Document Summary
Physiology critical component of phenotype of organisms variation can influence performance and reproductive success evolves over time and contributes to animal biodiversity. Phenotype result from interactions b/w genes + environment throughout a lifetime. Physiologists study how organism work across multiple levels of biological organization. Implications of physiology on populations often explored to understand ecology and conservation. Porcelain crabs are impacted by climate change b/c warming temp. impacts their heart function. #2 physiology obeys the laws of chemistry and physics. ), mechanical theory (i. e. flow, pressure, resistance, etc. ) important in physiological processes/understanding. Electrical potentials across membranes powers many physiological processes. Larger an animal, the larger the volume - this volume with be disproportionate to the area of the bones, thus larger bones are needed for larger animals to support the larger mass. Animals can be classified into 2 categories based on their response to changing external environment conditions: Animals can be regulators for some physiological parameters but conformers for others.
