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

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

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 (

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

Lipids and Phospholipids The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The head which is hydrophilic contains a group of phosphate‚ a diglyceride and a simple molecule e.g. choline. The tail is hydrophobic and is made up of fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The

When Different Colors of Food Coloring Are Soaked into a Naked Egg‚ Will the Mass Change Depending on the Color of the Ink after 7 Days? The Purpose The purpose of initiating this lab was to test how different chemicals in the outer fluid affects the osmotic properties of a naked egg. Background Information In order to complete this experiment‚ one of the most important things you need to know how to do is how to take the outer “shell” layer off of the egg. The egg shells contain an element known
