The Effects Of Pollution On A Natural Environment

Pollution is one of the biggest global killers, affecting nearly 100 million people. Pollution comes in many different forms and affects the world and the environment in many different ways. Along with the best known pollutants such as water, air, and land, there are other pollutants that many people do not know much about. These include light, noise, thermal, and household pollution and are all just as damaging as the most known ones. Pollution is an introduction of a harmful or poisonous substance into the environment that has a negative effect on life around it. Pollution is deadly, and it is destroying the only world suitable for life. Pollution is a

In the experiment we used Turnip, Hydrogen Peroxide, Distilled Water, and Guaiacol as my substances. On the first activity, Effect of Enzyme concentration of Reaction Rate for low enzyme concentration, we tested three concentrations of the turnip extract, and hydrogen peroxide. For the Turnip Extract I used 0.5 ml, 1.0 ml, and 2.0 ml. For hydrogen peroxide we used 0.1 ml, 0.2 ml, and 0.4 ml. We used a control to see the standard, and used a control for each enzyme concentration used. The control contains turnip extract and the color reagent, Guaiacol. We prepared my substrate tubes separately from the enzyme tubes. My substrate tube

pollution - the process of making land, water, air or other parts of the environment dirty and unsafe to use.

Pollution is defined as the process of harmful substances being released into the air. Some of these substances include Carbon Monoxide, Sulphur dioxide, Lead and PM2.5. PM2.5 is small particles which are smaller than 25 thousandths of a millimeter. This polluted air will fill your lungs with tiny particles and cause Lung cancer, Asthma and other heart and lung diseases.

Then we inverted the tubes so an air bubble would form in the little tube that is now upside-down. Now that we know what to do, we marked the little tube 2/3 full. One tube was filled to that line with glucose solution, another with fructose solution, sucrose solution and the last one with water. Next, the little tubes were topped off with a yeast solution. Then we slide a big tube over the little one and completed the inversion, this is done for every little test tube. After they are all inverted our group measured the bubble present at the top of the little tube. Then we put all of the inverted test tubes into a hot water bath for 20 minutes. After 20 minutes we took the tubes out and measure the air bubbles in the tubes. Next, we recorded the data calculated the net change from the beginning of the experiment to after the hot

The results of the mean of the concentrations are as followed; 0%, 0.2%, 2.0% and 1.0% which are in organization of longest float time to shortest. The higher the concentration of sodium bicarbonate (carbon source) the quicker the process of photosynthesis occurs. The mean of the concentrations is; 0% is 900, 0.20% is 757.58, 1.0% is 580.004 and 2.0% is 582.54. The standard deviations of the concentrations are; 0% is 0, 0.20% is 190.0045, 1.0% is 247.9306 and 2.0% is 199.979.

Based on the reactions in each test tube , we

What is pollution? It is the introduction of a contaminant into a natural environment, usually by humans. Most of us think of pollution as chemical waste being dumped into rivers or factories spewing toxins into the air. Pollution can be as simple as throwing your trash in a river or leaving it on the riverbank. This trash often causes problems for our wildlife in and around the river.

In first half of the experiment, we tested 5 different compounds which one could work as an inhibitor. When using a 5-ml pipette with a green pump, we placed 5 ml of distilled water in each small labeled test tube. After that, we went to place 8 drops of potato extract, 8 drops of catechol, drops of an inhibitor, and then drops of distilled water. The only concentration that we had alternated in the experiment would be the drops of catechol and drops of distilled water. In tube 1, we placed 8 drops of catechol with 8 drops of distilled water in the tube, containing NO potato extract. In tube 2, we placed 8 drops of catechol, NO distilled water, and 8 drops of potato extract. In tube 3, we placed NO drops of catechol, 8 drops of

Higher levels of solution should produce higher levels of product. The independent variable for the control group data and the experiment data is the yeast concentration. The dependent variable for the control group data and the experiment data is how much oxygen is produced. The Constant for the control group data and the experiment data is time and amount of hydrogen peroxide. The products of the experiment will increase if the levels of reactants increase. Denatured yeast may cause change in the reaction of the experiment. For all trials of the control group, the concentration of yeast is 6ml. For the experiment data, the yeast concentration varies from 8mL, 10 mL, 12 mL, 14 mL, and 16 mL. The temperature may cause change in the reaction of the combination of yeast and hydrogen peroxide

The independent variable is the amount of dissolved oxygen in water measured in percentage. – In order to obtain a more accurate value of dissolved oxygen I will measure it in two different ways. I will measure it by using an oxygen-selective electrode

The first portion of the lab was about preparing the standard curve for the reaction products. In this part we already know the concentration of the product, Nitrophenol. So, to perform this we took six test-tubes and filled each with 1ml of standard labeled with S1-S6 respectively. For example 1st =S1, 2nd=S2, 3rd =S3 and so on. After that we measured the absorbance of each test tubes setting the first one as blank. And the data is recorded in the table (5.1). After recording the reading we constructed a Nitrophenol Standard curve by plotting A410 on y-axis and concentration on the x-axis as on figure (5.2). The second portion require us to prepare acid phosphatase from the wheat germ extract. But, this part of the lab was already

Pollution is caused by people littering, throwing their trash everywhere, wasting energy, and burning fuel from vehicles. Pollution effects all animals and plants from around the world. It can harm them and kill them. Some animals have gone extinct because of pollution, thanks to humans. To be exact, over 11 species of animals have gone extinct because of pollution, Not to mention people have died too! How much? Well, about 6.5 million people have mainly because of respiratory problems (lung cancer caused by air pollution) . Yea, its really bad. Pollution has been around for a long time in the U.S since the mid-19 centuries. It got worse because of the industrial revolution. This caused the air and water to become polluted because of all of the manufacturing factories, which uses coal for their factories and threw their waste

All group members began by setting up the lab by obtaining all required materials and placing them on the lab bench. A buret was then rinsed twice with water and once with HCl(aq). It was then filled with 30 mL of the titrant, HCl(aq). The pipet was rinsed twice with water and once with Ca(OH)2(aq) . The pipet was filled with 10 mL of Ca(OH)2(aq) and then emptied into a flask. 20 mL of water and three drops of indicator was added to the flask containing Ca(OH)2(aq). The flask was then placed under the tip of the buret. The stopcock was rotated which allowed the addition of small amounts of titrant into the flask containing calcium hydroxide solution with bromothymol blue indicator which has a light blue appearance. In each trial, the base was titrated to the endpoint; the endpoint was where the solution in the flask changed colour from light blue to yellow. The buret readings were recorded before and after the titration was completed. Finally, the titration was repeated two more times, resulting in obtained data for all three trials. After the lab was performed, all equipments were washed and dried well by

During the Benedict's test, the contents of tube B did not change, indicating the absence of sugar in that particular substance. However, the contents of tube A did change orange indicating the presence of sugar in that substance. During the Lugol's test, the content of tube A did not change dark purple indicating the absence of starch in that substance However, the content of tube B changed to dark purple
