Survival: Water's Impact on Cell Function
- Humans can only survive about 3 days without fluids, making the decision of whether to drink sea water crucial in survival situations.
- Cells have specific conditions in which they can survive, exploring the effects of hypertonic, hypotonic, and isotonic solutions on cell function.
- Cell membranes are selectively permeable, allowing water molecules to pass through special protein channels called Aquaporins based on concentration levels.
- Placing a cell in hyper-tonic, hypo-tonic, or isotonic solutions results in different movements of water molecules, affecting cell size and survival, with sea water being a dangerous hypertonic solution due to its high salt concentration.
