According to the cell theory, all cells come from ______________ cells.
Explanation
According to the cell theory, all cells come from preexisting or pre-existing cells. This principle states that cells are the fundamental units of life and that all living organisms are composed of cells. The theory also proposes that cells can only arise from preexisting cells through cell division. This concept has been supported by numerous scientific observations and experiments, providing evidence for the continuity of life and the importance of cell reproduction.Rate this question:

If the concentration level inside a cell (the egg) is 20% salt water and the outside concentration is 40% salt water the cell (egg) will gain in mass.
-
True
-
False
Correct Answer
A. TrueExplanation
When the concentration level inside a cell is lower than the outside concentration, the cell will gain mass through osmosis. In this case, the cell (egg) has a concentration of 20% salt water inside and the outside concentration is 40% salt water. Since the outside concentration is higher, water molecules will move from the outside to the inside of the cell, causing it to gain mass. Therefore, the statement "the cell (egg) will gain in mass" is true.Rate this question:
