What are atoms and how are the subatomic particles diagrammed?

Atoms are the basic building blocks of all matter (solids, liquids, gases and plasma) in the universe. For example, you and I are made entirely of atoms. The device you're using to view this answer is made of atoms.

Within atoms are subatomic particles. These include protons, neutrons and electrons. Protons and neutrons are located within the nucleus of an atom while electrons orbit around the nucleus, arranged in shells (the "outside part" of an atom). Changing the number of subatomic particles there are in an atom can change its properties (ex. what element it represents, how reactive the substance is, etc.)

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
