Considering the definition of volume, the volume of a cube with a side length of 3 centimeters is 3 cm³.
<h3>Volume</h3>
Volume is a measure of the space occupied by an object in three-dimensional space.
In other words, volume of a geometric figure is defined as the amount of space occupied by the object or figure in three-dimensional space. Volume is measured in cubic units.
The volume of a cube is equal to the measure of its side to the cube. That is to say:
Volume = side x side x side = side³
<h3>This case</h3>
In this case, you have a cube with a side length of 3 centimeters. Replacing in the definition of volume:
Volume= 3 centimeters× 3 centimeters× 3 centimeters
Solving:
<u><em>Volume= 3 cm³</em></u>
Finally, the volume of a cube with a side length of 3 centimeters is 3 cm³.

Answer:
1. Potassium
2. increasing towards zero
3. hyperpolarization
4. voltage-regulated Potassium
Explanation:
Membrane potential can be defined as the difference in electric charges inside and outside of a cell. The resting membrane potential (RMP) occurs when there is no net current across the membrane and therefore the cell is in a non-excited state. At the RMP, sodium ions (Na+) are more concentrated inside the extracellular fluid (ECF) than inside the intracellular fluid (ICF), while potassium ions (K+) are more concentrated inside the ICF. The diffusion of K+ outside the cell triggers its hyperpolarization, by becoming the membrane potential more negative compared to the resting potential. As the potential nears +35 mV, the voltage-regulated potassium channels are open, thereby K+ ions leave the cell down its concentration gradient, while voltage-gated Na+ channels become saturated and inactivate.

Explanation:
When a plant opens and closes its stomata, it is maintaining homeostasis. Homeostasis includes the regulation of carbon dioxide and water levels necessary to perform photosynthesis. It also allows the plants to store water to prevent them from dying
