The answer to this question is <span>membrane potential
The gradient of electrolyte concentration from inside cell and outside cell will determine the membrane potential. Natrium or sodium is much higher outside the cell than inside cell. In contrast to the sodium, potassium is much more inside cells. This two electrolyte have major role in the membrane potential and action potential. </span>

Answer:
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
Answer:
C. You can see the parts in a heterogeneous mixture but can't see them in a homogeneous mixture.
Explanation:
a heterogeneous mixture is in other words, the one that does not mix or is not uniformly combined, hence leading to the creation of layers of the substances used.
a homogeneous mixture is the one that completely dissolves, or mixes, or is uniformly combined.
They breathe through their skin. Air dissolves on the mucus of their skin, so they MUST stay moist to breathe.
If worms dry out, they suffocate. As fresh air is taken in through the skin, oxygen is drawn into the worm's circulatory system, and the worm's hearts pump the oxygenated blood to the head area.
