graph shows the population of alligators and insects in a pond ecosystem where cricket frogs live. a graph with the title species population is shown. the y axis title is population and next to it is an arrow pointing upwards. the x axis title is year and the values 1, 2, 3 4. 5 are marked on the x axis. a solid slanting graph line is shown sloping gently upwards. a straight broken graph line is shown. a key is shown at the bottom right of the graph. next to the straight line is written alligators and next to the broken line is written insects. how will this impact the population of cricket frogs over time? decreases because the number of predators increases increases because the number of predators increases decreases because the number of prey decreases increases because the number of prey decreases

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.

Three cards with holes are arranged in a straight line. a light is shined through the first card’s hole and travels through all three cards. what does this tell you about light rays? a) that light is reflected b) that light is refractive c) that light travels in a straight line d) that light does not travel in a straight line

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?
