The model can be used to explain the physical properties of solids, liquids and gases. Carbohydrates are commonly used by cells as respiratory substrates. The particle model represents particles by small, solid spheres. Note: Some solids, liquids, and gases are made of atoms, and some are made of molecules. This can also be explained by the fact that water molecules are very attracted to each other. When an electrical impulse reaches the end of an axon entering the synapse, the axon releases a transmitter substance. Spittlebugs, a common insect, spread the disease: when they bite an infected leaf, the bacteria move into their saliva, and the bugs transmit the disease when they feed on their next healthy plant.

It describes the arrangement, movement and energy of particles in a. Despite their great variety, the cells of all living organisms contain only a few groups of carbon-based compounds that interact in similar ways. If a gas is allowed to cool, particles slow down and bonds reform to make a liquid (condensing) and if the liquid cools enough it turns to a solid (freezing). Atoms are extremely small and are made up of a few even smaller particles. The particle model represents particles by small, solid spheres.
