What Happens When You Put The Grinding Green Peas Into The Colorimeter

424 Words2 Pages

Variables (Independent, dependent, control, uncontrolled) (discuss) Likely impact upon the investigation How the variable will be changed/ measured/controlled Independent variable The temperatures [ 20℃ (control), 30℃, 40℃, 50℃, 60℃, and 70℃] Heating the green peas may allow the texture or color of increase in the colorimeter. The variety of temperatures will give us a view of the effectiveness on the green pease color. Dependent variable Colorimeter Colorimeter measures the amount of light transmitted through a wavelength. You put the grinded green peas into the colorimeter. The colorimeter measures the absorbance. Experimental Control: Colorimeter at 20℃ This variable will show us to what extent will the value’s differ …show more content…

Which can change the texture and appeal for the green peas. The amount of peas grinded and poured into colorimeter can have a certain effect on the value of the calorimeter. It will debunked the data and not prove the hypothesis. In the colorimeter we have the ability to control the amounts of wavelengths. Keeping it at different wavelengths will not only change the data’s value be able to assess the data if not using the same wavelengths. Water has a high specific heat capacity. Keeping it at the same amount for peas can allow us to hold in consistent amounts of heat to be able to get the right data. If the cover is not closed during process of finding the absorbance of the colorimeter, there will be light entering into the solution which can alter the data. Use a thermometer and affectively watch the temperature rising and decreasing. Asses the situation and effectively collect data. Pour in the same amount of peas for every trial. This will give us the reliable data on how temperature can affect the color of the peas not the concentration. Altering the wavelength capacity can change the data. Maintaining the wavelength not only keeps consistent data but allow us to analyze it for accurate

Then five millilitres of sample “A” were placed in the test tube labeled “A”. This was then repeated with the next three samples. Each sample was visually observed and the colour of each was recorded. Next 20 drops of Benedict’s solution were added to each test tube and the test tubes were lowered into a hot bath at a temperature of approximately 80 degrees Celsius. All colour changes were recorded.

How did different colors of light affect c02 consumption in spinach leaves? Background Photosynthesis is a process by which plants and other autotrophs make their own food using sunlight energy. Plants take in water, carbon dioxide, and use sunlight energy to create glucose and oxygen. Plants use the glucose as energy and release the oxygen as a by-product.

Especially since the experiment states that it was a healthy plant, whereas a yellowish, drooping malnourished plant would not be able to provide sufficient data. So for the time being it'll take in CO2 until it stops functioning without the sun. Tube C would also be yellow because there is no longer equilibrium once the plant runs out of initial energy from it's previous lit environment(before being used for the experiment). Tube D will not change because there is nothing with get the blue

Amylase Lab Report

During the biology lab, we did a various experiment to examine the hypothesis that there is a positive correlation between ancestral starch consumption and amylase gene copy numbers. These experiments were done to answer the research question: Is there an association between enzyme production, gene copy number, and gene evolution?!We did our experiments on the specific enzyme called Amylase which is responsible for hydrolyzing amylose to its monomers. At the very beginning of creating the calibration curve with measuring the absorbance of different standard amylase concentration, is critical to consider that the absorbance is proportional to the intensity of colour and the concentration of the solution.(Tracey 2017)meaning that when the colour of

The cones that respond to the maximal sensitivity in the long wavelength light respond to orange-red color, cones that respond to the maximal sensitivity in a middle wavelength light respond to yellow-green color and cones that respond to the maximal sensitivity in the short wavelength light respond to blue color. Other colors could be sense through the combination of the three types color. Example, the formation of yellow with the combination of red and green color, formation of magenta with the combination of red and blue color, formation of cyan with the combination of blue and green color and formation of whiteness

The starch-iodide complex forms because of the transfer of charge between the starch and iodide ion and results in spacing between the energy levels. This allows the complex to absorb light at different wavelengths resulting in a dark blue colour (Travers et al., 2002). A blue colour would indicate a positive test while a yellow colour would show a negative test. The Benedict’s test is useful for reducing sugars.

Germinated Peas Inspire Synthesis

The purpose of this lab was to measure the amount of CO2 gas given off by germinated peas under certain conditions of light. We conjectured that the more amount of light the peas are exposed to, the higher the respiration rate they will have. Our data supported this because it showed that the germinated peas that were exposed to light 24 hours before the experiment had a steeper slope (as seen in table 1), therefore having a greater respiration rate. The peas that were not exposed to any light 24 hours before the experiment had a reduced rate because of its lack of exposure to light. Both pea’s respiration rates showed that the more light the peas were exposed to, the greater respiration rate they would have (Figure 1).

With the use of colorimeter, it will show how much light can be transmitted through the solutions. When the cells in the solution are centrifuged, they go to the bottom of the tube to form pallets. The liquid above the pallet are clear then they are able to quickly transmit light. However if the cells has erupted, the hemoglobin is released will be left above the pallet and observed cloudy. This will cause the solution to have less light transmitted during the use of
