| A | B |
|---|
| atom | smallest/basic unit of life. |
| element | Substance composed of identical atoms like Carbon, Oxygen... |
| molecule | 2 or more of the same atoms/elements bonded together. |
| compound | 2 or more of the different elements bonded together. |
| cohesion | Property of water that water is attracted to other molecules of water. |
| surface tension | Property of cohesion |
| adhesion | Water is attracted to other materials. |
| capillary action | Property of adhesion and shows how water can move up other materials. |
| mixture | 2 or more substances mixed together but not chemically combined (can be seperated) |
| solution | well mixed, mixture like salt-water |
| Ph scale | A scale that measures whether something is an acid, base, or neutral. |
| acid | A lot of H+ ions |
| base | A lot of OH- ions |
| covalent bond | Two things bond togehter and share electrons |
| ionic bonds | When things bond together and take electons |
| non-polar molecules | Molecules that do not have a charge. |
| polar molecules | Molecules that have a charge. |
| organic | living things- always will contain carbon. |
| monomer | Simplest form of the organic compound. |
| polymers | Monomers linked together to make bigger chains of the organic compound |
| organic compound | Carbohydrates, lipids, proteins, and nucleic acids. Always contain a combination of C,N,H, and O. |
| carboyhdrates | The monomer is a monosaccharide. |
| monosaccharide | The monomer for a carbohydrate. |
| disaccharide | Two monosaccharides put together. (Glucose+ fructose=sucrose) |
| isomeres | glucose, fructose and galactose are all examples because they are made of the same elements (C6H12O6) |
| dehydration synthesis | When monomers are added together, they go through this and lose a water molecule. |
| hydrolysis | When a polymer is broken apart, it goes through this and a water molecule is added. |
| lipids | fatty acids are the monomers and can be recognized by longn chains of hydrogen bonds. |
| hydrophilic | water loving |
| hydrophobic | water hating |
| triglyceride | A lipid made of one glycerol and 3 fatty acids. |
| saturated fat | Bad fat that is solid and comes from animals/animal products |
| unsaturated fat | liquid and comes from plants. The better fat. |
| cholesterol | A type of lipid that is found in our cell membranes and hormones. |
| polysaccharide | long chains of monosaccharides. The most complex carbohydrates. |
