Grinnell College‚ Grinnell‚ Iowa 50112‚ United States S Supporting Information * ABSTRACT: A simple organic chemistry experiment is described that investigates the kinetics of the reaction between 1-bromobutane (BuBr) and iodide (I−) as followed by observing the disappearance of BuBr and the appearance of 1-iodobutane (BuI) using 1H NMR spectroscopy. In small groups of three to four‚ students acquire data to examine the concentrationdependence of both the organic substrate and the nucleophile under

Lab Report 1: Subculturing Adherent Cells Fibronectin‚ integrin alpha 3‚ and actin are all involved in cellular adhesion at both the cellular and molecular levels. Integrins are the primary trans-membrane receptors that mediate dynamic interactions between the extracellular matrix and the actin cytoskeleton whenever a cell is motile. Integrins bind to the extracellular matrix and link to the actin cytoskeleton via a shirt cytoplasmic tail; they also help determine cellular binding specificity because

Kathryn Marchessault Physics Lab LR Tuesday 8-9:55 Due 02/26/15 Experiment #1 Free Fall Experiment Abstract In this experiment we studied the motion of an object in free fall‚ that is an object being dropped from a certain height to Earth’s surface. In this experiment we tested the idea that no matter what the size‚ shape‚ color‚ etc. of the object if it would still experience the same constant acceleration throughout its fall (short distance). The constant downward acceleration it experiences
