The rate of fermentation is faster when there is more sucrose concentration because it means there is more glucose‚ which in return means more carbon dioxide production. The sucrose concentrations were 0%‚ 1%‚ 5%‚ and 10%. The 0% sucrose concentration is just normal‚ plain water. Yeast‚ a single celled eukaryotic fungi‚ was put into the solutions. It uses fermentation to make more carbon dioxide and alcohol. In the 0% solution‚ no carbon dioxide had been produced. At the start‚ the depth of the

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 to a brick red/orange precipitate

In Unit 5 Activity 2 we were asked to predict and then find the brightness and flow rate of a closed circuit with a three cell battery pack‚ a long bulb‚ a capacitor parallel to the long bulb‚ and a round bulb. I originally predicted that the round bulb would be brighter when the circuit was first closed and when the circuit reached a steady state‚ and that the wire between the round bulb and the negative side of the battery would have a higher flow rate than the other wires. However‚ in the steady

ACTIVITY 5 Exploring Various Breathing Patterns You will establish the baseline respiratory values in the first part of this experiment. 1. If the grid in the data control unit is not empty‚ click Clear Table to discard all previous data. 2. Adjust the radius of the airways to 5.00 mm by clicking the appropriate button next to the Radius window. Now‚ read through steps 3–5 before attempting to execute them. 3. Click Start‚ and notice that it changes to Stop to allow you to stop the respiration. Watch

(Tzahi 2006) To demonstrate osmosis lab‚ artificial cells were made with various sucrose concentrations and were placed into beakers of different sucrose solutions. Overall the results showed that the higher percentage of concentration gradient of sucrose‚ the more the artificial cells absorbed. Introduction: The phenomenon being investigated in the lab was how the concentration gradient

Clèo from 5 to 7 is a film written and directed by Angnès Varda; it follows Clèo‚ a young singer in Paris as she anticipates the result of her medical test. The film’s use of cinematography techniques such as tracking‚ the use of a handheld camera‚ and zoom lens all exemplify the notion of ignorance; being unaware‚ oblivious and lacking in perspective. At the very start of the film‚ the viewer is greeted with the concept of death. In this scene‚ Clèo visits a fortune teller who reads cards; she

experiment that estimates osmolarity by change in weight of potato tubers‚ this was conducted in order to explore the process of diffusion and osmosis and more importantly to investigate the question of “Does different concentrations of sucrose solutions have an effect on the final weight for the potato tubers?” In this experiment we estimated the osmolarity of potato tuber cores by submersing different potato cores into sucrose solutions of 0.0-0.6M‚ and weighing the potato. The results showed the weight
