ACTIVITY ONE- Cell Transport Mechanisms and Permeability: Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. Molecular weight affects the rate of diffusion because the bigger the size of the molecule the longer it will take to diffuse. Membrane size is another variable that affects the rate of diffusion because if the membrane’s pores are small it will take molecules longer to diffuse though it than if the pores were larger. Also‚ membrane thickness

Investigate factors affecting cell membrane permeability in beetroot. Research Question: How does variation in temperature affect the permeability of cell membranes? Background Information: In this investigation I will want to identify how variations in temperature effect the permeability through the use of a beetroot. I predict that as the temperature of the water increases so will the dispersion of the pigment. Independent Variable: The temperature of water will be increased in increments of 10oC

“Maybe tomorrow‚ we’ll all wear 42‚ so nobody could tell us apart.” General manager of the Brooklyn Dodgers‚ Branch Rickey‚ decided to draft Jackie Robinson into the baseball team. Rickey knew the negative feedback he would receive and he refused to let society make the decision for him. Therefore‚ he went seeking for a baseball player who could meet his standards‚ physically and mentally. While some differences between Brian Helgelands movie 42 and the segregation in society and the Jim Crow laws

Erica Osorio 5057497 Christian Roque and Rogerlio The Mechanisms by which E.Coli Cells Developed Immunities toward Ampicillin due to Plasmid and DNA Consumption U34 Abstract During the ampicillin experiment the ability to transform cells to make them adaptable to their environment was studied. The E.coli bacterial cell was used in order to observe how its DNA was able to change and develop immunity towards ampicillin. In order for this change to occur the use of several

Active and passive transport are the ways in which cells allow things to move into and out of the cell through the cell membrane. They include many different ways to transport things. Passive transport requires no expenditure of energy by the cell. However‚ Active transport requires ATPs which have energy in order for it to move something through the cell membrane. There are different types of transport to suit the sizes of molecules as well. Passive transport includes diffusion‚ osmosis‚ and

Lab 3 – Homework 1. Purpose of today’s experiment: To determine the effect osmotic pressure might have on cellular membranes‚ specifically when beet slices are placed in NaCl solutions of varying concentrations. 2. Hypothesis: The osmolarity will directly increase with increasing NaCl concentrations. 3. Control = Distilled Water – this was present in all solutions 4. The independent variable – salinity of the 6 solutions; while predetermined‚ the NaCl concentrations varied from 0% to 15%.
