120-902 Grand Valley State University 1 Campus Drive Allendale‚ MI 49401 mcraeal@mail.gvsu.edu Abstract In this study‚ we tested the validity of osmosis in artificial animal cells. Osmosis is the diffusion of free water across a membrane. The purpose of the study was to calculate the rate of osmosis in artificial cells containing different concentrations of sucrose and water. We studied the rate of osmosis in artificial cells by creating five different

Experiment 1 Background Diffusion is a process‚ in relation to the spontaneous movement of molecules from an area of high concentration‚ to an area of low concentration down a concentration gradient. It is a type of passive transport method‚ that requires no cellular energy (ATP). This movement occurs‚ until a state of equilibrium has been established on both sides of the membrane. The diffusion of molecules happens at cellular level‚ through a cell membrane via the pores. The cell membrane

Emily Rose Gottsman Ms. Hicks ATC- Period 1 10 September 2014 A Steak The filet mignon served at Flemings Prime Steakhouse‚ is the most well-prepared steak in San Antonio. Almost everyone that lives in this city knows about this restaurant‚ located in an area called the Quarry‚ because it is in the middle of many neighborhoods. Many people claim that Fleming’s has the finest slices of meat they have ever tasted‚ because at any other steak house‚ the meal is just average‚ along with the service.

AP Bio Lab Report Osmosis and Diffusion Introduction When a substance is released into an area‚ the random movement of its molecules results in a multitude of collisions. These collisions‚ in turn‚ lead to a dispersion of the molecules. The overall movement of the molecules will be from an area of high concentration‚ where there will be more collisions‚ to areas of low concentration‚ where the number of collisions will be much less. This process of dispersion will continue until there is no

How To Grow A Garden It takes a lot of time and hard work to grow a garden. First you would have to start out small. You don’t want to bit off more than you can chew‚ or hoe. Like ‚ if you plant a huge garden‚ you’ll wish that you didn’t because of the hard work. Next‚ you must choose a location that receive as much sunlight as possible throughout the day. After you have located a spot to grow your garden‚ you should examine the soil. You will want to see if the ground is rich in top soil. Sometimes

The “Couch Potato” Lifestyle “Couch potato”‚ a slang term to describe a person who spends most of the time sitting or lying on a couch. However‚ sedentary lifestyle is another term which commonly used as a medical term to describe a lifestyle with irregular psychical activities or exercise. People intend to spend more time sitting‚ surfing the internet‚ working on a computer‚ watching television‚ and other activities that do not require much psychical movement or activities. Hence‚ this lifestyle

4.4.2 Viscosity Viscosity of a soup measured the internal friction of the soup or its tendency to resist flow (Chavan et al.‚ 2015). The result for viscosity of mushroom soups that analysed by viscometer (Brookfield model DV- Π + pro‚ America) was tabulated in Table 4.2. Viscosity of mushroom soup were significant different among different drying methods (p< 0.05). Fresh mushroom had lowest viscosity (750.50 ± 0.71 mpa.s) as compared the soup made from powders. Higher viscosity of mushroom soup
