Paper Photosynthesis is the process that captures energy from sunlight and make sugars to store for chemical energy‚ whereas cellular respiration is the process that releases chemical energy from sugars and other carbon-based molecules to make ATP when oxygen is present. In addition‚ cellular respiration takes place in both plant and animal cells while photosynthesis only takes place in plant cells‚ but that doesn’t necessarily mean it’s less important to animals in the long run. Photosynthesis is

growth of the cells in the human body and the ability of these cells to migrate from the original site and spread to distant sites. If the spread is not controlled‚ cancer can result in death. 2.How does cancer occur? The body is made up of trillions of living cells. These cells grow‚ divide‚ and die in an orderly fashion. This process is a tightly regulated one that is controlled by the DNA machinery within the cell. When a person is a baby or a child or within his or her mother’s womb‚ cells divide rapidly

rapidly. With early detection and proper treatment‚ melanoma has a high cure rate. Early detection and treatment are possible because melanoma typically begins on the surface of the skin. It develops when melanocytes are damaged‚ which causes these cells to grow uncontrollably. As melanoma develops where melanocytes occur‚ this cancer can begin on the skin‚ under a nail‚ and even in an eye or on a mucous membrane.The type of treatment a doctor will recommend to a melanoma sufferer depends on the stage

Solar Powered Traffic Light Solar traffic lights are signaling devices powered by solar panels positioned at road intersections‚ pedestrian crossings and other locations to control the flows of traffic. They assign the right of way to road users by the use of lights in standard colors (red - amber/yellow - green)‚ using a universal color code (and a precise sequence to enable comprehension by those who are color blind). Most of the solar traffic lights have battery back-up for functioning during

Stars A star is a massive‚ luminous sphere of plasma held together by gravity. The nearest star to Earth is the Sun‚ which is the source of most of the energy on the planet. Solar System The Solar System consists of the Sun and its planetary system of eight planets‚ their moons‚ and other non-stellar objects. It formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. The vast majority of the system’s mass is in the Sun‚ with most of the remaining mass contained

Simple energy balance models are derived and used to illustrate the fundamental mechanisms behind variations of temperature with altitude‚ latitude‚ and season. The global annual mean energy balance is then presented and briefly discussed. Finally‚ the origins‚ thermodynamic structure‚ and composition of the atmosphere and ocean are summarized.
