In general, cellular response to stimuli is defined as a change in state or activity of a cell in terms of movement, secretion, enzyme production, or gene expression. [9] Receptors on cell surfaces are sensing components that monitor stimuli and respond to changes in the environment by relaying the signal to a control center for further ...
Adaptation can occur in anticipation of change or be a response to those changes. [138] For example, artificial snow-making in the European Alps responds to current climate trends. The construction of the Confederation Bridge in Canada at a higher elevation takes into account the effect of future sea-level rise on ship clearance under the ...
In fact, all three things may occur in sequence. Of these three effects only genetic change brings about adaptation. When a habitat changes, the resident population typically moves to more suitable places; this is the typical response of flying insects or oceanic organisms, which have wide (though not unlimited) opportunity for movement.

Several theories exist as to why and how behavioral change can be affected, including behaviorism, Self-efficacy theory, and the stages of change model. [1] Behavioral change can be very beneficial to an individual. Two such theories on the subject include behavior modification theory and cognitive behavioral theory.
Organisms are free to change back and forth between the response alternatives at any time. Concurrent-chain schedule of reinforcement' – A complex reinforcement procedure in which the participant is permitted to choose during the first link which of several simple reinforcement schedules will be in effect in the second link. Once a choice has ...
