The correct answer is : the sodium ion and glucose both shows the facilitated diffusion.
Explanation:
Facilitated diffusion is form of diffusion of molecules of solutes with the help of transport proteins along their concentration gradient on the plasma membrane, however it is a passive transport as its does not require energy to move in or out of cell.
Oxygen can move through the membrane directly by simple mean of diffusion. however, Other molecules like amino acids, ions, glucose and many more need a integral pore, channel or transport molecule to pass through the membrane or with facilitated diffusion.
Glucose transporters involves to help in movement of glucose through the membrane along the concentration gradient it shows facilitated diffusion. Sodium ions also move through along concentration gradient by protein channels formed by transport proteins through hydrophobic membrane.
Thus, the sodium ion and glucose both shows the facilitated diffusion.
The gas that is most likely to attain a speed greater than the earth's escape velocity is hydrogen.
The root - mean - square velocity of a gas depends on the temperature as well as the molar mass of the gas. We are told that the escape velocity of the earth is 11 km/s.
The gas that will move at such speed must be a very light gas. Hence the gas that is most likely to attain a speed greater than the earth's escape velocity is hydrogen.
Tertiary structure is the overall three-dimensional structure resulting from folding and covalent cross-linking of a protein or polynucleotide molecule. This is what is explained in this question.

This question is quite a controversial one, because three of the options represented above are very similar, but due to the fact that there is a HF, which is even more polar that water, it is getting clear. So, the right answer is definitely the first option, because HF belongs to acids that are very polar compounds.
