BIOL 1116 Lecture Notes - Lecture 10: Natural Selection, Urethra, Hemispherical Combustion Chamber
Document Summary
The study of structure and the relationships among structures physiology. Themes in the study of how body structures function. Biology life is organized at many hierarchical levels close correlation between structure. Tissue integrated group of similar cells that preform a common function. Organ system consists of multiple organs work together to preform organism a vital body function. A birds flight apparatus an feathers give wings shape. Weight muscles attatched keep weight at off breast plate. 3 base of wings wings be provide power bones evolved same structure as human arm birds fewer bones. 3 hollow animal form reflects natural selection phenotype observable. Natural selection involves editing rather than creating does not imply a process of conscious intervention or a response to a need can lead.
