Once replicated, they burst out of the cell by cytolysis, killing the cell in the process. As a … Continue reading How viruses help kill bacteria.
The Kidneys and Controlling Water Levels
Your body needs to be able to regulate its water levels to prevent cells from getting damaged. Due to osmosis, if your body has too much water, your body cells will swell up and burst. On the other hand, if your body doesn’t have enough water, cells will shrivel up and die. Thankfully, as a … Continue reading The Kidneys and Controlling Water Levels
