To maintain the Resting Membrane Potential of neurons at -70 mv. K diffuses out (into ECF) and Na move in (into ICF) through the leaky channels, but their concentrations are kept within the normal homeostatic range in the ICF and ECF by which mechanism?

All living cells have a (resting) membrane potential, but only excitable cells such as nerve and muscle cells are able to greatly change the ion conductance of their membrane in response to a stimulus, as in an action potential. Skeletal muscle constitutes 40% of muscle mass. Derangement of muscle function can have profound systemic effects.

Explanation:

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.
