Based on the Nernst equation, the equilibrium potential for any ion (Eion) distributed across a membrane is dependent on the internal (Ion_in) and external (Ion_out) concentrations of the ion (in moles or grams/liter), the valence of the ion, z (an integer), the absolute temperature (°K), Faraday’s constant (96,500 coulombs/mole) and […]

In parakeets, two genes control feather color. One of the genes determines whether a yellow pigment is made, and the other determines whether a blue pigment is made. If both the yellow and blue pigments are produced, the feather color is green. If no pigment is made, the feathers are […]
