Population growth is the increase in the population number of a given species in a time. Longevity, migration and fertility rates affect population growth.
<h3>What are the factors affecting population growth?</h3>
<u>Increased Longevity</u> has impacted the population growth as the life expectancy has resulted in the accumulation of more people as their age of living has increased.
<u>International Migration</u> can affect the population growth positively and negatively as moving of the person from one region will decrease its population growth while the region where they go will have increased population.
<u>Fertility Rates</u> has a great impact on the population as the fertility rate had decreased due to many factors and the population has declined.
Therefore, option A. longevity option B. migration and option C. fertility rates influence the population growth.

If NaCl concentration is higher outside the cell than inside the cell, and the osmolarity of the cell is higher than that of the solution surrounding the cell then Overall, the cell will take up water because it is hypertonic.
- Osmosis is the transfer of a solvent from a region of lower solute concentration to a region of higher solute concentration through a semi-permeable membrane.
- The dissolved solutes—the sodium and chloride ions that make up salt—cannot traverse the barrier but the water in the surrounding solvent can enter the membrane.
- In these circumstances, water from the solute environment will cross the membrane to balance the solute content on each side.
- When there are more solutes outside the cell than inside it, an environment is said to be hypertonic for cells, and it is said to be hypotonic for cells where there are fewer solutes outside than inside the cell.
- There is no net water movement when solute concentrations are the same on both sides of the cell, and the cell is referred to as isotonic.
hence , here the cell is hypertonic thus the cell will take up water and swell but the solutes like NaCl will not enter the cell.

C, hydrogen bonds , i did this test last year and im in chemistry now, so its hydrogen bonds.
I believe the answer is natural selection..plse dbl check...
