Her bicarbonate is very high; it should only be in the range of 22-28 mEq/L. Her pH is also high (alkaline); it should be in the range of 7.38-7.42. (“Normal Lab Values”‚ n.d.). The amount of potassium found in the urine can vary widely depending on the diet of the patient (Lee‚ 2013). So it in unknown as to whether her urinary potassium levels are within

SCIENCE - FORM 2 Nutrition CLASSES OF FOOD 1. Food is a basic necessity for all living things. 2. Food is important in order to : (a) Provide energy to carry out physical activities. (b) Provide energy for the physiological activities in life such as reproduction‚ digestion and excretion. (c) Build new cells and ti repair tissues in the body.

conditions such as under the bricks‚ woods and rocks‚ damp soil litter under the trees. Soils which are rich in calcium and other macro-decomposers (such as earthworms) generally have high number of slaters. These soils are usually in neutral or alkaline pH. As we known‚ acid soils have always limited the density of slater population because these soils may be lack sufficient calcium to enables them to build up their calcareous exoskeletons. In my initial trials of the slaters natural habitat‚ I

are protected from corrosion by the highly alkaline environment inside the concrete (pH≈13). If the pH decreases in the environment of the reinforcement‚ this protection ceases and the steel bars can corrode. Consequently‚ the rusting of the reinforcement usually leads to a severe reduction of the durability of the structure. One of the main processes facilitating the destruction of the protection by alkalinity is carbonation‚ i.e. the reaction of alkaline constituents of the concrete with atmospheric

Origin and Discovery: In 1969‚ Dr. John Opitz described two similar conditions that he called G syndrome and BBB syndrome. Further research suggested that these two conditions were one disorder but researchers could not agree on how this disorder was inherited. It wasn’t until 1995 that one type of Opitz syndrome was linked to 22q deletion syndrome. The 22q11.2 deletion is now thought to be the original cause of the medical problems for some patients with Opitz G/BBB syndrome. Symptoms and

How does acid precipitation affect marble and limestone buildings? Acid rain is a type of precipitation that is characterised by containing contaminating substances such as sulphuric and nitric acid‚ both of which have harmful effects on the environment. Both marble and limestone are extremely vulnerable to the damages done by acid rain due to their components. These materials contain calcite‚ a substance that easily reacts and dissolves with acid. Acid rain is the cause of the destruction of many

The Sperm and Egg Testes are suspended outside the abdominal cavity by the scrotum‚ a pouch of skin that keeps the testes close or far from the body at an optimal temperature for sperm development. Somniferous tubules are inside each testis‚ and are where sperm are produced by meiosis. About 250 meters (850 feet) of tubules are packed into each testis. Spermatocytes inside the tubules divide by meiosis to produce spermatids that in turn develop into mature sperm. Sperm production

Biology Form Four Digestion Digestion is the process by which food is broken down from complex insoluble substances into simple soluble substances. There are two types of digestion – chemical digestion and mechanical digestion. Mechanical digestion involves breaking up large pieces of food into smaller pieces. This provides a large surface area for the action of enzymes on food. There is no change to the chemical composition of food during mechanical digestion. Mechanical digestion occurs in
