<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.
</em>
<u>Answer</u>: Natural selection.
<u>Explanation</u>:
- The concept of <em>natural selection</em> was given by <em>Charles Darwin.</em>
- According to this concept, in a given environment the organisms that possess <em>better adaptations</em> have<em> higher chances of survival</em> and, leave behind a <em>greater number of progenies</em>.
- When malaria outbreak occurs, the allele frequencies change and only the organisms that possess the alleles which help them to <em>survive</em> this outbreak due to resistance against malarial infection will be selected by nature and<em> hence, this is an example of natural selection.</em>
