Answer:
D. A molecule of glucose
Explanation:
Potential energy is defined as the energy that is stored, or conserved, in an object or substance. The act of contracting muscles, emitting light flashes, flying or water moving are all dissipating energy and, thus, do not represent an example of kinetic energy. On the other hand, a molecule of glucose stores energy and therefore is an example of potential energy.
I believe that would be natural selection
Matter can exist in one of three main states: solid, liquid, or gas.
Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.
Liquid matter is made of more loosely packed particles. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained.
Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed
liquid: A substance that flows and keeps no definite shape because its molecules are loosely packed and constantly moving. It takes the shape of its container but maintains constant volume.
gas: A substance that can only be contained if it is fully surrounded by a container (or held together by gravitational pull); a substance whose molecules have negligible intermolecular interactions and can move freely.
solid: A substance that retains its size and shape without a container; a substance whose molecules cannot move freely except to vibrate.
