of different concentrations of saline solution on Red Blood Cells. When a Red Blood Cell is submersed in a high concentration of saline solution it will create a hypertonic environment and therefore cause the cell to rupture due to the process of osmosis. The methods used to collect data were observation and note taking. Overall the results proved the hypothesis correct with major findings being a higher concentration of salt causing a hypotonic environment and a low concentration. Recommendations

Introduction: Diffusion and osmosis are passive processes of transport. Passive transport involves no disbursement of energy by the cell. Diffusion movement is from high concentration to low concentration‚ which the driving force for this type of movement is kinetic energy particles themselves. Which crystal (Methylene blue‚ solid or Potassium Permanganate KMnO4-purple) will move further than the other due to the driving force (kinetic energy)? My prediction is that Potassium Permanganate KMnO4-

Refined sugar is unhealthy when consumed in large amounts and there are healthier options. Refined sugar has no nutrition. There are also many health risks when sugar is over consumed. Humans need carbohydrates to survive but there are many healthier way to get them than too many cookies or soda. Simple sugar is made of two components. They are mainly fructose and glucose(Dubost‚ June 12‚ 2013). Sugar is naturally produced in plants during photosynthesis. It is found naturally in milk‚ fruit‚

The Effect of Concentration Gradient on Osmosis Abstract: Osmosis is the passive movement of water from an area of higher concentration to an area of lower concentration‚ usually across a membrane (Thorpe 2013). Tonicity is the ability of a solution surrounding a cell to gain or lose water (Reece 2011). There are many factors that affect the rate of osmosis. These include temperature‚ surface area‚ difference in water potential‚ pressure‚ light and dark and most importantly what we will be talking
Premium Diffusion Solution Water pollution
Diffusion‚ Osmosis and Active Transport Substances will move through the membrane by diffusion. This is the random spreading out of particles until they are even. For example‚ when you put your instant coffee in boiling water‚ the coffee particles spread out and fill the entire mug‚ this is diffusion. A second way that substances can move through the cell membrane is by osmosis. This is a special type of diffusion where water moves from a high to a low concentration through a ’partially permeable

are many that are more common that a majority of people face whether they realize it or not‚ such as an addiction to sugar. In our current society‚ we are constantly surrounded by sugar as it is in almost all of the food we eat whether it be a small or large amount. Due to this‚ one is constantly consuming sugar and does not even realize that they are addicted to this substance. Sugar is an addictive substance because when consumed it causes one to crave more‚ makes one become dependent upon it‚ and

What is Sugar? What is sugar? Something very tasty? Something that makes you delighted? That is true‚ but more importantly sugar is very addictive‚ awful for your teeth‚ and your whole body over all. Sugar is a very dangerous object; it can cause tooth loss‚ liver damage‚ heart attacks‚ diabetes‚ weight gain‚ and other problems with the body. The whole population on earth should start limiting the amount of sugar it consumes. II. Sugar is important for the human body and the brain. Sugar from a few

Making mashed potatoes from scratch Are people always buying boxed or premade mashed potatoes because making them homemade is too hard? This is the discovery that it’s not that hard to create a very tasty homemade mashed potatoes. Of course it takes a little more work than dumping a package into a pot or microwaving something from the freezer. However‚ the cook will prepare homemade mashed potatoes and have the satisfaction of knowing they were made from scratch. Preparing mashed

In today’s society‚ sugar is just another product that is used daily but what we don’t know is the bad side of sugar. Sugar was the product that created the slave trade. It was an addiction to people and a nightmare for slaves. It caused a lot pain and killing but it also brought sweet taste in food. Sugar comes from a crop called sugar cane. Sugar can is a native crop to Polynesia and later on moved to China and India. It was widely used in India and in China sugar cane was chewed during 1000

Wierzchon A.P. Biology Lab: 1. Osmosis 09/10/2010 I. Introduction a. Purpose: The purpose of this lab was to observe the diffusion process of water‚ osmosis‚ as well as create an understanding of water potential‚ the basis of osmosis. The experiment proved how water molecules in a solution are able to move from an area of low solute concentration‚ high water concentration‚ to an area of high solute concentration‚ low water concentration‚ diffusing “down” the water gradient. The movement of
