principle‚ a purple onion cell is going to be bathed in different concentrations of salt (NaCl) water. Problem: How do solutions of various salt concentrations influence osmosis in relation to an onion cell? Hypothesis What will happen to the onion cell if it is placed in salt water? What will happen to the onion cell if it is placed in distilled water? If ..the onion cell is placed in salt water then... the cell will shrivel up The

Introduction Memory is defined as the faculty by which the mind stores and remembers information(Eysenck & keane‚ 2010). Atkinson and Shiffrin (1968) (Cowan‚ Rouder‚ & Stadler‚ 2000)‚ came up with a model of sensory memory which stated not everything we perceive we process. Craik and Tulving (1975) developed an opposing theory in which they proposed the levels of processing theory‚ stating its not the processing but the type of quality of the processing that is performed‚ that determines the retention

Job Safety Analysis or Job Hazard Analysis All employers have duty of care to individuals‚ staff‚ contractors or third parties in the workplace. It is also a legal requirement that organizations should document any health and safety risks that have been identified in the workplace. Equally‚ it is necessary to record the actions taken to reduce those risks What is a Job Safety Analysis or Job Hazard Analysis? One way to increase the knowledge of hazards in the workplace is to conduct

INTERPRETATION OF RESULTS: This experiment circles around with the Newton’s second condition of equilibrium in rotational motion. It describes by net torque acting on a body which is zero. The ability of the body to rotate in a certain direction is varied according on how much torque is applied. To prove that‚ a beam that is subjected to two forces is balanced by adjusting the perpendicular distances. When applied force is weight‚ modification in masses added is also done. Once equilibrium is achieved

EXPERIMENT 5 SEPARATION OF A MIXTURE INTO ITS COMPONENTS BY FRACTIONAL CRYSTALLIZATION Introduction: Fractional crystallization is one of the experimental techniques used to separate or purify mixture. Fractional crystallization makes use of the differences of solubility to separate the components of a mixture. Goals: Applying fractional crystallization to separate a mixture of salicylic acid and copper sulfate pentahydrate into its components. Calculate the percent of salicylic

Effect of enzyme concentration on rate of reaction Research question: is there a relationship between catalase concentration and the rate of reaction? Hypotheses: if the enzyme concentration is increased then the rate of reaction will increase. If the enzyme concentration is decreased then the rate of reaction will decrease.
