In chemistry, a stressor is something that either speeds up a reaction rate or keeps the reaction rate the same. Stressors include light, temperature and elevated sound levels. Stressors also include the phenomena of substance concentration (does not shift equilibrium), catalysis, substance surface area (speeds up the reaction rate), and the nature of the reactants. In accordance with Le Chatelier's Principle, reactions shift away from stressors. For example, see the following equilibrium reaction. There are three distinct species: CO, H2 and CH3OH. CO + 2H2 ↔ CH3OHIf the concentration of any of these species is changed, the reaction will shift accordingly. If [CO] is increased, the reaction will progress towards the products. If [CH3OH] is increased, the reaction will progress towards the reactants.
In organismal biology, a stressor is an external state change (such as a change of temperature or salinity) that results in a physiological response from an organism required to maintain homeostasis. Many organismal traits are occult until revealed by observing responses to stressors; this is particularly true of microorganisms. From Wikipedia under the

Your mind has a powerful role in how you react to stressful situations Answered by Relaxyourself - Mon Jun 2 18:01:56 2008 teenage relationships are a joyous time and are not considered a stressor.? Q. eating a proper diet,arguing with friends and family,doing poorly on a test Asked by Sharese E - Mon Dec 8 11:42:36 2008 - - 1 Answers - 0 Comments A. It's not clear what your question is. However, I sense some sarcasm in your question, in that people say teenage relationships are a joyous time, when in fact they are often not, especially given the reasons you cited below. I can relate. Erroneous and misguided baby boomer adults often point to one's youth as the best years of your life, and as a "rite of passage". They couldn't be more wrong. These years are certainly important, but the power they hold comes not in pure joy but the strength gained from the incredible pain one endures during the difficult transition to adulthood. These years are not easy, and they may scar you. But the difference between letting the teenage years destroy you and learning and growing from them is by being… [cont.] Answered by nickname - Mon Dec 8 11:55:59 2008 Has anyone ever seen a bride and groom fighting on their wedding day?
