If the research shows that the reduction in the number of small fish is to blame for the malnourishment of the sea lions, they are likely to see an increase in the amount of deaths and a decrease in the amount of births. Explain how the reduction in the amount of fish has an impact on the population of a different species, like the sea lion. If we assume that Orcas feed on sea lions, how would the decrease in the number of small fish affect the Orcas?

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?
