After collecting samples of the material found growing on last month's leftovers at the back of your fridge, you realize that you have discovered a new type of organism. you find that the cells have distinct subunits within. further, several of these subunits, which you have nicknamed groucho, chico, and harpo, seem to be involved in the production and transfer of certain molecules. molecule dumont, as you call it, appears after a messenger molecule is sent from groucho to chico. dumont then travels to harpo, where it is covered in membrane and (eventually) released from the cell.
dumont is most likely what type of molecule?

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?
