interaction between the two layers. The reason why there is a difference in the density of the same body of water‚ is due to the dissolved oxygen (DO) intake of water. With cooler water having a greater capacity to hold oxygen compared to warmer bodies of water. Usually this problem is fixed with the combination of photosynthesis from plants that produces oxygen‚ and wave to wind action that help breaks down thermal stratification and allow for water on the surface of the pond to be oxygenated by

placed within the cylinder. To control the amount of energy that would be entering the system‚ we placed all three cylinders under a light with a timer. The timer would allow the light to turn off for a set amount of time‚ thus mimicking a day/night cycle within the system. Each class was then given the responsibility of recording their observations during the first few minutes of class at the beginning of the week. Discussion and Anaylsis: From what can be seen through the data it is certainly

6O2 ⇒ 6CO2 + 6H2O + ATP. Glucose is broken down into 2 pyruvate. The pyruvate then travels through the Kreb cycle and produces carbon dioxide. The oxygen travel through the electron transport train and produces water and energy. In order for the body to maintain homeostasis while exercising more oxygen is needed and cellular respiration increases. In return for a greater intake of oxygen‚ more carbon dioxide is produced and exhaled‚ therefore changing the color of the the bromothymol quicker. The

and carbon dioxide to to create energy sugar ‚and oxygen. Photosynthesis also absorbs molecules that are called pigments. The process of photosynthesis is used by plants to make food for themselves. By then doing this‚ it also benefits us humans and animals by releasing carbon dioxide. Oxygen to them is considered a waste product‚ but a necessity to us. The photosynthesis process is a very important and critical part of nature and keeps the cycle of life running. First‚ the plants need energy

cellular respiration and what are its three stages? Cellular respiration is the aerobic harvesting of energy from food molecules. The first stage of cellular respiration is Glycolysis. The second stage of cellular respiration is the citric acid cycle. Lastly‚ the third stage of cellular respiration is the electron transport. • What is the role of glycolysis? Include the reactants and the products. Where does it occur? The role of glycolysis is to split the sugars. During this process

energy. o During the light-dependent reactions‚ solar energy is absorbed by chloroplasts (see B-2.2) and two energy storing molecules (ATP and NADPH) are produced. o The solar energy is used to split water molecules which results in the release of oxygen as a waste product‚ an essential step in the process of photosynthesis. The second stage is called the dark (light-independent) reactions because they do not require solar energy. o During the dark (light-independent) reactions‚ energy stored

These are the steps of the cycle: 1. Carbon enters the atmosphere as carbon dioxide from respiration and combustion. 2. Carbon dioxide is absorbed by producers to make carbohydrates

process. In the first week it turned brown and we believe‚ soapy. So we hanged it out and started fresh. In the beginning‚ it was always murky with low oxygen. We believe it is because our plant life was unhealthy and dying. So‚ therefore‚ it was not performing photosynthesis. We added new plant life and the water became clearer and the oxygen level started to gradually rise. The last week of the project‚ the water started to become cloudy again because the plants were dying. We think all of
