In an area deficient in nitrogen, why would a plant, such as a legume, have an advantage over another type of plant? A- It reproduces at a much faster rate when exposed to limited amounts of nitrogen in the air

B-It is an economically profitable crop.

C-It can survive for longer periods of time in arid areas due to its extensive root structure.

D-It is able to pull in and use nitrogen from the atmosphere through the process of nitrogen fixation

Sally and sue were investigating the topic of friction in science. they used a small car and a ramp as seen in the picture to test what they were learning. they knew that they slipped easily on waxed floors but not on carpet, so they decided to change the material on the surface of the ramp to see what happened. they planned to use glass, carpet, aluminum foil, and sandpaper and run the car down the ramp over each surface. what would be the best research question to guide the girls' experiment? a) does the amount of surface area affect the friction on the moving car? b) will the car travel fastest on the glass surface? c) how does the angle of the ramp affect the speed of the car? d)do rougher surfaces tend to create more friction than smooth surfaces?
