1. a. The action potential changes the membrane potential from -70 mV (resting) to +30 mV and back again to the resting membrane potential. b. This results from a change in membrane permeability first to Na then to K due to the opening of what type of ion channels? Voltage gated channels 2. a. Where is the density of voltage-gated Na+ channels the greatest? Axon hillock b. What areas of the neuron generate signals that open these voltage-gated channels? Dendrites and the cell body c. Opening

The ecological theory of development that was proposed by Urie Bronfenbrenner (1917-2005)‚ is relevant to state all of our lives. Bronfenbrenner’s research demonstrates how our development is affected by the environment in which we live. The model consist of five major systems; microsystem‚ mesosystem‚ exosystem‚ macrosystem‚ and chronosystem. "Ecological systems theory is an approach to study of human development that consists of the scientific study of the progressive‚ mutual accommodation‚ throughout

this policy is linked to ecological family systems theory. In this theory families do not operate alone‚ the functions in which families perform are in alliance with other institutions such as formation and dissolution‚ economic systems (insurance)‚ educational systems‚ healthcare systems‚ legal systems‚ support systems‚ mediating systems and media.

It attempts to explain that the individual use of media is a goal oriented activity and the overall intensity of the dependency relationship between individual and media
