colour leak out of beetroot? Procedure to investigate the effect of temperature Hypothesis- The higher the temperature while cooking the beetroot‚ the more pigments well leak out from the cell membrane‚ hence the absorbance would increase. My hypothesis was concluded by the facts that beetroot contains red pigments called betalians which are located in the cell vacuole. Normally the pigments cannot leak out; however cooking the beetroot allows the movement. This is because the cell membrane selectively

Comp II June 2nd‚ 2013 ------------------------------------------------- Using a Cell Phone While Driving: It Can Wait In recent years‚ a new and extremely dangerous epidemic has plagued our roads. The use of cell phones while operating vehicles is an ongoing controversy that is resulting in more and more deaths each year. Consequently‚ we are now dealing with much more than the occasional switch of a radio station‚ or a casual conversation with a passenger; we are faced with constant preoccupation

SEMESTER- I PRACTICAL- I VOLUMETRIC ANALYSIS The method to determine the exact amount of the substance in a given sample is termed as quantitative analysis volumetric analysis is a branch of quantitative analysis involving accurate measurement of volumes of reacting solutions. The volumetric analysis is very much in use due to simplicity rapidity accuracy and wide applicability. The reacting substances are taken in the form of solutions and made to react. The concentration of one solution is

Introduction Spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.[1] It can measure any of the listed light ranges that usually cover around 200 nm - 2500 nm using different controls and calibrations. [1] There are a few types of spectrophotometer such as calorimeter‚ UV spectrometer‚ IR spectrometer‚ atomic spectrometer and mass spectrometer. [2] It is being used widely in the field of physics‚ materials science

One of the leading causes of car accidents is using phones while driving. Some states have already taken action to stop this deadly problem. They enforced a law prohibiting cell phone use while driving. This solution is the best way to stop the misuse of cellphones because it allows the police to stop those who do text while driving and reduces the amount of accidents that would have occurred if the law had not been in place. Granted‚ there are some calls that cannot wait till the end of

were all specifically chosen to be right–handed and had English as their first language thus providing a fair experiment to see whether our left hemisphere (left side of the brain) or the right hemisphere is faster and more accurate. In conclusion using the mean and standard deviation to determine our hypothesis‚ it was calculated that the left hemisphere had a higher mean and standard deviation score compared to the right hemisphere. Introduction The cerebral hemispheres are very similar in

Osmosis is a particular type of passive transport involving the movement of water molecules from the region of low solute concentration to the region of high solute concentration through semi permeable membrane‚ which allows movement of solvent molecules‚ but not solute. The main principle
