this article‚ we’ll see how these parts come together to produce bright light for hours on end. Light Basics Light is a form of energy that can be released by an atom. It is made up of many small particle-like packets that have energy and momentum but no mass. These particles‚ called light photons‚ are the most basic units of light. (For more information‚ see How Light Works.) Atoms release light photons when their electrons become excited. If you’ve read How Atoms Work‚ then you know that electrons

Individual plants and animals could not exist by its self on earth. All organisms need other organisms for survival. An ecosystem is a community of living organisms. An ecosystem maintains an important balance in order for all organisms within the ecosystem to survive. The balance involves carbon‚ food‚ nitrogen‚ oxygen and water. The sun supplies the energy needed by ecosystems. Plants absorb the energy and use photosynthesis to convert it to sugar. There are nutrients in the air‚ soil and water

Body Systems Intergumentary- The integumentary system consists of the skin‚ hair‚ nails‚ glands‚ and nerves. The main function is to act as a barrier to protect the body from the outside. It also retains body fluids‚ protects against disease‚ eliminate waste products‚ and regulates the body temperature. Cardio Vascular- The cardiovascular system carries blood‚ oxygen‚ and nutrients to organs and tissues of the body. It also carries waste and carbon dioxide from these tissues for removal from

Kierra Roberts 1-4-11 11B How Do Batteries Work? Electricity is the flow of electrons through a wire‚ that is called a circuit. Batteries have three parts to them‚ an anode‚ a cathode‚ and an electrolyte. The cathode and the anode are hooked up to an electrical circuit. The chemical reaction that is happening causes the electrons to build up at the anode. When the circuit is closed the electrons will be able to get to the cathode. When the electrochemical process change the

causing clouds. Then the clouds rained. One thousand years of continuous raining caused oceans which made earth like it is today. Planet Earth‚ also known as the blue planet‚ has oceans covering three quarters of the Earth’s surface. Oceans have a system to try and keep the water temperatures even‚ whether or not the climate is the same. This is called the ‘Thermohaline Conveyer’. This is when water from the Tropics (warm water) is pushed towards the Poles where there is cold water and that water

damage the body. Free radicals are primarily a by-product of oxygen. During aerobic metabolism‚ each cell in the body utilizes oxygen to make energy so that it can do its job. Just as burning wood forms smoke as a by-product‚ the body creates by-products called free radical oxidants‚ or free radicals‚ when cells burn oxygen. These dangerous free radicals cause extra oxygen to damage cells in the body as they react to molecules in and around the cells. A free radical floating around in the body seeks another

Body Systems Michele Frizzell HCS/212 March 22‚ 2014 Brenda Young Body Systems Several systems in the human body maintain its proper function. These systems fight disease and infection; maintain proper blood flow to lungs and body‚ and dispose of any waste that the body no longer needs. Learning how each system works was educational and quite amazing. Our immune system fights off bacteria‚ viruses‚ and disease. Our environment if full of harmful toxins that our bodies are subject to daily

The body systems The Musculoskeletal system consists of the bones‚ muscles‚ ligaments and tendons. It provides structural support for the entire body. The musculoskeletal system allows and controls movement. The Cardiovascular system is responsible for transporting and removing gaseous waste from the body. The cardiovascular system is made up of your heart‚ blood vessels (arteries‚ veins‚ capillaries) and blood. The four major functions of the cardiovascular system are: To transport nutrients‚
