pH Level Essay

Alyssa Stento Ms. Hardison Biology 30 November 2016 Pitcher This *When maintaining pitcher plants, the pH levels vary depending on the type of insect you feed it. In researching, how pitcher plants change, I found how to grow a pitcher plant, the bugs that I’m feeding it, and why the pH levels change .given these points My hope is that in writing this paper, I will be able to tell why the pH levels change in the plants because of the food its fed. Pitcher plants are carnivorous plants that are able

This report is focused on Ocean acidification and it’s lowering of seawater PH levels that results from a continuing in the amount of CO2 in the atmosphere. There are potentially adverse biological and ecological consequences occurring now and in the future results of this process. Ocean acidification refers to the increase of CO2 (carbon dioxide) within the atmosphere, which triggers a reaction which in turn increases the acidity of the ocean. Ocean acidification is caused by carbon dioxide admissions

actually affect the pH levels of water? And if so, does it make the pH level higher? Our experiment will test the hypothesis that the more polluted water is, the higher it’s pH level. We collected four samples of water from four separate locations to test its pH level based on a pollution scale we have created. On the pollution scale, 0 is clear, 1 is clear with specks of dirt, 2 is murky, 3 is a greenish tint, and 4 is brown with dirt. We will test each water sample and find it’s pH levels to conclude whether

How does the pH level of soil affects plant growth Did you know 16 million people in the world are vegetarian? Plants need soil to live, and we need plants to live. Most soils contains clay, silt, sand, stones, rocks, boulders, humus, and peat. Soil also has a pH level. “A pH is a measure of the hydrogen ion concentration of a solution.”Different climates have different soil pH. For example, soil in desert has a very basic soil pH. The pH of something can be measured using the pH scale. If it is

Slater Investigation Report on the distribution of slaters in different level of soil pH Introduction There are many different shades of grey, that slaters come in. They range from light to dark shades of grey; through when they are speckled or spotted their colours are usually green and yellow. Slaters vary in colour and pattern between individual, in the same species. Slaters in New Zealand range from 17mm in length to 2cm. Their bodies are divided into three sections: head, thorax and abdomen

different pH, or a different substrate concentration. When conducting experiments, the pH, or the substrates have to be similar because if the products are in a different area, then the results will be completely different. This is why experiments conducted have to have a similar area. The experiment conducted is about the different levels of concentration. The question is will different levels of substrate concentration and pH affect enzyme function? The hypothesis is that the pH with a higher pH will

1. At 20 seconds, pH = 7.4 2. At 40 seconds, pH = 7.4 3. At 60 seconds, pH = 7.4 4. Did the pH level of the blood change at all during normal breathing? If so, how? No, the pH level of the blood did not change during normal breathing. 5. Was the pH level always within the “normal” range for the human body? Yes, the pH level was always within the normal range for human body. 6. Did the PCO2 level change during the course of normal breathing? If so, how? No, the PCO2 level did not change during

Introduction The experimental setup will be a pH meter placed inside each water bottle of water to check the acidity in each one, and it will be tested with a pH meter. The purpose of the investigation is to see which company of water bottles has the highest pH level. The independent variables are the different companies of water, the dependent variable will be the pH level of the water, and the controlled variable will be the pH meter, the computer and wires, the glass of water, and the distilled

seconds, pH = 7.4 2. At 40 seconds, pH = 7.4 3. At 60 seconds, pH = 7.4 4. Did the pH level of the blood change at all during normal breathing? If so, how? The pH did not change during the normal breathing. 5. Was the pH level always within the “normal” range for the human body? Yes it was. 6. Did the PCO2 level change during the course of normal breathing? If so, how? No it did not change either. Activity 2a: Hyperventilation – Run 1 1. At 20 seconds, pH = 7.48 2. At 40 seconds, pH = 7

The procedure of this lab is to determine if liver and potato cells contain natural buffers that resist large change in pH as 1. NaCl or 1. NaOH are added to the solution. Hypothesis: If adding an acid or a base to liver and Potato cells then the solutions will become buffers. Materials: pH paper- cut into chunks 0.1 Molar NaCl 0.1 Molar NaOH Commercial Buffer Solution- pH 7 Liver homogenate- 10g per 100mL of water Potato homogenate-10g per 100mL of water 25 mL graduated cylinder 50mL beaker
