Explain why scientists use shared characteristics to make cladograms.

For ai it's atomic number is 13 and it's mass number is 27 how many neutrons does it have

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
