(c) Hypertonic solution
List

the unrelength of a sound wave whose frequency is 220 Hz and speed is 440​

Answer 1

Answer:

Hypotonic solution-Hypotonic solutions have more water than a cell. Tap water and pure water are hypotonic. A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.

Isotonic solution-In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. 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.

Hypertonic solution-If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ...
