The passive transport used by water molecules to move across a cell membrane is called Osmosis.

In the case of water molecules, they do not require any specialized help to cross the cell membrane, for this reason, option B which indicates diffusion through the help of carrier proteins, is false. Option C is false as well given that Endocytosis is a form of active transport.

The remaining options are Diffusion and Osmosis. Though very similar, there is one key difference between the two. Diffusion occurs when particles move from a place of higher concentration to a lower concentration point, in order to achieve equilibrium.

The difference from Osmosis is that in Osmosis, the solvent particles can move without the need for other particles to move. This is the case for the small water molecules and because of this, the correct option is A.

Vlad [161]

It is mRNA because RNA, which stands for ribonucleic acid, is a polymeric molecule made up of one or more nucleotides. ... During the process known as transcription, a RNA copy of a segment of DNA, or messenger RNA (mRNA), is made. This strand of RNA can then be read by a ribosome to form a protein.
