become extinct. Ocean acidification occurs as the ocean absorbs carbon dioxide from the air which then causes the ocean 's pH level to decrease. As the ocean 's acid levels increase, it can affect marine life by helping organisms who make energy by combining sunlight and carbon dioxide, but hurts the chemical communication, impact, and growth of many organisms by increasing the pH. Overall, the increase in carbon dioxide is bringing severe consequences to our environment and needs people who…

productivity, such as pH and substrate concentration. Every enzyme has a different “optimum pH value” (Factors Affecting Enzyme Activity). If the pH that the enzyme is working in is at this optimum pH value, it will work at its optimum speed. If not,…

tree, it can influence the growth, injury, and death of an entire forest (epa.gov, 1). Someone with little knowledge on this topic might ask, “how can rain even damage a tree so badly to point where it dies”. Well, because acidic rain has a pH of about 2 ( pH levels can be judged on a scale from 0 to 14, where 0 is considered most acidic, therefore placing acidic rain to be very acidic; comparable to lemon juice) it can break apart the protective coating on leaves which leaves them injured and…

Temperature is one of the water characteristic or more precisely one of the physical water parameters. Water temperature affects almost all other water quality parameters. It plays a key role in aquatic life and habitations. Thus, the fluctuation of temperature controls what aquatic kind will live and bloom in the water body. Water temperature can also affect “the metabolic rates and biological activity of aquatic organisms”. Therefore metabolic rates of aquatic organisms is directly…

Dianne Termine Honors Chemistry Period 5 Group: 22 Topic: Dissolving Alka-Seltzer in Different Liquids Due Date: September 30, 2016 (2) Background Research The topic of this experiment is investigating and researching whether different properties in different types of liquids affect the amount of time it takes for an Alka-Seltzer to dissolve. The independent variable would be the amount of liquid being used to dissolve the Alka-Seltzer pill. The dependent variable would be the amount of…

multiple trials with the macromolecules and test the pH levels throughout the course of the experiment. Materials and Methods The experimental design for our project was to simulate the digestion of carbohydrates, lipids, and proteins. We had set up trials for the pancreatic enzymes to break down these macromolecules and tested if macromolecule digestion had actually occurred, we also recorded the rate of their digestion by measuring pH levels. In trial 1 of our experiment we had simulated…

Benedict’s reagent detected any broken-down glucose. The same procedures were then performed waiting 5, 10, and 15 minutes before deactivating the amylase. Then again repeating the procedures with 4°C and 95°C water baths. Five test tubes were filled with pH buffers ranging from 2 to 10 in each tube before 2 mL of starch solution was added and the tubes were left to incubate at 37°C for 5 minutes. 500 μL of enzyme was added to each tube, then immediately quenched by adding 2 mL of 1 M…

was to create a clear aqueous fertilizer that had a pH range of 6.0-7.0 with first three solid compounds the first day and then four solid compounds the second day. To complete this experiment, make calculations to find how much of each compound is needed in grams, use an analytical balance to measure out compounds accurately, mix the compounds in DI water until they are dissolved, test pH levels, effectively add acids or bases depending on pH level, and administrate EDTA when a precipitate has…

usually be defined by your senses. For example, edible acids usually have a sour taste(4). Bases are more bitter-tasting and unstable(4). But, your senses are not the only ways you could detect acids. Sometimes you have to use measurements like the pH scale to detect if a substance is a acid or a base. Since, acids and bases surround us, it is important know information about them and how to detect them. Before we start measuring acid we have to know what they are. “The word acid comes from…

The human body is born with over two hundred fifty bones, as the body ages the bones fuse together into over two hundred bones. These bones can vary in structure and all have multiple functions depending on the location and purpose. Long bones may be positioned with other bones as a ball and socket, while flat bones can act as hard plates like the skull which acts as a case for the brain. Our nerves send messages throughout the body to do everyday functions such as walking, talking, and…
