Use the terms kinetic energy and chemical potential energy to describe the types of energy demonstrated as you eat an apple on your way to class

When you eat an apple, your body is transforming that apple and storing chemical potential energy from it. Now, when you move, your body has kinetic energy (like every moving object) and this energy can not "just appear", so this energy actually comes from the stored chemical potential energy in your body, that is being transformed into kinetic energy as you move.

what type of charge does it have? negative

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
