Explanation:
Atom Z has a full valence shell which makes it the most stable.
The similarity between the the DNA and RNA molecules is that both of them are long polymers and they are made up of nucleotides.
The differences between the two molecules are as follows:
1. The sugar components of the DNA molecule are deoxyriboses while the sugar components of the RNA molecules are riboses.
2. The nitrogenous bases in DNA molecule are adenine, guanine, thymine and cytosine while the nitrogenous bases in the DNA molecule are adenine, guanine, uracil and cytosine.
3. The back bone of the DNA molecule is made of the deoxyriboses and phosphate while the back bone of the RNA molecule is made up of riboses and phosphate.

Answer:
The correct answer is : The concentration of solute in the environment is equal to the concentration inside the cell.
Explanation:
Isotonic environment is an environment the amount of solute concentration is equal on both side of the semipermeable membrane or the cell. in such condition there would be no water movement towards particular direction or will take place and as there is no water movement so there would be no change in shape or size of the cell. The osmotic pressure in an isotonic environment would be same on both side of the membrane.
Thus, the correct answer is : The concentration of solute in the environment is equal to the concentration inside the cell.
