- The balance between the chemical and electrical forces pushing potassium through potassium channels and across the membrane is represented by the potassium equilibrium potential.
- At the equilibrium potential of potassium, which is -80mV, there is no net movement of potassium ions.
<h3>At potassium's equilibrium potential, what happens?</h3>
- At equilibrium, the electrical potential gradient across the membrane precisely balances the gradient of K+ concentration.
- There is no net migration of K+ from one side to the other, despite the fact that K+ ions continue to traverse the membrane via channels.
<h3>How does potassium diffuse in order to influence the membrane potential?</h3>
- Potassium ions will flow down their concentration gradient, or towards the exterior of the cell, because the membrane is permeable to them.
- Although the membrane is not permeable to sodium, there is a concentration gradient that favors sodium diffusion in the opposite direction.

The giraffe head is higher than its heart so the blood pressure in the head must be lower than in the heart. The pressure is directly related to the density, gravity, and the height. The calculation would be:
<span>P = ρ*g*h
</span>P= 1.05* 10^3 kg/m3 * 9.8m/s2 * 2m= <span>20 580 pascals= 20.58 kpa</span>
Answer:
In plant cell there present an important organelle, chloroplast that converts sunlight energy into energy during light and dark reaction.
The answer would be A. carbohydrates (carbs) because carbs are generally composed of sugars and glucose (as an example) has the ratio between carbon, hydrogen and oxygen in a 1:2:1 ratio in its form: C6H12O6
Weathering causes the granite to break down into small particles - sand. The sand becomes buried and compacts into sandstone. If the sandstone continues to be buried and comes into close contact with high heat, such as magma, it can be turned into quartzite.
