Answer:
Each objective lens has a different magnification. Multiply the magnification of the eyepiece by the magnification of the objective lens to produce total magnification. For example, a 10X ocular lens and a 40X objective lens will produce a total magnification of 400X (10 x 40 = 400).
Answer:
The correct answer is b) When a plant cell is placed in concentrated salt water, water moves out of the cell.
Explanation:
Osmosis is the movement of solvent molecules from an area of less concentration of solute to high concentration of solute to equalize the concentration of both the side of the cell.
So water will move outside the cell when any cell will be placed in a concentrated salt water because the concentration of solute is high in salt water and low inside the cell.
Therefore when a plant cell is placed in salt water the osmosis of water takes place from inside to outside the cell. So the right answer is b.
Yes when fossil fuels are burned they release the carbon dioxide locked inside of them
that is why fossil fuels are a big source of global warming and we will eventually run out of fossil fuels
Hello!
I believe the best answer to your question would be Option C) excess carbon dioxide.
Hope this helps, and have a lovely rest of your day :)
