abundant chemical element in the universe. It forms 1- ions when combined with metals‚ and 1+ ion when combined with non-metals to form acids. Hydrogen is “the fuel of life”; without it to combine with oxygen we would not have water. Water is made of two parts hydrogen and one part oxygen. Oxygen burns hydrogen in the living system‚ releasing energy that runs our bodies. Hydrogen Peroxide keeps teeth and gums healthy preventing Gingivitis (gum disease). Carbohydrates like sugar‚ pasta and bread

welding is a process that use fuel gases and oxygen to weld and cut metals. Uses: 1-welding and cutting metals 2-in Stone Work for flaming 3-in the glass industry for fire polishing 4-in jewelry production How we use it : The apparatus used in gas welding consists basically of an oxygen source and a fuel gas source it’s pumped through hoses and get out to cut or weld the used metal and there are two cylinders one of them contain oxygen and we can control the amount of gas used

Introduction: Air goes into the alveoli when we breathe in. This lets the veins around the alveoli drop of their carbon dioxide and pick up oxygen. The oxygenated blood travels around the body and drops of oxygen to cells and picks up carbon dioxide. It travels back through the veins through to the heart and then to the lungs again and repeats the progress. Cells use oxygen and produce carbon dioxide when being more active. The subjects were moving to make their cells become more active. The reason for

To learn the skills of inoculation agar tubes and agar plates. Introduction Microorganisms are able to carry out different biochemical activities with the ease of different enzymes. Each of these enzymes carries out one specific type of the chemical transformation. They convert substrates into product. A) Carbohydrates Fermentation Microorganisms utilize

breaks it down into smaller molecules that can be absorbed into the bloodstream. Cells can then use the molecules for their maintenance. The respiratory system takes in oxygen from the atmosphere and then passes it into the bloodstream in order for it to be delivered to all the cells in the body. The circulatory system delivers the oxygen to all the cells but is also picks up the carbon dioxide and waste from the cells. The carbon dioxide is taken back to the lungs. The carbon dioxide is diffused from

nearby soil in its roots. The leaves then take light energy from the Sun‚ which is absorbed in the chlorophyll in the cells and passes it along for it to be used in photosynthesis. Glucose is produced and is converted into Starch to be stored. Oxygen is produced from the water and it is a waste product so it is released into the air. The plant uses Carbon Dioxide and water to create Carbohydrates.

COPD COPD is characterized by airflow limitation that is poorly reversible. Cumulative‚ chronic exposure to cigarette smoking is the number one cause of the disease‚ but repeated exposure to secondhand smoke‚ air pollution and occupational exposure (to coal‚ cotton‚ grain) are also important risk factors. Chronic inflammation plays a major role in COPD pathophysiology. Smoking and other airway irritants cause neutrophils‚ T-lymphocytes‚ and other inflammatory
