BIO 101 Lecture Notes - Lecture 1: Irradiation, Natural Selection, Eukaryote
Document Summary
Organized living and nonliving world at many levels. Levels: atom, molecule, organelles, cell, tissue, organ, organ system, organism, species, population, community, ecosystem, biosphere. All scientific inquiry is based on a small set of assumptions or principles such as natural causality, uniformity in space and time, similar perception. Creationism is contrary to the principle of uniformity in time and natural causality. Scientific theory is a general explanation for important natural phenomena. Processes that underlie evolution: genetic variation among members of a population. 2: natural selection of individuals whose survival and enhanced reproduction are due to the. Inheritance of those variations by offspring of parents carrying the variation favorable variations they carry. 1: copying mistakes in dna during cellular reproduction. All cells contain: genes that provide information to direct the cell, organelles, small specialized structures that perform specific functions, plasma membrane that encloses the fluid cytoplasm and organelles from outside world.
