<span>The correct answer is Sexual Reproduction. Unlike cell division, sexual reproduction creates new offsprings instead of copies of the biological parents and there is a time period that takes for the fetus to mature and grow inside the womb before birth. Unlike this, cell division is easy and fast and just creates a copy of the previous cell.</span>

The correct answer would be D) An observation that has a number associated with it.
Answer:
The cells need water to maintain their metabolic functions, the way water enters through cells membranes is by osmosis.
Explanation:
The cell membrane is a lipidic bilayer composed of phospholipids and embedded proteins. Phospholipids have the characteristic of being amphiphilic which means that possess hydrophilic and lipophilic characteristics. The most common way is by osmosis, that is a mechanism that moves water from high concentration to less concentration of water. In the cell membrane, there are is channels of proteins called aquaporins that facilitate the pass of water through the membrane. Also, as water is a very small molecule without charge, this characteristic allows passing a limit amount of water molecules through the hydrophilic characteristic of membranes.
