Water added to the polymer‚ unlinking the chain and breaking it back down to its original monomer units.

Amid high food prices in 1972‚ Sweden’s National Board of Health and Welfare developed the idea of "basic foods" that were both cheap and nutritious‚ and "supplemental foods" that added nutrition missing from the basic foods. Anna Britt Agnsäter‚ head of the test kitchen at KF‚ a consumer co-op that worked with the Board‚ held a lecture the next year on how to illustrate these food groups. Attendee Fjalar Clemes suggested a triangle displaying basic foods at the base. Agnsäter developed the idea

P5. Explaining the Concept of Homeostasis. M2. Probable homeostatic response’s to changes in the internal environment during exercise. The actual word homeostasis means "steady state". Homeostasis describes how the body regulates its process to keep its internal conditions as stable as possible. Homeostasis is necessary because human cells are efficient but very demanding. The phrase homeostasis is a bit confusing; conditions inside our bodies are not constant but are kept within a narrow

include a diverse group of plant foods that differ greatly in their energy and nutrients content‚ and form an important component of the human diet. They are excellent sources of nutrients‚ specifically essential vitamins‚ minerals‚ fiber and complex carbohydrate and also add variety to the diet all of which are needed to support a healthy body and mind (Slavin and Lloyd 2012). According to the World Health Report (2002)‚ low fruits and vegetable intake is estimated to cause about 31% of ischemic heart

of beet juice | Bluish-Black | Analysis: * From the experiment it was obvious that the starch solution was the positive control‚ while the distilled water was the negative control. * It was concluded that the iodine reacted to coiled carbohydrates. Conclusion: * At the end of this experiment I was able to conform and accept my hypothesis‚ since the positive control; starch‚ and the other rich in starch solutions turned to Bluish-Black

AS Biology‚ Biological Molecules Revision Notes Distinguish between monomers and polymers: Monomers- Identical small molecules. Polymers- Chainlike molecules formed from the linking together of many similar. Distinguish between monosaccharides‚ disaccharides‚ and polysaccharides: Monosaccharides- Simple sugars; sugar molecules may be enantiomers due due to the spatial arrangement of parts around asymmetric carbons; raw material for synthesis of other organic molecules. Disaccharides-

In fact‚ they are “almost polar opposites of each other”(4). The Mediterranean diet consists of fruits and vegetables‚ good oils and chicken and fish (4). The American diet however‚ is high in carbohydrates‚ sugars‚ bad oils‚ and red meats (4). Unlike the Mediterranean diet‚ the standard American diet does not put an emphasis on fruits and vegetables (4). American diet consists heavily of processed foods‚ fried and fast foods‚ red meats and bad oils

Title: Inhibition of Yeast Glycolysis Abstract: The purpose of this experiment was to study carbon dioxide emissions from yeast‚ as well as their respiratory rate and to use that data to study how glycolysis inhibitors affect the respiratory rate. In our experiment‚ we tested how 8.75% glucose + 1.25% NaCl‚ 8.75% glucose + 1.25% glucose-6-phosphate‚ 8.75% glucose + 1.25% citric acid‚ and yeast solution‚ all mixed with distilled water‚ affect carbon dioxide volumes and respiratory rate. Our results

Getting Lean With Carb Cutter? Many Americans have turned to diet pills. Should you? In the United States today many people have supposedly lost weight with certain pills. One of these pills is called carb cutter. Carb Cutter claims to inhibit the activity of the starch-digesting enzyme‚ amylase. When the diet pill binds to the amylase‚ it prevents the breakdown of starch. In the Biology 1103 lab‚ we conducted two experiments to determine whether or not the diet pill‚ Carb

Dr. David B. Samadi said that‚ “Many diabetics find that products with artificial sweeteners help curb cravings as sweeteners tend to be much more intense than regular sugars and having no carbohydrate or effect on blood glucose levels.” This is a plus for diabetics to have artificial sweeteners since most like to consume lots of sweeties. “It enables people that are carb‚ sugar or calorie conscious to take in a wider range of foods that they
