Lab Report One Exercise Five Activity One “Simulating Simple Diffusion” Activity Two “Simulating Facilitated Diffusion” Jessica Ogola Anatomy and Physiology 2401 Dr. Denyse Jones 02/02/2012 Objective: The objective of this experiment is to perform the simulation of the movement of solutes from a higher concentration to a lower concentration within a given amount of time. The goal of the exercise is to provide a simulation for the process of the facilitated diffusion of

Discussion: We have made four set-ups in two different specimens. Onion and Boat of Moses skin with water‚ 2%‚ 5% and 10% salt (NaCl) Solution. Based on our experiment‚ the result of the set up explains that the presence of the salt solution results in outward diffusion of water and the collapse of the protoplast. In table 1‚ we have observed under the microscope that the onionskin mounted with water has no results of plasmolyzed cell (0%). This time‚ we have repeated the procedure with 2% salt

During the Toxicity of Morton Salt on Radish Seeds experiment‚ we measured the levels of iodized Morton Salt to the growth rate of radish seeds. Each six packets had ten radish seeds with different level of iodized salt solution. The packet with no iodized salt solution grew the longest in a period of days‚ compared to the other packets that had iodized salt. Solutions 100% and 10% had no growth progress within the past five days. As for solutions 1%‚ .1%‚ and .01% grew‚ yet not as much nor fast

Nicoleta Nedelcu Caffeine-induced effects on heart rate in zebrafish embryos and possible mechanisms of action Observation Caffeine is found in coffee‚ tea leaves‚ cocoa beans‚ and kola nuts. It is used in prescription and over the counter drugs. It increases blood pressure‚ mental alertness‚ and gastrointestinal motility. Cardiovascular development with caffeine and other small molecules can be studied relatively easy using zebrafish. The cardiovascular system is complete in two days after fertilization

Semester One EEI Water Movement In Plants Jason Ho Ms Butz Group Members: Daniel Turner‚ Long Nguyen 13/05/10 Abstract The objective of this investigation was to determine the effect of one specific environmental condition on the rate of transpiration in plants. This particular investigation looked at the number of leaves in a plant and how it would affect the rate of transpiration in plants. The aim of this investigation was to find out if the larger the number of leaves

Noel Arackal 1.25.16 Bisc 4930 Experiment No. 1 – Varying Extracellular Concentration Introduction: This experiment sets out to determine the tonicity of solutions with varying concentrations of sodium chloride on the red blood cells of sheep by measuring the transmittance of a red blood cell/NaCl solution with a spectrometer. This is done in order to study the effects of solutions containing varying levels of tonicity to red blood cells. Tonicity describes what happens to a cell when it is

The experimental results were different from the hypothesis because while the enzyme appeared to not work as well‚ I expected a more significant change. Most of the time‚ there was only a millimeter of difference of the foam between the two samples while I expected a greater difference such as 10 millimeters. Enzymes speed up chemical reactions and at the active site‚ a substrate can be broken down or two substrates can form a larger molecule. Hydrogen peroxide is broken down by peroxidase into water

The detail of Morris water maze is as follows. 1. Preparation 1) A circular pool with a diameter of 150cm and a depth of 50cm. Use a white pool for black mice and black pool for white mice. The interior surface of the pool contains high contrast spatial cues‚ and they are above the water surface. 2) The test room are separated so that the animal being tested cannot see the observer during the test. 3) Put a 10cm diameter white platform in the white pool. Fill the pool with room temperature water

My results to my findings to my brine shrimp experiment was started on 12-28-15‚ using 4 jars. Each jar contained water‚ salt‚ and brine shrimp eggs. I started by filling each jar with tap water and then adding salt. I added 1 TSP of salt and each jar added ½ TSP more of salt. In my experiment I noticed on the first day‚ 12-28-15‚ in all the jars the brine shrimp eggs were added to the 4 jars. Some observations I noticed were the eggs didn’t sink right away‚ they stayed on the surface for awhile
