membranes with little difficulty. This process is known as osmosis. The direction of motion is regulated by the relative concentrations of water and dissolved substances inside and outside the cell. Water will move from an area of high concentration of water molecules (low concentration of dissolved particles) to an area of low concentration of water molecules (high concentration of dissolved particles). It is difficult to observe osmosis at the cellular level since cells are very tiny and can only

This can be observed by looking at the values in table 2.0 and the trendline on grade 2.0. The trendline displays a positive slope‚ thus dictating a positive relationship between catalase concentration and the rate of reaction. This means when catalase concentration increases‚ the rate of reaction also increases. In other words‚ at 20% catalase concentration‚ the rate of reaction was only 4.220 mm/s while at 100% catalase concentration‚ the rate of reaction was 7.704 mm/s. This proves the positive

Sodium‚ one of many elements in the periodic table is being used in everyday life‚ it is also an essential element within your body. It is just another element‚ but one of the differences is that this element is something that most people consume every day. Sodium has played an important role in everyday life because of its uses in medicine‚ industry‚ and agriculture(Shriver). Sodium was discovered in 1807 by a man named Sir Humphrey Davy. He was well known for his discoveries of most alkali metals

Does cleaning a table tennis racket and keeping it in a case preserve its power and spin? Introduction: Spin plays a large part in most‚ if not all‚ ball sports. In no sport is the Magnus Effect more conspicuous than in the sport of table tennis. The small‚ light ball can spin up to 150 revolutions per second in a match situation. (Qun‚ et al.‚ 1992) This is due largely to technique‚ but the level of spin has greatly improved since the 1950’s‚ due to the invent of “sandwich rubber”‚ or “Inverted

Internal assessment on enzyme concentration Enzymes are proteins that act as catalysts and they are the most important type of protein. My aim in this experiment was to investigate the effect of enzyme concentration on the rate of an enzyme (protease) – catalyzed reaction ‚ catalysts speed up chemical reactions . My hypothesis is that the rate as reaction will increase as the concentration of protease in the solution increases so it will take less time for

Tables of Normal Values (As of January 2013) Note: Values and units of measurement listed in these tables are derived from several resources. Substantial variation exists in the ranges quoted as “normal” and may vary depending on the assay used by different laboratories. Therefore‚ these tables should be considered as directional only. Some values (e.g. hormones) vary by gender‚ age‚ time of day and condition (e.g. pregnancy) so a text on endocrinology should be consulted for complete data
