Ions have an extra or lost an electron. Isotopes have different numbers of neutrons.
The third answer because there are two of each atom
Answer:
Water outside the cell will flow inwards by osmosis to attain equilibrium
Explanation:
In the hypotonic environment, the concentration of water is greater outside the cell and the concentration of solute is higher inside. A solution outside of a cell has a lower concentration of solutes relative to the cytosol.
If concentrations of dissolved solutes are greater inside the cell, the concentration of water inside the cell is correspondingly lower. As a result, water outside the cell will flow inwards by osmosis to attain equilibrium.
Osmosis is a process by which molecules of a solvent tend to pass from a less concentrated solution into a more concentrated one through a semipermeable membrane.
Answer: The balance of the reaction shifts toward the endothermic reaction.
Explanation:
An ENDOTHERMIC REACTION requires input of HEAT ENERGY to drive it FORWARD from reactants, unto completion of products.
So, on increasing the temperature (available heat) the REVERSIBLE REACTION favors the shifts towards the endothermic reaction
