  1. Tonicity: hypertonic, isotonic & hypotonic solutions (article) | Khan ...

    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.

  2. Hypotonic, isotonic, and hypertonic solutions (tonicity)

    In an isotonic environment, there is the same amount of water on each side, 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 …

  3. Hypotonic, isotonic, and hypertonic solutions (tonicity)

    In an isotonic solution, there is no net flow of water, keeping the cell stable. In a hypertonic solution, water leaves the cell, causing it to shrivel. These reactions are due to the semipermeable nature of …

  5. Introduction to plate tectonics (video) | Khan Academy

    Earth's lithosphere is broken up into tectonic plates, which move slowly over time. Evidence like matching coastlines and same-species fossils on different continents support this. A plate boundary …

  6. Khan Academy

    Osmosis and tonicity. Hypertonic, isotonic, and hypotonic solutions and their effect on cells.

    कोशिकाएं अल्पपरासारी (Hypotonic), समपरासारी ( Isotonic) और अतिपरासारी (Hypertonic) विलयनों में अलग-अलग प्रतिक्रिया करती हैं। अल्पपरासारी विलयन में ...

  8. Osmosis, osmolarity, and tonicity (article) | Khan Academy

    If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell’s volume will remain stable. A solution is considered isotonic if its solute concentration is the …

  9. Hypotonic, Isotonic and Hypertonic (video) | Khan Academy

    Let's understand Hypotonic, Hypertonic and Isotonic solutions! Created by Skyloom (Dubbing).

  10. Diffusion and osmosis (video) | Khan Academy

    Diffusion refers to the movement of molecules from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion specifically for water molecules moving across a semi …
