Skeletal muscle tissue is found near the bones of the skeleton. These muscles are controlled by the nervous system and allow movement to occur. Smooth muscle tissue is predominantly found in the inner lining of many organs, such as the stomach and intestinal tract. Smooth muscle tissue allows organs to contract on their own. Cardiac muscle tissue is found in the heart. Cardiac muscle also contracts on its own, and it helps the heart beat properly.

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?
