The correct answer is option d, that is, leak channels.
The cell membrane comprises protein channels known as leak channels, which permits sodium and potassium ions to leak down their concentration gradients. The membranes of the cell are significantly more permeable to potassium ions in comparison to the sodium ions, due to the presence of more K+ leak channels than Na+ leaks channels.
The reason as to why most common observers of the ocean fail to observe ocean currents is because ocean currents take place under the water. Ocean currents are seasonal movements of sea or ocean waters generated by forces acting upon the mean flow, such as wind, the breaking waves, salinity differences, cabbing among others.
