of the big is osmosis‚ and how it had the overall impact in this excitement a little on osmosis. Osmosis takes place when two solutions of different concentrations are separated by a semi-permeable membrane in which the solvent can pass through but not the solute. In our experiment‚ we used a sucrose solution that will be a hypotonic concentration of solute. This tells us that the solution has a lower concentration of water than does the cells. Therefore‚ due to osmosis‚ the cells will gain water

Objective: To observe the effects of osmosis on eggs placed in vinegar (5% acetic acid)‚ syrup (60% sugar solution)‚ and water (100% distilled). Hypothesis: Hypothesis #1: It was hypothesised that the egg would gain 59 grams of mass after soaking in vinegar for 24 hours. Hypothesis #2: It was hypothesised that the egg would become larger when soaked in syrup than it once was due to the hypotonic environment. Hypothesis #3: It was hypothesised that the egg would soak in water for 72 hours‚ losing

Osmosis is the movement of water across a membrane. It always navigates to the area of the membrane with a higher solute concentration. We take a closer look at the effects of osmosis in this lab through the examination of red blood cells (sheep)‚ plant cells (elodea)‚ and active transport in yeast. Under the microscope‚ we can determine the effects on plant and animal cells exposed to hypotonic‚ hypertonic‚ and isotonic sodium chloride solutions. Plant cells have a cell wall; however‚ animal cells

Osmosis Experiment Subject: Professor Egg-avier Duration: 3 weeks (Oct 2nd – Oct 16th) Week 1 On October 2nd my group was giving a raw egg (weighing 58.8 grams) and placed it into a clear mason jar with 200mL of vinegar. The ph levels of our vinegar equaled a 2 which tells us that vinegar is a fairly acidic liquid. Once submerged in the vinegar‚ little bubbles began to appear around the egg’s shell. We believed this to be carbon dioxide escaping from the shell. We left our egg to sit in the

When you think of the word "drug" what comes to mind? Probably marijuana‚ cocaine‚ lsd‚ prescriptions but what about bath salts? When I first heard stories about people on bath salts my reaction was you have to be kidding right‚ but no first popping onto the radar of the DEA and poison control in 2010‚ this product is causing quite a stir in the United States. Mark Ryan from the LA poison control says in an interview on the Dr. Oz television show "that he has never seen a drug that has caused the

Osmosis is the net movement of water from a high concentration of water to a low concentration of water down a concentration gradient. This is done to equalise the solute concentrations on the two sides. Therefore‚ in other words‚ the movement of water is depended on the concentration of dissolved solute in the water (in this case the sucrose) and if there are a higher concentration of sucrose in the visking tubing‚ the water in the beaker will move into the visking tubing to make both solution balanced

Aim: To investigate the effect of hydrogen peroxide concentration on enzyme catalase Indroduction: Enzymes are proteins. They function as biological catalysts. They lower the energy barrier of a reaction so that the reaction can take place at body temperature. Also‚ they can speed up Metabolic reactions without being changed or used up. During a reaction‚ an enzyme molecule combines temporarily with the substrate. When the reaction is complete‚ the enzyme molecules returns to its original dorm

Grade 12 Biology (SBI 4U1) Nicole Mikulis Unit: Biochemistry Sept 14 2012 Lab: Effect of temperature and pH on catalase activity BACKGROUND Catalase is an enzyme that detoxifies chemicals that might harm the cell such as hydrogen peroxide (H2O2). The enzyme breaks H2O2 into water and oxygen. The production of the oxygen gas bubbles serves as evidence that the catalase enzyme is working. As catalase is breaking the bonds between H2O2‚ it is releasing energy in
