Answer:
Water
Explanation:
In simple words, the volume of a cell refers to <u>the amount of water it contains</u>.
In eukaryotic cells may change their volume according to the effects of either the loss or gain of water. Furthermore, these changes in cell volume are extremely important as they work as a signal for different cell processes such as migration, proliferation, or death.
Therefore, the change of cell volume is principally due to the loss or gain of <u>water</u>.

Somatic cells are produced through the cell division process of mitosis. ... Cells with two copies of each chromosome are called diploid. Sperm and egg cells, called gametes, are formed through meiosis, which is a slightly different cell division process that results in the cells having only one copy of each chromosome.

Answer:
Somatic mutations are mutations that occur in body cells, that is the cells that do not make gametes. These mutations are not passed on to further generations; for example, if a mutation that changes a gene in a skin cell would not affect your children because skin cells don't produce gametes.
