For example, if I want to earn the equivalent of $30 per hour for a 40 hour work week, but I can only bill 20 hours, I have to bill $60 per hour. I am still working 40 hours per week, but only 50% can be billed to a client so my billable rate doubles.

In tropisms, this response is dependent on the direction of the species.The word tropism comes from the Greek trope (to turn or to change).ropisms.

In physiology, a stimulus (plural stimuli) is a detectable change in the internal or external environment. The ability of an organism or organ to respond to external stimuli is called sensitivity.When a stimulus is applied to a sensory receptor, it normally elicits or influences a reflex via stimulus transduction.he endocrine system is affected largely by many internal and external stimuli. One internal stimulus that causes hormone release is blood pressure. Hypotension, or low blood pressure, is a large driving force for the release of vasopressin, a hormone which causes the retention of water in the kidneys.
