BIOB34H3 Midterm: [BIOB34] Ch.1-4 Midterm notes
Document Summary
Refer animal physiology as the study of how animals work by knut schmit-nelsen. Physiology: study of normal functioning of a living organism and its component parts. Study structure and function of various parts of animals, and how parts work together. Physiological process: -product of activities of complex tissues, organs and systems. Obey physical and chemical laws (e. g. electrical laws) Usually regulated to maintain internal condition within acceptable ranges (homeostasis) Physiological phenotype is product of genotype and the environment. Homeostasis: -internal constancy maintained through feedback loops that sense condition. Arises as product of genetic makeup, interact with environment. Product of processes at different levels of biological organization/systems. Genotype: genetic makeup, product of evolutionary change in organism over many generations. Adaptation: refer to trait that confers increase in reproductive success in strictest evolutionary sense. Refer to phenotypic changes that improve performance of a physiological system. Phenotypic plasticity: single genotype generates more than one phenotypes.
