Alkanes with more carbon atoms have higher boiling and melting points, so some of them are solids at room temperature. Kathy did some experiments on two different alkanes and one of the alkanes had twice as many carbon atoms than the other. She would notice that which alkane would require a higher temperature to melt alkane with fewer carbon atoms or alkane with more carbon atoms??
alkane with more carbon atoms?

Objects with greater mass have a stronger force of gravity. If Milo adds mass to an object, what will happen to the force of gravity that object generates decreases or increases?
increases

The folds present in the membrane increase the surface area allowing more ribosomes to be present on the ER, thereby allowing greater protein production. If Mona is creating a membrane to filter out some dirty water and she creates more folds in the membrane, what happens to the total surface area of that membrane increases or decreases?
increases

Bigger stars produce more energy, so their surfaces are hotter. Jan is comparing stars, specifically a small star and the larger Sun. Given the size of each, Jan can tell that the Sun puts out heat that is lesser or greater?
lesser
