1 1 Characteristics i of life Order: Ants building a colony Evolutionary adaption: Dogs becoming domesticated i Response to the environment: Bacteria becoming resistance Regulation: Homeostasis Energy processing: Me eating a glizzy i Reproduction: Me making babies Growth and development: Cubs growing up + selection traits: Continuing due to organism bene ting from said traits -selection traits: gradually becoming recessive due to not helping organism Descant with modi cation: Focuses on what traits are pass down Natural selection: Focuses on what traits bene t a organism Characteristics share by all cells Enclosed by a membrane Use DNA Two mains forms of cell Eukaryotic Prokaryotic Cycling of nutrients, in which materials acquired by plants eventually return to the soil-this is the role of decomposers The ow of energy from sunlight to producers to consumers Two causes of evolution: Mutation: A change in the usual DNA sequence Happens due to errors with DNA replication Happens due to the damaging e ects of chemicals and radiation Change in gene expression: On and o Happens due to environmental factors Both At the highest level, life is classi ed into three domains: Bacteria one cell E coil Salmonella Archaea: single cell Thrive in extreme conditions Thermophiles Both made up of single cell organism Do not have a nucleus No membrane bound organelles Eukaryote Uni cellular-Multi Animals Plants The limitations of science are set by its naturalism Science seeks natural causes for natural phenomena Science cannot support or falsify supernatural explanations, which are outside the bounds of science Taxonomy is the branch of biology that names and classi es species into a hierarchical order Kingdoms and domains are the broadest units of classi cation
