No, because it would probably keep your brain up.
Physical weathering works with mechanical forces, such as friction and impact, while chemical weathering takes place at the molecular level with the exchange of ions and cations.
The answer is true. They cannot only replicate themselves within cells, but they cannot outside of a cell.
When placed into an hypertonic solution, animal cells will shrivel up, while plant cells will stay firm thanks to their air-filled vacuole. In a hypotonic solution, the cells will take on water and appear more plump. In an isotonic solution, they'll stay the same.
