Human Biology exam 1 questions with
correct answers rated 100% correct.
biology ANS - is the study of life
what is life? ANS - 1. living things contain nucleic acid, protiens, carbohydrates, and lipds
2. living things are composed of cells
3. Living things grow and reproduce
4. Living things use energy and raw materials
5. Respond to their environment
6. maintains homeostasis
7. adaptive traits
what are humans made of? ANS - 1. molecules
2. Cell
3. Tissue
4. Organ
5. organ systems
6. individual
7. population
Where do humans fit in the overal scheme of life? ANS - Eukarys
Animals
Invertabrates and vertabraes
Community ANS - All the species in an ecosystem that can interact
Ecosystem ANS - A community and its physical environment
,Biosphere ANS - The part of the eart that supports life
Critical thinking involves ANS - inductive reasoning
deductive reasoning
inductive reasoning ANS - individual facts lead to a general conclusion
deductive reasoning ANS - a general statement leads logically to a specific conclusion, "if, then"
Human Science involves ANS - clinical trials
epidemiological studies
Clinical trials ANS - Use human volunteers after successful, safe initial animal studies
- 3 phases: with increasing numbers before FDA approval
- gold standard
Epidemiological ANS - Observe patterns that occur in large populations
Gold Standards ANS - double blind placebo-controlled studies
How to tell the difference between psuedoscience and science ANS - Is the information consistent with
information from other credible sources?
How reliable is the source of the information?
Were proper scientific procedures employed?
Were experimental results properly interpreted? (+ check the methods!)
Are there any other possible explanations for the results?
Chemistry ANS - is the basis
, of matter
and life (Biology!)
Matter ANS - takes up space and has mass
Atoms ANS - units of matter
cannot be broken into smaller substances by ordinary chemical means
made of protons, neutrons, electrons
Element ANS - pure form of matter with only one kind of atom
Isotopes ANS - atoms with the same number of protons (and electrons) but different number of
neutrons
Radioisotopes ANS - are unstable and emit particles or energy
Ion ANS - an atom that has gained or lost electrons; has a + or - charge
Molecule ANS - two or more atoms that join together by chemical bonds
Compound ANS - a molecule made of two or more elements
Organic Molecules ANS - contain carbon-carbon bonds
Inorganic Molecules ANS - No carbon-carbon bonds
electron shells ANS - of an atom are involved in bonding
Are complete with 2 electrons in the first "shell" and 8 electrons in successive "shells"
