The sodium-potassium pump system moves sodium and potassium ions against large concentration gradients. It moves two potassium ions into the cell where potassium levels are high and pumps three sodium ions out of the cell and into the extracellular fluid.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression

explanation:

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.
