Answer: If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. Image credit: Mariana Ruiz Villareal.

Meanwhile, reservoir refers to the living and reproductive habits of said infectious organism.
The portals of infection include any form of entry or exit that the infectious agent may have used. These can include:
Respiratory tractUrinary and reproductive tractsEyes EarsSkinThe transmission component refers to the way in which the infection can be transmitted. This can range from airborne transmission and contact to non-contagious agents. Finally, immunity refers to all factors that stop the spread of the agent, be they natural or man-made barriers like masks.
