Exploring the Connection Between Solubility, Life’s Origin, and Cell Theory

This exploration focuses on the solubility spectrum of substances, including the emulsification of insoluble compounds when shaken. Key factors influencing solubility such as heat, charge type, concentration, and mixing techniques are examined. Observational measures include frequency, density, and size in microscope views. The discussion advances into the role of water in life's genesis, linking present-day cells with their origins. Theories like panspermia and chemical evolution provide insights into life's beginnings, emphasizing essential processes like metabolism and reproduction.

Presentation Transcript

  1. BLOCK 2 Questions to consider • Definition/Illustration • Spectrum of solubilty, insoluble but if shaken, emulsifies=droplets in solvent • Influencing (IV) factors • Heat • Type charge on chemical • Concentration of chemical/amount of water • Acidity/alkalinty (in baseline/guided expt) • Mixing/shaking/swirling etc. • Things to measure/observe (DV) • Number/frequency • density • Size in microscope FOV • Chemical explanation • Interaction between +/- charges (diagram) complex • Reduction of hydration around colloidal particles (research the terms) simple • ? About role of water • Connection to origin of life question • Shows a model for possible genesis • Share feature with present and original “cells”

  2. Notes from Prelab Characteristics of Life/Cell Theory recollections • Cells come from cells • Cells are the smallest unit of life • Metabolizing (respiring, growth, energy transfer via enzymes) • Reproducing • Self-movement as a response to a stimulus ____________________________ Theories as to origin of life • Panspermia- came from across the universe (evidence: amino acids, fossils) • Chemical evolution- primordial soup (requiring: energy transfer, polymerization, reproduction, information molecule)
