Hypothesis: If four lights (UV Light, LED Light, Infrared Light, and Blue Light) are used to perform photosynthesis on a spinach leaf, then the spinach will respond most to the blue light and perform a more efficient photosynthetic process.
In the first test tube, 0.023 grams of 1-aspirin was used. In the second test tube, 0.028 grams of 2-acetaminophen was used. In the third test tube, 0.022 grams of the 3-unknown was used. In the fourth test tube, 0.028 grams of 4-caffeine was used and finally, in that last test tube, 0.031 grams of ibuprofen was used. The Unknown number for this experiment was 4.
Leah Romero 10/30/2017 Conclusion Lab 3 Chem 102L In lab 3, fundamentals of chromatography, the purpose was to examine how components of mixtures can be separated by taking advantage of different in physical properties. A huge process in this lab was paper chromatography, which was used to isolate food dyes that are found in different drink mixes. The different chromatograms of FD&C dyes were compared to identify which dyes are present in each of the mixes.
The pigments differ slightly in their chemical properties and subsequently in their relative ability to absorb light of different wavelengths. These cones are loosely called "blue", "green", and "red" as they are supposed reflect their peak sensitivities on
In science class, we did an experiment to compare inks and their compositions. This was intended for us to learn about chromatography; the separation of a mixture through a medium (the chromatography paper) in which the components move at different rates and create different patterns. We chose to explore this topic by using four different colored markers, placing a dot of each color onto one piece of chromatography paper, and observing while the water in the beaker travels up the paper and separates the dyes. Before we started, we made a hypothesis. Mine was if paper chromatography is done on the ink in the green, red, brown, and black marker, then the green will spread out into different shades of blue and green making a pointed oval shape.
Introduction Carotenoids are pigments that are found mainly in chloroplasts of plants and in some photosynthetic organisms. They are synthesised naturally in plants in order to absorb light during photosynthesis and protect plants against photosensitization. They are found in our diet, through eating fruit and vegetables and many serve as an important source of vitamin A in our diets, such as ß-carotene. The structure of the molecule determines the colour, photochemical properties, vitamin activity and its chemical reactivity on oxidising agents and free radicals.
Hypothesis: Increasing substrate concentration will increase the initial reaction rate until it stops increasing and flattens out. Independent Variable: Substrate concentration Dependent Variable: The substrate itself, 1.0% Hydrogen Peroxide How Dependent Variable will be Measured: Hydrogen Peroxide will be used in every experiment, just with different test tubes. The amount of Hydrogen Peroxide in the mixing table is the amount that will be added to each test tube.
3. Identification of Beta carotenes. Focus of this review is the identification of beta carotenes in the infrared spectrum region. In terms of metabolism and potential effects on health, beta carotene is one of the examples of most studied carotenoids. Thus the basic structure of beta carotene is made up of isoprene units.
In conclusion based off of this research for this subtopic, the property of retinotopic organization is depicts on how color is determined through the senses produced by the rods and
The Rf values of the other trials were not affected enough to change their corresponding amino acids. In order for this to be reduced, a more precise measuring device should be used. Systematic error seems to have played a large part in some of the outlying data points. For example, trial 1 of Buxus sempervirens and trials 2 and 3 of Stachys byzantina didn’t separate into any pigments. This could be due to the texture or the toughness of the leaf.
The 3 concentrations of enzymes were 0.5 ml, 1.0 ml, and 2.0 ml of turnip extract, while the substrate consisted of 0.1ml, 0.2 ml, and 0.4 ml of hydrogen peroxide. In a separate tube, the control was made up of turnip extract and guaiacol, known as the color reagent. This was recorded the absorbance every 20 seconds for 3 minutes.
Experiment #7: Column Chromatography of Food Dye Arianne Jan D. Tuozo Mr. Carlos Edward B. Santos October 12, 2015 Abstract Column chromatography is the separation of mixture’s components through a column. Before proceeding with the column chromatography itself, a proper solvent system must be chosen among the different solvents. The green colored food dye is the mixture whose components are separated.
(From Light Energy to Chemical Energy, Accessed 08 March 2018). Products to are made through photosynthesis as glucose is transported in to the plant as soluble sugars and stored as starch which is insoluble hence it is unable to escape from the cell. Although starch is able to revert back into glucose in order to release energy by respiration both useful for fats and oils for storage through the plant, proteins for growth and repair and cellulose for their cell walls. Figure 2: Structure of a leaf (FTEXPLORING, 2014), Accessed 16 March 2018) Chlorophyll is an essential need to photosynthesis as it is able to trap both blue and red light. It is a complex molecule consisting of three sub types;
This ability make the animals blend with their surroundings not only for camouflage but also for communication such as during mating. The pigment cells (chromatophores) are responsible for releasing the pigment into the outer layer of animal’s skin. The pigmented chromatophores with its variety of colors (e.g. yellow, red, orange, brown, black, blue and green) can -when used in combinations- are responsible for the numerous colors which cuttlefish can display. It is claimed that cuttlefish are the fastest color changers in the whole animal kingdom.
Fats, Soups, Sauces and Emulsions In my lab today I got to make some soup, biscuits, sauce, vanilla pudding, mayonnaise as well as oil and vinegar salad dressing. Emulsion is a process where a liquid is dispersed in another liquid with which it is usually immiscible. There are two types of emulsions. Oil-in-water (oil droplets are dispersed throughout the water) and water-in-oil (water droplets are dispersed throughout the oil).
