Presentation Transcript

  1. Block 3 Questions to Consider • Definition/Illustration • Shows some activity of “life” • Barrier to solvent (spectrum of solubilty) • Influencing (IV) factors (quantified) • Heat Proportion, concentration(water amt) • pH • Shake, stir, swirl (also time of same) • Things to measure/observe (DV) • number/frequency • Absolute size (ref measure/clear plastic ruler) • Concentration/density of “cells” • Trace movement/uptake of substances • shape • Chemical explanation • Protein in solution – unstable chemically • Dehydration of components/role of water • Colloidal properties/why? • Connection to origin of life question • Primative cells may have been like this • Chemical evolution

  2. Notes from Prelab Characteristics of Life/Cell Theory recollections metabolism (catabolism,anabolism) – energy ability to reproduce organism/ cells (growth and repair) Self movement/reaction to stimulus Theories as to origin of life RNA world – chemical evolution panspermia
