(c) Based on the data in Figure 1, describe whether or how the size of the leopard population appears to have been affected by the lion population over the period for which data were analyzed. The scientists also estimated the consumed biomass of the prey animals of the leopards and lions. They estimated that the lions annually ate a total of approximately 175,000 kg of prey animals. This included approximately 110,000 kg of very large animals. Calculate, to the nearest whole number, the percent of the total biomass eaten by the lions that is composed of very large animals.

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?
