1. Statistical Significance Measure or confidence that the results obtained.
2. Scientific Theory A hypothesis that continues to hold up after many
years of testing.
3. Epidemiology The study of patterns of disease in populations.
4. Anecdotal evidence informal observation that hasn't been systematical-
ly tested; interesting but often unreliable.
5. Randomized Clinical Trial controlled medical experiment (placebo)
6. All living things have five things in 1. Grow
common: 2. Metabolism
3. homeostasis
4.Reproduction
5. sense/response stimuli
7. Matter (building block) Anything that takes up space and has mass.
8. Atoms (building block) smallest unit of and element.
9. Covalent bond When electrons are shared
10. Ionic >1.7
11. Polar covalent 0.5-1.7
12. Nonpolar covalent 0.0-0.4
13. Ionic bond occurs when more electronegative atom steals the
other atom's electron no sharing.
14. Ion charged particle (unequal electrons and protons)

15. non polar molecules do not dissolve in water (ex: methane)
16. Water polar molecule; forms hydrogen bonds with water
and molecules.
17. Solute anything being DISSOLVED
18. Solvent DOES the dissolving
19. Hydrophilic interact with water
20. Hydrophobic does not interact with water
21. Cohesion water molecules cling TOGETHER.
22. Adhesion water molecules cling to SURFACE
23. High absorbance lager liquid range
24. Organic Molecules have carbon-based backbones and at least one C-H
bond.
25. Inorganic Molecules lack carbon-based backbones and C-H bonds.
26. Four types of organic macromolecules 1. Carbohydrates
make up living things: 2. Proteins
3. Lipids
4. Nucleic Acids
27. Carbohydrates A chain of sugar monomers and hydrophilic.
28. Monosaccharides that backbone of carbon atom in monosaccharides.
29. Proteins Made of amino acids; help speed up the rate of
chemicals
