    The purpose of this lab was to hypothesize about membrane traffic in lab‚ explain the differences between the solutions hypertonic‚ hypotonic‚ and isotonic and how they respond using the understanding of the cell membrane structure‚ types of transport mechanisms such as active‚ passive‚ diffusionosmosis‚ and explain the movement of particles moving across the cell membrane. In this lab was divided into two parts. The first part was varying the concentration and the second part was varying the temperature

    1) Make a graph of resting heart rates from Activity 1. Provide a physiological explanation for fluctuations in resting heart rate over time. Discuss a couple of extrinsic factors that influence the autonomic nervous regulation of resting heart rate. The resting heart rate fluctuates over time because it is under control of the autonomic nervous system and the fluctuations are a result of the sympathetic and parasympathetic systems trying to balance each other out. There are many reasons

    Lab Report DIFFUSION AND THE EFFECT OF AMYLASE. Aim: We will interpret and explain the activity of an enzyme added to a solution. We will analyze reactions in different pH ranges. The starch solution will appear blue when mixed with iodine. But after mixing the enzyme amylase to the starch‚ the starches are broken down into simple sugars. Now‚ when the iodine is added‚ no color change exist. Instruments and materials used: 1.) Dialysis bags x2 2.)

    DATE: 21.08.2013 TITLE: Transport across membrane OBJECTIVES: To investigate the effect of concentration of blackcurrant squash on osmosis in chipped potatoes. INTRODUCTION: In biology‚ osmosis is defined as the diffusion of solvent molecules (usually water molecules) across a semi-permeable membrane from a region of lower solute concentration to a region of higher solute concentration. Osmosis is of great importance in biological processes

    Experiment 2 The Cell Membrane Abstract The boundary between any cell and its environment is the plasma membrane‚ composed of a matrix of phospholipid molecules along with a number of different kinds of proteins. Membranes have different properties and a variety of functions‚ in large part determined by the specific proteins within the membrane. This experiment is designed to determine the stress that various factors‚ such as osmotic balance‚ detergents and pH‚ have on biological membranes. There are three

    Introduction In this experiment‚ I measured the impact of two different topical chemicals on growing bacteria over the course of a week. Bleach‚ water‚ hand sanitizer and hand soap were all variables used to observe the effects of the bacteria swabbed from my palm and fingers. Bleach has been the go to product for killing germs and it is because of the similar effects it has with high temperature on the proteins in bacteria. I hypothesized that bleach would be the most efficient way for killing the
