Document Summary
Epidemiological studies: a natural experiment that a population conducts on itself, probably without knowing they are doing so: in a large enough population exposure (the experimental factor the researcher is looking at) varies, tries to answer the question do differences in outcome correlate with exposure , cannot prove cause and effect; can only suggest correlations. Types: epidemiological or observational studies: cannot prove cause & effect, correlation only, cannot control but easily generalizable, animal experiments: easy to control, not easily generalized to humans, human experiments: moderately difficult to control, but more generalizable (very expensive) Digestion: begins in the stomach where the hcl acid denatures protein, this change in shape allows the proteases (digestive enzyme that breaks peptide bonds between amino acids) to act on the proteins, si finished the digestion of protein by also producing protease for protein breakdown into amino acids.
