Sam is studying the effects of temperature change on a specific enzyme, catalase. This enzyme is found in cells and helps break down hydrogen peroxide. As part of her project, she measures the rate at which hydrogen peroxide is broken down by catalase at 20, 25, 30, and 35oC Which question BEST describes Sam's science research project?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
