The Effects of Heat on the pH of the Vegetable and Their Pigment PURPOSE The purpose of this experiment is to see how pH levels of certain vegetables change while being cooked in four different mediums (frying‚ boiling‚ steaming‚ roasting)‚ and how the varying pH levels change the coloring of the vegetables. We will analyze how the different method of cooking/heating changes the levels of pH. BACKGROUND INFORMATION This experiment is based around the different pigments in vegetables‚ of which

strength 1M HCl acid had a pH level of 3.12 (Table 3.1). Sample A2 to A4 remained in the pH 3 level‚ while sample A5 and A6 had a pH range of 4 (Table 3.1). The pH level for 1M HCl dilutions slightly increased between each sample (Table 3.1). The diluted solutions of 1 M NaOH showed a few unexpected results. The original solution of 1 M NaOH was at a pH level of 11.50 (Table 3.1). However‚ the pH of sample B2 increased to 12.81 (Table 3.1). The remaining samples had a decreasing pH pattern for each dilution

Blood sugar levels and dementia: how our diet could be leading to memory impairment Dementia and memory loss is of major concern for all of us. It is estimated that 35 million people worldwide suffer from Alzheimer’s disease and it has been proposed that this number will grow to around 100 million within the next thirty years (Copped’e‚ 2012). Although‚ it has previously been established that an important risk factor of dementia is diabetes (Bijal‚ 2012)‚ new evidence now suggests that sugar intake

AbstractDifferent pH level may affect the growth and development of the plants. Certain key words include: pH level‚ germination‚ acidity‚ osmosis and diffusion. This experiment examines the effects of different pH level of vinegar on the growth of bean plants. Materials used in this experiment consist of: water (pH 6)‚ vinegar with the pH level of 3‚ 4 and 5 (each one were made before experiment)‚ beans‚ soil‚ and pots. Eight bean plants were planted‚ two were watered with pH 6 and the other ones

Imagine having nonstop growing fat on your stomach. That is what happens with Gaucher’s Disease. Gaucher’s is when your recessive gene gets duplicated and the metabolism gets built up with fat called glucocerebroside and it can’t be degraded‚ you can’t get rid of it. Some of the major causes are enlargement of the stomach or spleen. You can also have a low amount of red blood cells. Some symptoms of this disorder are easy bleeding or bruising‚ extra fat on stomach‚ bone and joint pain‚ and weak bones
