Oxygen

Composting). Oxygen is needed for microbes to try to decompose waste efficiently; it wont stink as bad in the end if the area is kept well aerated (Chapter 1, The Decomposition Process). If oxygen levels are lower than 5 percent, it will cause the pile to go anaerobic, meaning it will get smelly and gross (Chapter 1, The Decomposition Process). If there is a change in temperature the aerobic bacteria could end up dying (The Science of Composting). Due to changes in moisture, oxygen, and acidity…

Exercise's Effects on Cellular Respiration Cellular respiration is a chemical reaction that creates energy through your cells. It requires inhaled oxygen and expels carbon dioxide. This carbon dioxide can be detected through the use of bromothymol blue (BTB), which is a pH indicator solution. When the carbon dioxide is exhaled into the solution, BTB reacts as it would with any other acid, and turns from blue to yellow. The higher the level of carbon dioxide, the more quickly the color changes…

the normal amounts, and discuss what each represents. Arteriole Blood Gases is "the sampling of the blood levels of oxygen and carbon dioxide within the arteries, as opposed to the levels of oxygen and carbon dioxide in venous blood." 1. pH: (7.35-7.45) measurement of acidity or alkalinity based on H+ ions present in the blood. 2. pO2: (80-100 mm hg) the partial pressure of oxygen that is dissolved in the arterial blood 3. HCO3: (21-28 mEq/L) this is the calculated value of the amount of…

rocket. The ethanol is also ‘absorbed’ by the fire of the match. If the bottle was larger, it was covered in more ethanol and had more oxygen in it, which would create a larger reaction and produce more energy. When ethanol and oxygen are reacted it is called a combustion the chemical equation is C2H5OH + 3O3 = 2CO2 + 3H2O. This tells me that when the ethanol and oxygen reacted, carbon dioxide and water…

decomposition of hydrogen peroxide to form water and oxygen, which occurs spontaneously, but not at a very rapid rate. Write a balanced equation for this reaction. Label the reactant and the product. (Remember that catalase is not a reactant or a product and can be written over the arrow separating the reactant from the products.) I will help you with the equation. Catalase 2H2O2 ------------------------> 2H2O + O2 (g) (Hydrogen peroxide) (Water) (Oxygen) 2. Explain why, in your first…

exercise. This is because the muscles will need more oxygen to work at their optimum level. The typical resting heart rate is from 60 – 80 beats per minute therefore the pre exercise heart rate will usually rise above this preparing the body for the activity. The heart rate will continue to rise till you have held a constant intensity once you have reached this your heart rate will begin to plateau, because the muscles don’t need any more oxygen…

BACKGROUND Photosynthesis is a solar-powered process that transforms energy from the sun into oxygen and carbohydrates (Harris-Haller). For the process to occur visible light, water and carbon dioxide have to be present. When photosynthesis has occurred the final product includes organic molecules such as glucose an oxygen (necessary for cellular respiration). There is a significant correlation between photosynthesis and cellular respiration. During photosynthesis, the plant uses carbon dioxide…

Riley 1 Why is Evolution so important? Some might ask this because of the confusion drawn over the topic. However it is one of the most intriguing scientific theories that exists today. Evolution is far more interesting than the Theory of Gravity, or Germ Theory. This one addressed many age old questions, such as what is our place in this world, and where did we come from. Some might not accept it because it may conflict with their religion, especially in America, where only 60% of all Americans…

Salts and molecules have similar characteristics, and many differences whether we can tell by first looks or not. Testing these two only supports the differences, and many structural functions cause these differences. Since salts are ionically bonded, they have different properties and functions compared to the covalent bonded molecules. Salts have a ionic bond, and we can confirm due to their electronegativity. As you move from left to right on the periodic table you would notice that…

completed then the Calvin cycle begins and that’s when the carbons are rearranged several times to then create glucose. Carbon Dioxide is catalyzed by RUBISCO through photosynthesis. Once this occurs several ATP is then created and stored for energy. Then oxygen is released from photosynthesis as well. If a green plant is exposed to only green light in a laboratory, predict what will happen to the green plant. Why? - So, green plants are not actually green they reflect the green color. When…
