The document summarizes key concepts in biology and chemistry. It defines three domains that species are grouped in: Archaea, Bacteria, and Eukarya. It also outlines the correct order of the scientific method as observe, ask questions, make hypotheses, make predictions, and conduct tests. Finally, it provides a definition of biology as the study of organisms, their characteristics, functions, and interactions.

*~Brain Stretch~* 1. What are the three domains that species are grouped in? Archea, Bacteria, and Eukarya 2. What is the correct order of the scientific method? (Tests, Hypotheses, Observe, Predictions, and Questions) Observe, Questions, Hypotheses, Predictions, Tests 3. What is biology? The scientific study of organisms, including their characteristics, functions, and interactions.
Terms to Know Atom = The smallest unit of a chemical element; made up of electrons, protons, and neutrons (except in a hydrogen atom). Molecule = A chemical substance made up of two or more atoms joined by covalent bonds or ionic attractions. Covalent Bond = A chemical bond based on the sharing of electrons between two atoms. Water = H2O; H+ (hydrogen ion) helps make solutions more acidic while OH- (hydroxyl group) helps make solutions more basic. Monomer = [“Mono” means one, “mer(os)” means unit] A small molecule. Capable of making oligomers or polymers. Oligomer = [“Oligo” means few, “mer(os)” means unit] A polymer made up of few monomers. Polymer = [“Poly” means many, “mer(os)” means unit] A large molecule.
Hydrolysis Hydro = Water Lysis = Separation A chemical decomposition in which a compound (polymer) is split into other compounds (monomers) by reacting with water. One monomer receives a hydrogen ion (H+) and the other receives a hydroxyl group (OH-). Releases energy
Condensation Con = Together Dense = Compact Ation = Act or Process A type of reaction in which two organic molecules (monomers) covalently bond to form a larger molecule (polymer) as well as a simple molecule (water). Requires energy A.K.A. Dehydration Reaction
