Abstract This experiment was designed to answer the question does temperature affect the amount of osmosis? The hypothesis predicted was that the higher the temperature the more osmosis would occur‚ but too high the osmosis would halt due to enzyme and substrate overheating and losing shape. After research and class time it was concluded that osmosis is a passive transport and would not require energy or enzymes due to it going from high to low concentrations with the gradient

aspects that need to be considered during the experiment are to provide caution whilst handling benedict’s solution as it can be caustic to the skin and eyes. As a safety measure wear a lab coat‚ gloves and protective goggles at all times . Handle glass ware with care to minimise breakage. Follow general lab practice. METHOD The apparatus was

1. Which tool is better at performing protocol captures and which tool is better at performing protocol analysis? Net witness Investigator is best at performing protocol captures and Wireshark is better at performing protocol analysis. 2. What is promiscuous mode and how does this allow tcpdump‚ Wireshark‚ and Netwitness Investigator to perform protocol capture off a live network? “Promiscuous mode is a mode for a wired network interface controller (NIC) that causes the controller to pass all

the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement of water across a selectively permeable membrane. In osmosis‚ water diffuses across the area of lower solute concentration to that of higher solute concentration until the solute concentrations of the environment and the cell are equal. Tonicity‚ which is the ability of a solution to gain or lose water due to osmosis‚ results in an environment that is isotonic‚ hypertonic‚ or hypotonic

In this experiment‚ we had to demonstrate the process of osmosis using potatoes‚ and to determine the concentration of the cytoplasm of the potato. To demonstrate this‚ we had 6 test tubes and poured in different sucrose solutions of the following concentrations: 0.0M‚ 0.1M‚ 0.2M‚ 0.5M‚ and 1.0M. Once added in with all the sucrose solutions‚ we added in the 6 cylindrical potatoes of equal diameter and length. Before and after putting it in the potatoes‚ we had to weigh the initial and the final mass

Unit 7 Lab 7: Performing a Business Impact Analysis for an IT Infrastructure IS 3110 Debra Williams 1. What is the goal and purpose of a BIA? a. The purpose of a business impact analysis (BIA) report is to describe the potential risks specific to the organization studied. One of the basic assumptions behind BIA is that every component of the organization is reliant upon the continued functioning of every other component‚ but that some are more crucial than others and require a greater allocation

cell wall surrounding them. When the take up water by osmosis they start to swell‚ but the cell wall stops them from bursting. When they are put in dilute solutions‚ plant cells turn out to be “turgid” (swollen and hard). When the pressure inside the cell increases; No more water can’t enter the cell because the internal pressure of the cell is really high. “When plant cells are placed in concentrated sugar solutions they lose water by osmosis and they become “flaccid”; this is the exact opposite

Lab 7: Catalysts Introduction Pre-Lab Questions 1. What is a catalyst? An enzyme is a biological catalyst that speeds up chemical reactions in the body. 2. If you continue to add more catalyst will the speed of a reaction always continue to increase? Explain your answer. It will continue to speed up the reaction until there is more catalyst than the limiting reactant. 3. In this lab you will produce oxygen and water from hydrogen peroxide (H2O2). Write a balanced reaction equation for this reaction

Potato osmosis report Operators Introduction The purpose of the liberation Liberation is to understand what is happening with the potatoes when it is in the water. To find out how osmosis takes place and what it ’s purpose as well as other examples of osmosis. The experiment is to understand what is happening with the potatoes when they are in the water and understand the osmosis process occurs.
