A larger molecule or a polar molecule that cannot passively diffuse through the cell membrane would most likely be actively transported. Examples include glucose, ions (such as sodium and potassium), and amino acids.
Shared electrons in a water molecule are most likely found in the covalent bonds between the oxygen and hydrogen atoms. In water, the oxygen atom shares electrons with the hydrogen atoms to form two polar covalent bonds.
A nonpolar molecule, such as oil, would be least likely to completely dissolve in water due to the difference in polarity between the two substances. Nonpolar molecules are hydrophobic and do not easily mix with water, which is a polar solvent.
A compound that is likely not a gas at room temperature would be a larger molecule with higher molecular weight, such as a long-chain hydrocarbon or a complex organic molecule. These molecules have stronger intermolecular forces holding them together, making them more likely to be in a liquid or solid state at room temperature.
Both the quantum model of the atom and John Dalton's model would predict that a methane molecule is composed of one carbon atom and four hydrogen atoms bonded together. They would also predict that the molecule is nonpolar due to the symmetry of the tetrahedral shape formed by the hydrogen atoms around the carbon atom.
Uracil would base pair with adenine on a RNA molecule.
A molecule would be actively transported when an equal concentration of solutes exist on either side of the cell membrane.

Large carbohydrates such as glycogen, starch will not be transported in to the cell by cell membrane.

Coal from Newcastle to a factory in Stoke would likely be transported by rail or canal.

an ion
A molecule of CH4 (methane) is more likely to exist in nature because it is a stable compound with all valence electrons satisfied through covalent bonding. A molecule of CH3, on the other hand, would be highly reactive due to the presence of an unpaired electron on the carbon atom, making it less likely to exist in nature.

Shared electrons in a water molecule are most likely found in the covalent bonds between the oxygen and hydrogen atoms. In water, the oxygen atom shares electrons with the hydrogen atoms to form two polar covalent bonds.
