ACTIVITY 1 Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. __The size and the concentration. ___ 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? __ The molecules were to large to go through. My results matched._ 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your

2.1.1 Conclusion 1 Describe how Glucose Tolerance Testing can be used to diagnose diabetes. Test is also used to diagnose the presence of gestational diabetes and type 2 diabetes. With IGTT‚ glucose is injected into your vein for 3 minutes. Blood insulin levels are measured before the injection‚ and again at 1 and 3 minutes after the injection. The timing may vary. The oral glucose tolerance test is used to screen for‚ or diagnose diabetes in people with a fasting blood glucose level that is high

2. The novel takes place‚ as its title suggests‚ in two cities: London and Paris. What are some of the differences between these two cities? Between their denizens? What about characters who travel—or move residence—from one to another? How are the cities themselves divided in two? In the first chapter of Tale of Two Cities Dickens states that “There was a king with a large jaw and a queen with a plain face on the throne of England; there was a king with a large jaw and a queen with a fair face

Diffusion in Cells Isabel Zak Question: How does the size of a cell affect the distribution of chemicals throughout the cell? Hypothesis: The larger the cell is‚ the more difficult it will be for the chemicals to reach the centre of the cell‚ and diffuse throughout it. This is because there will be a higher surface-area to volume ratio in the larger cells‚ making the centre of the cells further away from the surface. Therefore‚ when dipped in sodium hydroxide‚ the larger cells will not be

on chemistry. Cells are considered to be the smallest structure that is alive. They are often too small to see without the aid of a microscope. All living organisms are composed of cells. The smallest organisms are composed of a single cell; larger organisms are composed of more than one cell. Similar kinds of cells may be arranged together to form a tissue. Tissues have specific properties and functions. For example muscle tissue is composed of muscle cells. It functions to move body components

transmission in Caenorhabditis elegans Introduction A nerve cell is made up of three main structures: the soma‚ the axon and the synapse. When a nerve cell receives a signal‚ a protein called kinesin travels anterograde along the axon and guides the synaptic vesicles until it reaches the synapse. This triggers the release of the neurotransmitters stored within the vesicles. Once released‚ the neurotransmitters then bind to receptors of the receiving cell. It would be nearly impossible to have the transportation
