For this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution.
• The honeybee detects ultraviolet light patterns on flowers via the photoreceptors in their eyes, allowing them to distinguish between those with pollen/nectar and those without. • The Japanese Dace Fish is able to detect UV light, assisting in mate selection and detection of prey- hence helping survival as prey is able to be
In the lab “All That Glitters” the objective that was focused on during the lab was calculating the density, volume and mass of various substances. The method that was used in finding the volume of the samples is called the displacement method. This is a process where the volume of the water in the graduated cylinder is calculated before and after the sample is placed. In this lab, the goal of the experiment was to identify and come to consensus about what the unknown substance might be. For this experiment, the required materials were ten pre and post pennies, unknown sample, graduated cylinder, weigh boat, water, paper towels and a weighing scale.
The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.
After putting my organisms in an environment, the organisms with the color that best blended with the environment’s color would increase in numbers. Whereas, organisms with a dissimilar or opposite color to the environment would die-off over time. The reason why organisms that could better blend in with the environment flourished, while the organisms who stood out in the environment died is because of natural selection. The organism that could better blend in would be harder for predators to find, thus increasing its chances of living and reproducing. While the organisms that stood out would have a higher chance of being eaten or
Then each Skittlefish had one offspring of the same color. By the end of five years, only the orange Skittlefish had survived and reproduced, and it was clear how the genetic diversity had lessened over the span of those five years. The graphs show that the orange Skittlefish would always be the least impacted by predators compared to the other colors, showing that the population in its entirety, not just the individual, was impacted by the environmental factor of
A. 0.4 The gray allele is f, which represents q, but the frequency is q2 which is: 16/100= 0.16 The square root of q2 (0.16) equals 0.4. the frequency of f, a.k.a 'q' is 0.4 B. 0.6
“From Blue to Red” 1 in 10,000 crawfish are blue. It can happen as a result of a mutation in the gene responsible for pigment formation. They stand out from the rest of the crawfish due to their obvious differences. Isolation can relate to a blue crawfish as it makes people feel lonely and as if no one can relate to them leading to a loss of hope and joy. The best treatment, however, comes not from medications, but happiness which can be found in times as simple as conversations with family.
Conclusion The question investigated was if baking powder, cornstarch, or flour will affect the rate of fermentation. The hypothesis being tested was that all the ingredients will have around the same rate of fermentation because they all contain 0-0.3 grams of sugar. The hypothesis is rejected. This is because after twelve minutes, baking powder had 2.2 centimeters of bubbles, cornstarch had 2.1 centimeters of bubbles, flour has 1.3 cm of bubbles, and the control had 0.5 centimeters of bubbles.
In order to grasp to what extent we can reliably interpret the animal colour from the fossil record, first it must be established how such colour is generated, with an understanding of the taphonomic processes resulting in its preservation consequently being equally crucial. When examining extant species, the mechanisms through which colours are produced can be roughly split into two categories; colours produced through pigmentation, and those produced through structural means, with considerable overlap occurring between the two. Pigmentation is achieved through the absorption of particular wavelengths of visible light (the wavelengths visible light being between 380 and 750nm) by chromophores, regions of organic molecules responsible for colour. The wavelengths that are not absorbed by chromophores are consequently reflected, resulting in the distinctive colour of the pigment. Containing either metal complexes or conjugated π-bonds, chromophores comprise vacant electron orbitals, which are filled when electrons are excited from their ground-state.
Human color vision is broken down into 3 pigment sequencing of genomic and DNA clones that encode the apoproteins of these 3 pigments the; deduced amino acid show 41 +/- percent identity w/ rhodopsin. Red and Green 96% mutual but only 45% with blue. Green varies among color-normal individuals and together w/ a single red pigment gene, is proposed to reside in a head-to-tail down array with the X chromosome. Absorption spectra of cone photo pigments over the spectral range of 530 to 562 nm are a principal cause of individual differences in color vision within and across other primates. Nucleotide sequences were determined for 8 primate photo pigment cones.
“In 1775, more than a million pounds of indigo was exported from South Carolina to England” (Indigo’s Political, Economic, Cultural History 1). This massive amount of dye being traded was due to many factors that made it nearly the perfect trade commodity. The process of indigo dye being made by slaves in South Carolina in the 1700s is shown very well in the book Someone Knows My Name by Lawrence Hill. The production of this indigo dye has an extensive history of being extremely arduous to produce naturally, but results in a compact substance that will last a long period of time and be very valuable.
A dye is a coloured substance that has an affinity, a bond with a physical surface, to the substrate to which it is being applied. Dyes are usually soluble in water. Dyes are used to change the perceived colour of an object. Dyes consist of 2 main parts: chromohore and auxochrome. Before 1856, all dyes were obtained from natural resources.
It's so crazy because how do they know what color to be if they are color blind. Another cool fact about the cuttlefish is that with their amazing pupil, they can also see behind themselves. This helps tremendously with protection and
“When I was 12 years old I was going to science we were doing our safety lab so we were going to all the stuff she showed us the fire extinguisher and It went off and hit the table, it then went in my eye I think I was shocked that it went off I jumped up and ran back and forth I was freaking out, then my teacher got me and ran me to the eye washer and I walk back and was trying to help clean the mess, but my eye burned bad so I went to the clinic so they washed my eye out and told me to take off my shirt and she gave another one She called my dad to let me talk to him my eye was all red. I think my teacher thought that the pain was till I the think when she thought It was was saved to pick it up and pick it up
