Move three sodium ions out of a cell and two potassium ions into a cell while consuming an atp for each cycle
Explanation:
By pumping three (3) Na+ to the outside and two (2) K+ to the inside of the cell, there is a net positive charge on the outside leaving the inside of the cell electronegative. This process is achieved by the Na+/K+ pump and is a process that consumes ATP energy.
This is much more important in a neuron cell who ¾ of its energy is used to maintain a -70mV resting potential that is important for the nerve to pass impulse when depolarised.
In other cells, the gradient created in important in maintaining the homeostatic osmolarity inside the cell to avoid swelling and lysis of cells due to uptake of excess water by osmosis. The Na+ gradient is also used to import other molecules into the cell such as glucose and amino acids. These molecules are coupled with Na+ and then are absorbed efficiently as the Na+ flow back inside the cell down the Na+ concentration gradient.

I could help you if you attach a picture of the gel electrophoresis!!
Answer:
Slump creep and weathering
Explanation:
Freeze-thaw weathering occurs when water from rainfall or melt snow penetrate into cracks and the temperature is lowered than a liquid and freeze. The process where exposed rock is broken. It gives the landscape a new shape.
When the freeze occur it expands the rock and when the temperature increases above freezing the thaw ice further penetrate into the crack.
Weathering the breaking down of rock into smaller frequent affects freeze-thaw as it allows water to penetrate into cracks.
Slump is the downward movement of materials from rock surface, it allows material to move alone the rock surface liquid such as water can be allowed to move and penetrate cracks. crack rock fragment that results from freeze thawing are deposited at rock base and form smaller rocks
Creep is also the movements of weathered materials down the slope of rock surfaces. It could result from freeze thaw.
<span>In the "all or none" law of muscle contraction, it states that when the stimulus applied exceeds threshold then the the nerve sending signals to a few muscle fibers will give a complete response; contraction. Graded response is dependent on how many motor units have been recruited. The more motor units, the greater the force in the contraction.</span>
