<u>Answer:</u>
<em>Sodium will move from the inside of the cell to the outside of the cell by diffusion.
</em>
<u>Explanation:</u>
A <em>difference in concentration of a substance</em> in two regions induces movement of that substance from the area of high concentration to the <em>area of low concentration</em>. Since the movement is according to a concentration gradient there is no need for energy expenditure. <em>This is called passive diffusion.
</em>
In this case passive diffusion of sodium will occur. If a substance has to be moved against its concentration gradient energy is required and this p<em>rocess is called active diffusion.

ok, good for Beth, but where is the question??
Answer:
Genetic variation
Explanation:
Drift and natural selection are natural phenomena that occur when there exists genetic variation. In the first case (drift), the consequence will be the decrease in the genetic diversity, while natural selection will change the allele frequencies in order to favor adaptive genetic differentiation
Isotonic, Hypotonic, and Hypertonic Solutions. Water moves readily across cell membranes through special protein-lined channels, and if the total concentration of all dissolved solutes is not equal on both sides, there will be net movement of water molecules into or out of the cell.
Answer:
Today, drug-resistant infections are a serious threat to people's health. Hundreds of thousands of lives are lost every year because of infections that can no longer be treated with existing drugs. Discovering new antibiotics, able to kill drug-resistant bacteria, is essential to saving modern medicine.
