reverse of each other. In photosynthesis, carbon dioxide and water work together with the protein complexes present in the chloroplast and with the aid of the energy coming from the sun to yield glucose and oxygen. Meanwhile, in cellular respiration, glucose is broken down with the aid of oxygen and enzymes present in the mitochondria into carbon dioxide and water, which are the starters of photosynthesis, and produces energy in the form of ATP. The light independent (LI) reactions of…

The lack of oxygen in the water, or hypoxia, endangers the fish which will fight for survival or die. The lack of oxygen creates a "dead zone." One of these dead zones exists right off the coast of Myrtle Beach. Pollution also affects life around the water. If an animal drinks water from a polluted pond, it can get…

dopaquinone is converted to melanin in the hair follicles, skin and the retina. Tyrosinase is also responsible for the brown color that forms on the inside of fruits and vegetables after they have been cut. The tyrosinase catalyzes the reaction with oxygen and catechol. Catechol is an organic alcohol found in most plants. Tyrosinase and catechol oxidases have a binuclear type 3-cooper center.…

on the coin, and was put on the coin in 1909 (pennies.org). The penny was the first U.S. Cent to include the words “in God we trust” (pennies.org). Now how do they become dull and dingy? Pennies become dirty because their copper. The copper and oxygen mixes to form copper oxide. Copper oxide is also known as cuprous oxide. Cuprous oxide occurs naturally in some parts of the world as cuprite (wisegeek.org). Cuprite is used in many other substance such as glucose and some types of sugars.…

The purpose of this investigation was to find a high regression rate fuel suitable for use as a mixture with hydroxyl-terminated polybutadi- ene (HTPB). Guanidinium azo-tetrazolate (GAT) is the compound that was the focus of our re- search. GAT is a salt containing a high per- centage of nitrogen. It has two conjugated ni- trogen rings, which are negatively charged, and a positively charged component consisting of nitrogen, carbon, and hydrogen. In addition to the high-energy content of this…

8)Thermoregulation is the process your body goes through to keep your body's temperature regulated to 60-38°C. 9)The hypothalamus is the portion of the brain that monitors and regulates the body's temperature. 10a)The body will expand blood flow in the skin and have the sweat glands produce more sweat. 10b)The body will restrict blood flow in the skin and have muscles shiver to generate and keep heat. 11a)The stimulus is the hypothalamus sensing to little heat in the body and the response is…

converted into energy of organic molecules. This process is responsible for present life on Earth because it provides food for all living things. Photosynthesis is only found in certain photosynthetic organisms; a few bacteria and plants. Plants produce oxygen as a “waste product” when they produce energy using light energy, water, and CO2. The equation for photosynthesis is “CO2+H2O+Energy--> (CH2O)n+O2, however, if this equation was read right to left, it would be respiration. Respiration…

various system of the body get acclimatized to enable a person to live at high altitude Changes in Blood RBC count increases and packed cell volume rises from normal value of 45% to 59%. Hemoglobin content in the blood rises from 15 to 20%g. so the oxygen capacity of the blood increases. Increase in RBC count, packed cell volume and hemoglobin content is due to erythropoietin that is release from juxtaglomerular apparatus of kidney. Changes in Cardiovascular System In high altitude, the…

but only ⅓ of your lung capacity is used during normal activity, but this fraction increases during strenuous activity when the body requires more oxygen such as jogging, playing sports, etc. On average males have a 20-25% higher lung capacity than females and taller individuals rather than smaller people. Respiration is the exchange between oxygen and carbon dioxide (wisegeek.org,…

fertilizer company). But, you need it to grow the crops. The land is arid and dry without it, and trying to grow things is likely to be futile.” - Shellen Lubin. According to a paper written in Science, the ocean has lost roughly 77 billion tons of oxygen in the last 50 years, being up to nearly 2% of its waters (USA today). Algal blooms have been a straining issue, causing wildlife and oceans to perish under it’s suffocating mass; these are created by surplus of nutrients, many that have been…
