Community - ANSWER-All the species in an ecosystem that can interact
Ecosystem - ANSWER-A community and its physical environment
Biosphere - ANSWER-The part of the eart that supports life
Critical thinking involves - ANSWER-inductive reasoning
deductive reasoning
inductive reasoning - ANSWER-individual facts lead to a general conclusion
deductive reasoning - ANSWER-a general statement leads logically to a specific
conclusion, "if, then"
Human Science involves - ANSWER-clinical trials
epidemiological studies
Clinical trials - ANSWER-Use human volunteers after successful, safe initial animal
studies

Epidemiological - ANSWER-Observe patterns that occur in large populations
Gold Standards - ANSWER-double blind placebo-controlled studies
How to tell the difference between psuedoscience and science - ANSWER-Is the
information consistent with information from other credible sources?

Chemistry - ANSWER-is the basis
of matter
and life (Biology!)
Matter - ANSWER-takes up space and has mass
Atoms - ANSWER-units of matter
cannot be broken into smaller substances by ordinary chemical means
made of protons, neutrons, electrons
Element - ANSWER-pure form of matter with only one kind of atom
Isotopes - ANSWER-atoms with the same number of protons (and electrons) but
different number of neutrons
Radioisotopes - ANSWER-are unstable and emit particles or energy
Ion - ANSWER-an atom that has gained or lost electrons; has a + or - charge
Molecule - ANSWER-two or more atoms that join together by chemical bonds
Compound - ANSWER-a molecule made of two or more elements
Organic Molecules - ANSWER-contain carbon-carbon bonds
Inorganic Molecules - ANSWER-No carbon-carbon bonds
electron shells - ANSWER-of an atom are involved in bonding
Are complete with 2 electrons in the first "shell" and 8 electrons in successive
"shells"
Covalent Bonds - ANSWER-shares electrons
Equally= nonpolar
Unequally= polar
