Chris Jostad NRS 111 4/4/13 Case Study 76 1. * Fasting glucose: 184 mg/dL-above 99 mg/dL suspected diabetes mellitus among other etiologies * HbA1C: 8.8%-The American College of Endocrinology recommends and A1C less than 6.5%. An A1C of 8.8% would also indicate diabetes mellitus. * Total cholesterol: 256 mg/dL-total cholesterol above 200 mg/dL could indicate uncontrolled diabetes * Triglycerides: 346 mg/dL-levels above 150 indicate diabetes mellitus * LDL: 155 mg/dL-Increased

Osmosis Lab Report Hypothesis: Osmosis will occur when there is an uneven distribution of solute in a solvent. The higher the solute in solvent‚ then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Materials: Distilled water‚ sucrose‚ dialysis tubing‚ string‚ 250 ml beaker. Procedure: To demonstrate and isotonic solution we needed 3 inches of dialysis tubing. We

OSMOSIS IN POTATO TISSUES Vanessa Tsao‚ Lovette To‚ Wang Yeyun‚ Zhang Shenjia‚ Alicia Mak Class 101‚ Nanyang Girls’ High School‚ 2 Linden Drive‚ Singapore 288683 ABSTRACT In this project‚ the relationship between the concentration of salt solution and the length of the potato strip that was immersed in it was investigated. Five strips of potato of the same length were placed in different Petri dishes that contained water of different salt concentration. They were left for twenty minutes and the length

within a cell are called Diffusion. When molecules move across a cell membrane it is known as Osmosis. Diffusion is the process by which molecules of a substance move from areas of higher concentration of that substance to areas of lower concentration. Diffusion can be the transfer of anything anywhere. However‚ that is not true for osmosis. Osmosis is diffusion‚ but a specific type of diffusion. Osmosis is only the diffusion of water molecules through a selectively permeable membrane and a concentration

Investigating the effect of different concentrations of glucose on the percent change in mass of Gummy bears according to their respective colours In this experiment osmosis is the main process taking place. Osmosis is the diffusion of water molecules of a solvent which pass through a semi permeable layer and in most cases are due to a concentration gradient meaning that the water molecules travel from an area of low concentration to one of higher concentration. In this investigation‚ gummy bears

Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around
