Marcelo Duka G-7L BIO 2 RESPIRATORY SYSTEM The Respiratory system consists of organs and tissues that aid the oxygen to travel in the body and emits the waste gases out of the body. It is also called as the oxygen delivery system for it is the system responsible in delivering the oxygen to all parts of the body. The process of breathing‚ the inhalation of oxygen and exhalation of carbon dioxide‚ is called respiration. Respiration can be described into two processes: internal or cellular

THE 4 QUALITIES OF GOOD WATER by Dr. Robert O. Young There are many measurements of water‚ but the most important for determining the best water to drink are‚ the pH‚ oxidative reduction potential—or energy potential/activity—molecular structure‚ and purity. Science has helped us to determine that the best measurements for our drinking water are the pH and purity‚ but little understood is the importance of the molecular structure of water. Assuming that most waters that humans are drinking

of pure and excess nitric acid‚ it can decompose to nitrogen dioxide and chlorine: elevated temperature 658 NITROSYL CHLORIDE 2ClNO + HNO3 → 6NO2 + Cl2 +2H2O Also‚ nitrosyl chloride can be synthesized from its elements by heating nitrogen‚ oxygen and chlorine gas at 400°C: N2 + O2 + Cl2 → 2ClNO Faraday obtained nitrosyl chloride by dissolving palladium in a mixture of hydrochloric and nitric acids (Faraday‚ M. Trans. Roy. Soc. (London)‚ Vol. 136‚ pp. 48‚ 1846): Pd + HNO3 + 3HCl → PdCl2 + ClNO

and 4‚ I believe the algae accumulation in the lake is the cause of the dead fish. It could be because the algae are using up vital oxygen sources that the fish need to survive. Table A on page 3 shows the amount of dead fish increase as the number of algae cells increase. This shows that the algae and fish are competing for oxygen‚ and the fish are losing. Also‚ oxygen levels in the lake slowly decreased over a 3 day period‚ as shown by Table B on page 3. This possible algae-fish competition might

is important for life because the fresh air from the chlorophyll is doing photosynthesis. Plants also make food and oxygen. Then plants is doing photosynthesis‚ it must have sunlight to make their own food and oxygen. The equation about photosynthesis basically is CO2 + H2O C6H12O6 + O2 ( means need the chlorophyll and sunlight). Photosynthesis can make their own food and also oxygen for Earth as well‚ so photosynthesis is absolutely important for life. Inside the plant‚ it has a power house called

waves crash about‚ air is mixed with the water‚ thus increasing oxygen content. This is due to the fact that when waves crash about‚ the water will be more exposed to the air and cause an increase in the amount of oxygen present in the water. When the tide is low and periwinkles are exposed‚ there is no shortage of oxygen for the periwinkle snails either because the surrounding air is composed of around 21% oxygen‚ which is enough oxygen for a periwinkle snail. To survive in conditions that change

food molecules are oxidized to synthesize ATP used to drive the metabolic reactions necessary to maintain the organism’s physical integrity and to support all its activities. This is achieved by either aerobic (in the presence of oxygen) or anaerobic (in the absence of oxygen) respiration. Aerobic respiration is a more efficient process as up to 30% of the energy in glucose makes its way to ATP whereas only about 2% of the energy available in glucose is usable by the cell through anaerobic respiration

The Decomposition of Potassium Chlorate Hypothesis: Potassium chlorate decomposes into potassium chloride and oxygen gas‚ which means that when the glowing splint is inserted into the test tube‚ the flame will have enough fuel to fully reignite the splint. When the manganese dioxide is added‚ this will increase the rate of the production of oxygen in the reaction‚ without affecting the state of the manganese oxide.

environments affect the reactivity of catalase? Hypothesis- If more catalase is added then more oxygen (kPa) will be produced in a faster rate because there is more catalase to react upon. If less catalase is added then less oxygen (kPa) will be produced in a slower rate because there is less catalase to react upon.

energy is created by making carbohydrates from carbon dioxide and water in the presence of chlorophyll. Plants release large amounts of oxygen into the atmosphere as they produce much more than needed during the photosynthesis process. Aerobic respiration is an important process in life as we know it. This process further breaks down molecules and sugars using oxygen. During this process adenosine triphosphate (ATP) is created‚ used to store and transfer energy to cells throughout the body.
