order to equalize the level of water in each region. Involved in this process are hypotonic‚ hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure‚ indicating that the net movement of water moves into the said solution whereas a hypertonic solution is one with a higher osmotic pressure‚ thus the net movement of water will be leaving the hypertonic solution. Lastly‚ an isotonic solution entails no net movement of water across a semi-permeable membrane as the

these rays will worsen the severity of Mark’s sunburns. Henry should also start administering Mark diluted fluids that contain essential electrolytes‚ which to help restore hydration to Mark’s body without running the risk of his plasma becoming hypotonic from water intoxication. Mark has lost a lot of water through sweat and this combined with the intense heat of the sun has caused Mark to have heat stroke. The heat stroke and profound water loss is causing Mark to feel weak‚ nauseous‚ disoriented

The corn syrup is hard to say as it grey in mass but stayed the same in circumference‚ 13.5 cm‚ so the solution may either be an isotonic solution (Proving our second hypothesis correct) or hypotonic as it grew in mass. Their may be human error which affected the results such writing information incorrectly‚ messing up measurements‚ or using different types of materials than those needed. Many people may have also

is called a hypotonic solution and the low water concentration is called hypertonic solution‚ but these only depend on what type of concentration is on the other side of the partially permeable membrane. When more water passes through to one side of the membrane it is called net movement. (Toole + Toole "Essential AS level Biology") This is an example of the net movement through a partially permeable membrane. The right side is the more dilute solution‚ which makes it the hypotonic solution. The

Animation: Cells & Chemistry Glycolysis After viewing the animation‚ answer these questions. 1. Cells derive energy from the oxydation of nutrients‚ such as glucose . 2. The oxidation of glucose to pyruvate occurs through a series of steps called glycolsis . 3. How many carbons are in a molecule of glucose? 6 4. The energy related during these oxydation reactions is used to form adenosine triphosphate (

are solutions that also need to be discussed. Osmosis and diffusion are passive processes of transport (Human‚ p. 40). Isotonic solutions are solutions that contain the same concentration of solute particles per volume than that within the cells (Human‚ p.41). The same solute in ECF is also .9% NaCl of a normal concentration (McKinley‚ p. 112). There is also the aspect of a hypertonic solution‚ which means the concentration of solute is greater outside the cell then inside (Human‚ p. 41). There is also

In our Mediaphys Lesson I learned that the primary structure of a cell membrane is made up of a double layer of phospholipids molecules. The hydrophilic heads of the phospholipid molecules face outwards towards the water base solutions inside and outside the cell. The membrane is also made up of proteins‚ carbohydrate molecules‚ and cholesterol that form gates and pores‚ cell recognition‚ and stability. Active transport is used when a cell needs a substance to cross the membrane against its concentration
