Question: "which organelles are usually found in both plant and animals cells"
Answer: plasma/cell membrane
hope this helps have a fanstatic day :D
C-Mitosis
Cells make new cells by going through a phase called mitosis.

Potassium ions act as if they were nonpenetrating solutes in the intracellular fluid and as sodium, chloride, and ions in the extracellular fluid. they are pumped back out because
<h3>What is the Na+- K+ pump's principal function in preserving the resting membrane potential ?</h3><h3 />
The Na+ K+ -ATPase pump helps living things maintain their osmotic equilibrium and membrane potential. The sodium and potassium withstand concentration gradients. The Na+ K+ -ATPase pump maintains the gradient between a higher concentration of sodium extracellularly and a higher concentration of potassium intracellularly.
- A change in K+ conductance would have a greater effect on the resting membrane potential than a change in Na+ conductance because the membrane is more permeable to K+.
- If the extracellular potassium ion concentration decreased, more potassium would leave the cell, causing the electrical gradient across the membrane, or transmembrane potential, to increase. This state is known as hyperpolarization.

Answer:
Cells are so small that they weren't even discovered until the invention of the microscope. A cell is the basic unit of structure and function in a living thing.
Explanation:
You can see them under a microscope. Not that hard.
