Column and Thin Layer Chromatography: The Separation of Spinach Pigment Abstract Spinach extract was separated into fractions containing compounds of similar polarity by column chromatography. Based on solid-liquid phase partitioning‚ this separation technique exploited the different polarity of the compounds in the spinach extract. Three fractions with different colors were obtained. The extract and its fractions were analyzed using thin layer chromatography (TLC). The TLC results showed that

Phillip had settled on a block of 1950-1960’s American television. In the file‚ original episodes of a television show called‚ Leave it to Beaver‚ were sectioned off in blocks by season. That show was at the top of the list along with one called‚ Gun Smoke‚ and a prehistoric cartoon called‚ The Flintstones. But‚ Phillip’s favorite record in the entire file was one of a man called

In House of Leaves by Mark Danielewski it discusses the experiences everyone endures once entering the house‚ although the people that enter the house are primarily males as the reader I become part of the book. Resembling to the characters we all symbolize something different‚ however by the end the characters all become interconnected by causing some harm to themselves or become insane because they cannot determine what is occurring in the house. However‚ I have learned to not be afraid of the

rate of photosynthesis. Prediction I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion‚ so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. There for the rate of photosynthesis will decrease proportionally with the distance of the light from the plant (in this case a half). This means that as the light moves away then there is less light given to the reaction for photosynthesis to happen

water on the rate of photosynthesis. Aim: The aim is to investigate how increasing carbonate in water can affect the rate of photosynthesis. Introduction: The rate of photosynthesis can be increased or decreased in many different ways. For example‚ by adding substances like alkaline or salt to the water‚ you can increase or decrease the acidity or basics‚ if the water has too much acidity‚ it can often delay the rate of photosynthesis‚ often stopping the rate of photosynthesis in the plant‚ which

The labia (lips) protect its anterior opening‚ the cheeks form its lateral walls‚ the hard palate forms its anterior roof‚ and the soft palate forms its posterior roof.

I would like to start by explaining what this essay is not. This essay is not a whimsical attempt at justifying the academic study of religion by suggesting it is of higher moral worth to do so. I have no interest in saying that just because religion has no practical application‚ that should not stop me from studying it for my own interest. I will not try to spin the communication‚ writing or critical thinking skills that come with religious study‚ into generic qualifications that will open the world

The effect of different coloured lights on the rate of Photosynthesis Objective: To find out which colour of light provides the best consequences for the production of oxygen/ the rate of photosynthesis Background: In photosynthesis‚ there are two main parts‚ including light dependent and light-independent reactions. Plants use the energy from light for producing sugar‚ which is being converted into ATP by cellular respiration. They also are the only organisms that produce oxygen along with glucose

AFFECTING THE RATE OF PHOTOSYNTHESIS. Introduction Photosynthesis is a chemical reaction which takes place inside the green plants (plants with chlorophyll‚ a pigment found in chloroplasts which causes the colour of the plants and it is the main photosynthetic pigment) and light energy is converted into chemical energy. Carbon dioxide‚ water and sunlight is transformed into sugar an oxygen‚ which later will be used as energy for the plant. The chemical equation of photosynthesis is: Photosynthesis

The central message of this advertisement is if you want to be strong like Popeye‚ eat their spinach. I can recall waking up Saturday morning watching the cartoon Popeye as a child. Popeye was always trying to impress Olive Oil. Popeye wasn’t the only one with eyes for Olive Oil‚ his nemesis‚ Pluto also had a very hostile interest towards Olive Oil as well. The cartoon would start out with Popeye planning something nice for Olive Oil‚ the day would be going perfectly. Pluto would notice Olive
