The sodium-potassium pump does not do which of the following actions? maintains the cell's physiological needs by establishing an electrochemical
moves sodium molecules against their concentration gradient into the cell using ATP
moves potassium molecules against their concentration gradient into the cell using ATP
moves sodium molecules against their concentration gradient out of the cell using ATP

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
