Document Summary
Stoichiometry: mass and energy can not be created nor destroyed (mass must be conserved) Hypothesis: an explanation for a puzzling observation it answers the causal question. There are an unlimited number of hypothesis for each causal question some hypotheses off-hand appears to have more merit than others scientific inquiry seeks to verify or refute hypotheses. Reproduction purposes (i. e. mating calls), territorial displays, communication to other birds (i. e. could be predators, etc. Complementary hypotheses: cell/molecular, physiology, evolution, and ecology behaviour biological hypotheses usually fall within one of these classes proximate hypotheses are cell/molecular and physiology ultimate hypotheses are ecology/behaviour and evolution. Food availability, temperature (live longer when cold) Causal questions (why is it like that), 3. We need to decide which hypothesis is probably correct. Hypothesis testing: involves the collection of information imagination and creativity helpful sometimes appear to only obliquely relate to hypotheses different ways to do this: experiments, observational studies, meta-analysis, mathematical modeling.
