Practical 2: Observation of mammalian kidney model and tissue slides. Analyzing kidney filtration using simple filtration system Introduction: Kidney is part of mammalian’s body endocrine system. Every mammals have a pair of kidneys that is located at the middle back of the body and symmetrically beside the spine and below the rib cage. A kidney approximately 0.5% of the organism body weight. Every kidney will receive huge amount of blood to enable them to perform important task. The base unit of

Plan a procedure that will allow you to compare quantitavely the glucose concentration in fresh samples of orange‚ lemon and grapefruit juice. Aim: The aim of this investigation is to produce a set of data which will enable comparison of the glucose concentrations of orange‚ lemon and grapefruit juice. Research: Benedict’s Reagent is a mixture of sodium compounds and copper sulphate. The copper ions are reduced by fructose (a reducing sugar) to form copper oxide‚ thus turning it from blue

Abstract Literature on Van’t Hoff’s law states that water potentials and zero weight change osmolalities will be the same for potato cores placed in varying concentrations of solutes of NaCl‚ glucose‚ and sucrose. This experiment was designed to test these predictions and compare them to data gathered course wide. We found that the mean water potentials were all within 0.26 bars of each other‚ and that the zero weight change osmolalities were all within 0.035 mols of each other. This supported Van’t

Laboratory Order Form 1 DESIGN 1.1 Defining the problem Focus / Research question How does osmosis work and what effect will this have on the raisin at different sucrose concentrations? Hypothesis The raisin in the beaker with most diluted sucrose solution will gain the most mass‚ therefore the control (0% sucrose solution) should be the most successful (in relation to the aim.) Background Information / theory Osmosis may occur when there is a partially permeable membrane‚ such

overall impact in this excitement a little on osmosis. Osmosis takes place when two solutions of different concentrations are separated by a semi-permeable membrane in which the solvent can pass through but not the solute. In our experiment‚ we used a sucrose solution that will be a hypotonic concentration of solute. This tells us that the solution has a lower concentration of water than does the cells. Therefore‚ due to osmosis‚ the cells will gain water weight also proven in the experiment given. If

converted to sugars through a process that is known as fermentation. Sugars in the form of sucrose are mostly used by humans (Alexander N.Glazer). Sugar cane and sugar beet are composed of 20% sucrose‚ 75% water‚ 5% cellulose and about 1% is inorganic salts (Alexander N.Glazer). Sucrose is extracted with water by using mechanical pressure from the sugarcane. On the other hard the beet is peeled and crushed. Sucrose that was extracted from sugarcane is a highly effective substrate that is used during

concentration of 1-kestose isomer increased steadily with time from 0 - 80 min. During this time‚ sucrose was significantly influencing the rate of 1-kestose formation and hence the optimum concentration of the 1-kestose isomer was observed at 80 min. After 80 min‚ the 1-kestose concentration gradually decreased. This was because the invertase active sites had become saturated with sucrose (substrate) or sucrose had been used up in the reaction. Therefore‚ there was a gradual decrease observed in the
