Incorrect statement is: Type II membrane proteins have a signal sequence targeting them to the ER as well as a signal anchor sequence.
Signal peptide or signal sequence is a sequence of amino acids that gets recognized by signal recognition particle (SRP). This sequence is involved in cotranslational translocation into ER, where the protein should be folded. A stop-transfer sequence signals that translation of the protein should continue in the cytosol (not in ER). A signal anchor sequence signals the insertion of protein into the ER membrane.

<u>Answer:</u>
The process of "Osmosis" is modeled in the plant cell diagrams seen here.
<u>Explanation:</u>
Osmosis is the natural gross migration of solvent particles into a zone of higher solute concentration via a selectively permeable membrane, in the path that seeks to balance the amounts of solvents on both the ends. Osmosis as biological membranes are semipermeable, is a critical mechanism in biological systems.
Such membranes are usually impenetrable to massive and polar molecules like polysaccharides, ions and proteins while being porous to hydrophobic or non-polar molecules like lipids and to small molecules as carbon dioxide, oxygen, nitric oxides and nitrogen.
