Document Summary

Learning objectives: know and be able to define physiology and its types, define homeostasis, phenotype vs genotype, know the basis for evolution and natural selection.

Based on: biological level of organization, how physiological variation comes about, ultimate goals of the research, physiology questions include aspects from all subdisciplines. Biological level of organization: cell and molecular physiology. Looking at the whole animal: ecological or environmental physiology. Rna proteins macromolecules organelles cells tissues systems organis m, etc: physiologists often study processes at multiple organizational levels. Reductionism understand a system by studying the function of its parts. Emergence the whole is more than the sym of its part. Emergent properties may not be visible by looking only at parts.
