An example of potential energy is A) a coiled spring. B) running water. C) tree branches blowing in the breeze. D) a moving elevator. E) electrical energy. Points Earned: 1.0/1.0 The correct answer is A. The definition of potential energy is an inactive type of energy that is stored for future use. All of these answers describe active energy‚ for example‚ running water is very active but can generate other types of energy. Which one of the following substances will float in gasoline

some of the main concepts or components of psychology. Psychology helps in solving the problems and issues involving different areas and it is often used as addressing mental issues. It not only helps the humans‚ but also the animals/ birds. Thermoregulation‚ thirst‚ etc. of animals can be known through the process of psychology (Reynolds‚ Wilson‚ Austin & Hooper‚ 2012).

normal level; it does this by turning the corrective measures off. Homeostasis uses the principle of negative feedback in order to maintain a constant internal environment. There are a number of different examples of negative feedback such as thermoregulation‚ regulation of blood glucose and the regulation of water potential. The control of the heartbeat can also use negative feedback mechanisms. In mammals a constant body temperature is maintained using the part of the brain called the hypothalamus

Running the Race to Obtain the Prize? Each year athlete’s ability to perform seems to increase by leaps and bounds. Some reasons for this can be attributed to better training methods‚ better conditioning techniques‚ and better over all health of the athlete. While most situations involve one or more of the previously scenarios‚ some athletes always seem to take it to a step further. They engage in a process called blood doping. This procedure does increase physical performance and athletic

natural environment. If our internal body temperature was to rise or fall even a few degrees centigrade our body would not be able to carry out its everyday functions efficiently and this could lead to loss of ability to function at all. Therefore thermoregulation is very important and water plays a part in this. One method of reducing internal body heat is sweating; sweat is mostly made up of water. The structure of the water molecule means that it has very high melting and boiling points for a molecule

Homeostasis What is it? Maintenance of a relatively constant internal environment The human body is constantly responding to internal and external factors in order to maintain relative stability within the body Homeostasis is vital to the body as a whole‚ right down to each individual cell. If homeostasis is not maintained at the cellular level this will affect the body as a whole. History Claude Bernard (1813-1878): consistency of internal environment is the condition for free life.
