Explain the effects of osmosis on cells and tissues:
viva [34]

Answer:

In explanation.

Explanation:

Effect of osmosis on cells:

-Osmosis is the movement of water across a cell membrane. Cells use osmosis to maintain concentration equilibrium (the concentrations of solute inside and outside the cell are equal). Changing the amount of water allows the cells to achieve equilibrium.

Effects of osmosis on tissues:

-Red blood cells placed in a solution with a higher water concentration compared to their contents (eg pure water) will gain water by osmosis, swell up, and burst. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.

Hope this helps.

Give two reasons why it is better for human muscle cells to produce energy through aerobic respiration than through anaerobic re
NISA [10]
Anaerobic respiration (without oxygen) would caused muscle cells to produce lactic acid. This causes the muscles to ache and in the long term, damages them. Also anaerobic respiration releases far less energy (ATP) than aerobic respiration. So it is best for muscle cells to respire aerobically as they need more energy.
