Document Summary
Scientific fact: attempt to state best current understanding based on (cid:1) (cid:1) (cid:1) observations and experiments (cid:1) Carry out experiments, make further observations to test hypothesis. Law: theory that has been tested/confirmed so many times that there. Interpret results to see if they support hypothesis: all he saw were the remaining cell walls of dead plant cells. Glass microscope: better quality/magnification (cid:1) (cid:1) (cid:1) is no doubt of validity (cid:1) (cid:1) Observed: protists from pond water, bacteria from mouth, blood cells, sperm, banded pattern in muscle cells. Recognized structural similarities b/w plants & animals. Cell is basic unit of structure for all organisms. Surface of cell (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Use same genetic program (central dogma: dna rna protein o, genes stored in dna molecules, written in same chemical code, constructed out of same chemical building blocks, interpreted by same machinery, duplicated same way.
