Basic cooking principle CONDUCTION Conduction occurs in two ways: 1. When heat moves directly from one item to another part of item example‚ from the top of the range to a soup pot placed on it‚ from the pot to the broth inside‚ and from the broth to the solid food items in it. 2. When heat moves from one part of something to an adjacent part of the same item for example‚ from the exterior of a roast to the interior‚ or from a sauté pan to its handle. Different materials conduct heat at different

Why do you think there was no pressure change? You correctly answered: c. There is no net movement of water because the solute concentrations are the same.

substances will move passively through a deferentially permeable membrane depending on the concentration differences. We used PhysioEx software to examine diffusion. In these experiments we used different sized membranes as well as NaCl‚ urea‚ glucose‚ albumin‚ powdered charcoal‚ and KCl. The step by step process was used by the software so that we could see the different kinds of reactions. According to the data found‚ we found that with high molecular weight compounds are too large to penetrate the molecular

ERYTHROCYTE SEDIMENTATION RATE | -AND ITS VARIATION | | ABSTRACT: The Erythrocyte Sedimentation Rate (ESR)‚ also branded as sedimentation rate or Biernacki Reaction‚ is the rate at which red blood cells sediment in a time of 1 hour. To execute the test‚ anti-coagulated blood is positioned in an erect tube‚ known as a Westergren tube‚ and the rate at which the red blood cells fall is calculated and accounted in millimeters per hour (mm/h)

Insoluble in water lipids can be defined. To move lipids like fatty acid‚ triacylglycerols‚ steroids and fat soluble vitamins within the blood plasma‚ a mover protein is needed. Moved from the adipose tissue to the muscle‚ heart and liver tissues by serum albumin are fatty acids. Moved by the retinol binding protein is Vitamin A. There are steroid moverproteins that move steroids to the aimed cells. Majority of the body’s lipids(phospholipids‚ triacylglycerols and cholesterol)‚ are moved in the plasma

CHAPTER NO.1 INTRODUCTION HYPERTENSION: INTRODUCTION: This means abnormally elevated blood pressure. It may refer to increase blood pressure in any blood vessels‚ such as pulmonary or portal hypertension. However‚ it usually refers to an elevated systemic arterial blood pressure. Hypertension is not a disease but physical finding. 1.1 DEFINITION: Hypertension may be define as either a sustained systolic blood pressure (SBP) of greater than 140 mmHg or a sustained diastolic

a desired solute (serum‚ urine‚ chemical solution‚ etc.) contained in a solvent (diluent). A 1:10 dilution of serum was made by adding one part serum to nine parts diluent to make a total of ten parts. If 1.0 milliliter of serum is added to 9.0 milliliters of H20‚ a total volume of 10.0 milliliters is obtained. Therefore‚ the dilution is expressed according to the following equation. volume of serum/volume of solution = [1.0 mL serum ]/[1.0 ml serum + 9.0 mL H20] 1.0 mL serum/10 mL solution =

purpose of this lab was to look for different solutes that can cross an artificial membrane and to observe the effect of different concentrations of sucrose on the mass of a potato cell. Results for Part One suggested that the molecular weight of albumin and starch was too large to pass through the dialysis tube‚ but glucose and sodium sulfate molecules were small enough to pass through the dialysis tube. Also‚ a decrease in water weight occurred due the dialysis tube being placed in a hypertonic

Recall that glucose is a monosaccharide‚ albumin is a protein with 607 amino acids‚ and the average molecular weight of a single amino acid is 135 g/mole. Which of the following will be able to diffuse through the 200 MWCO membrane? Your answer : c. glucose only Stop & Think Questions: The reason sodium chloride didn ’t diffuse left to right is that You correctly answered: c. the membrane pore size was too small. Glucose is a six-carbon sugar. Albumin is a protein with 607 amino acids. The average
