Module 5 Vocab Exploring Creation with Biology
| Question | Answer |
|---|---|
| Matter | Anything that has mass and takes up space |
| Model | Explanation or representation of something that cannot be seen |
| Element | Collection of atoms that all have the same number of protons |
| Molecules | Chemicals that result from atoms linking together |
| Physical change | Change that affects the appearance but not the chemical makeup of a substance |
| Chemical change | Change that alters the makeup of the elements or molecules of a substance |
| Phase | One of three forms, solid, liquid, or gas, which every substance is capable of attaining |
| Diffusion | Random motion of molecules from an area of high concentration to an area of low concentration |
| Concentration | Measurement of how much solute exists within a certain volume of solvent |
| Semipermeable membrane | Membrane that allows some molecules to pass through but does not allow other molecules to pass through |
| Osmosis | Tendency of a solvent to travel across a semipermeable membrane into areas of higher solute concentration |
| Catalyst | Substance that alters the speed of a chemical reaction but is not used up in the process |
| Organic molecule | Molecule that contains only carbon and any of the following: hydrogen, oxygen, nitrogen, sulfur, phosphorous |
| Biosynthesis | Process by which living organisms produce larger molecules from smaller ones |
| Isomers | Two different molecules that have the same chemical formula |
| Monosaccharides | Simple carbohydrates that contain 3 to 10 carbon atoms |
| Disaccharides | Carbohydrates that are made up of two monosaccharides |
| Polysaccharides | Carbohydrates that are made up of more than two monosaccharides |
| Dehydration reaction | Chemical reaction in which molecules combine by removing water |
| Hydrolysis | Breaking down complex molecules by the chemical addition of water |
| Hydrophobic | Lacking any affinity to water |
| Saturated fat | Lipid made from fatty acids that have no double bonds between carbon atoms |
| Unsaturated fat | Lipid made from fatty acids that have at least one double bond between carbon atoms |
| Peptide bond | Bond that links amino acids together in a protein |
| Hydrogen bond | Strong attraction between hydrogen atoms and certain other atoms (usually oxygen or nitrogen) in specific molecules |
