Homeostasis is the maintenance of a constant internal environment of a cell or an organism‚ despite fluctuations in the external environment of that cell or organism. The internal environment is set to function at its optimum rate - and it is dependent on variables such as body temperature‚ blood pressure and blood sugar levels. These need to be maintained despite changes in the external environment as well as the extent of activity and the diet of the organism. These variables are controlled by

is very slowly growing thicker. Volcanic activity is continually adding mass to the crust. Though the crust is solid it is made up of about 12 plates. They are called Tectonic Plates. These plates are in constant motion. The movement is caused by convection currents in the mantle. The movement is very slow‚ averaging about 2 inches a year. This is about like the growth of your fingernails. * The crust is about 0.5 % of the earth’s total mass. * The crust is made up of silicate rocks such as

that help to ensure good ventilation: * Open windows – ventilation may simply involve opening windows to allow stale air out and fresh air in. This is most effective if windows are opened in both lower and upper levels of a building‚ as natural convection currents will make warmer‚ stale air leave the building at the top to be replaced by colder‚ fresher air at the bottom. * Fans – whether mounted on ceilings or standing‚ fans assist in the movement of air by replacing stale air with fresh air

Astronomy Review Structure: * The quiz will be similar in format to the first quiz we had in physics. For most questions you can choose the most appropriate way to answer‚ sentences‚ point form‚ calculation‚ graphic organizer. Major concepts to understand: * The Big Bang Theory * The Nebular model * The galaxy * The solar system (including the planets) * Distances in space * Our Sun (layers and solar events) * General properties of stars (luminosity‚ heat)

Maria Martinez Anatomy and physiology II TTH 2:20 “Demonstrating the Importance of Surfactant: Lab Report” Introduction Surfactant is an essential component for the respiratory system to function properly. This experiment was administrated to help us understand better the role of surfactant in the alveolar system. Surfactant is a detergent-like substance produced by the Type II alveolar cells in the alveoli. Surfactant is produced to make it easier for people to breath by reducing the surface

The following are some of them: Setting/location: The location used for this genre of a film is isolated and lonely area that has been abandoned or an area where the victim will feel vulnerable.

are less the 200 million years old. Therefore‚ the reservoir rocks are younger than the start of the Pangaea breakup. 7. Explain the main driving force behind Plate Tectonics. (5 points) The main driving force behind plate tectonics is convection. The mantle is liquid so it moves in a circular motion that drives Earth’s crust to move. The mantle behaves like water would if you were boiling water. 8. A mnemonic is a word trick that helps you to remember a sequence of information.
