The Chicken Pox a.k.a. Varicella Virus Whether something serious as cancer or the common cold‚ each of these things started with a virus. Viruses come in many different forms. There are about 1 million different viruses and they are everywhere. A virus is a microscopic infectious agent that can replicate only inside the living cells of organisms. One of such is a virus commonly known as the Chicken Pox. The Chicken Pox is caused by a virus called ‘Varicella’‚ which is very contagious. Symptoms

Ahmed Salem 17/1/2011 Section 3 The process of Natural Importance Introduction Osmosis is when a fluid passes threw a semi permeable membrane. Moving from an area in which a solute such as salt is present in low concentrations to an area in which the solute is present in high concentrations. There are three types of osmosis: hypertonic is when there is high concentration and the cell has no water inside it (shrunk)‚ hypotonic is when there is low concentration and the cell has swelled up or

Diffusion and Osmosis Worksheet Diffusion is the movement of particles from areas of higher concentration to areas of lower concentration. It is a natural‚ random process. This means that it does not require extra energy input. 1a. These are pictures of molecules frozen at two different times. Draw arrows to show the direction each particle might travel due to diffusion in diagrams A and B. A. B. Random arrows Random arrows 1b. Describe the way the particles

Step 4: To create the 40% salt solution add 20 grams of salt to one cup. Measure the salt using the scale. Step 5: Add 0.2 grams of salt to the second cup. This is for the 0.4% salt water solution. Step 6: Leave cups to sit. Check on them next class and record observations. Sample Initial Mass (g) Day 1 Final Mass (g) Day 2 Quantative

Question 1: How does Osmosis works It refers to the movement of water molecules from an area of high-level water concentration‚ that is‚ a dilute solution‚ to an area of low-level water concentration‚ that is‚ a strong solution through a semi-permeable membrane. (Passmyexams.co.uk‚ 2015) Actually‚ water moves in a bi-directional manner with the aim of leveling up the concentration. However‚ a high number of water molecules move from the fresh water towards the salty water. The outcome

Egg Baby Project & Baby Think It Over Child Development Ms. Stump You are responsible for your egg baby and must take your baby everywhere you go‚ even to school! There will be a day care center in Room 225 for you to drop off/pick up your baby each day. Please read the requirements and consequences for not following them. This project lasts for four (4) days. You will be given class time to complete the project; you will also be responsible for caring for the baby outside of class. If

Green Eggs and Ham Growing up‚ it was common for children to be familiar with the well-known children’s picture book “Green Eggs and Ham” written by the famous author Dr. Seuss. This famous story was written “when someone challenged him to write a book using 50 words or less” (Baldassarro 2). The gist of the book “Green Eggs and Ham” is it is about a character called “Sam I Am.” Sam’s goal in the book is to try and get his roommate who is very grouchy and negative to try green eggs and ham in different

Boiled eggs; I believe all of you know boiled egg….. How many methods of preparing boiled egg is known to you? Today I am going to teach you a new method………. Using 4 mobile phones‚ 4 pre-recorded tapes & an egg Connect 4 mobile phones to pre-recorded tapes and keep them were live with an egg in the middle. After around 80 minutes‚ the egg will be found to be hard-boiled. This was an experiment conducted by Punjab University‚ India on impact of electromagnetic radiation of cell phones

DIFFUSION AND OSMOSIS Chapter 3 of your textbook explains diffusion and osmosis. Diffusion is simply the net movement of atoms or molecules from a region of higher concentration to a region of lower concentration. The force behind the movement is heat or kinetic energy (also called Brownian motion). Diffusion occurs when you spill water on the carpet floor and it spreads out‚ or when you open a bottle of perfume and it leaves the bottle and spreads throughout the air in the room. Osmosis is a similar

and air as the control. When performing this experiment‚ the main element to consider is hypertonic‚ hypotonic and isotonic solutions and how they relate to osmosis. Osmosis is the process where a fluid passes through a semipermeable membrane‚ which moves from an area which the solute is present in high concentrations. As a result of osmosis‚ there will be an equal amount of fluid on either side of the barrier‚ creating an isotonic solution. When cells are placed in an isotonic solution‚ the movement
