Hi again!
For the first question, we know that the water transformed into a gas. This fact eliminates choices C and D, primarily because they describe the change as "gas to liquid" instead of liquid to gas.
What separates B from A is that B is saying the liquid changed to a gas in response to sunlight, which is completely false and impertinent to the prompt.
<u><em>A is the correct answer.</em></u>
For the second question, we know that condensation causes clouds -- and that neither evaporation nor water vapor would clear clouds to make more of them, which eliminates choices B and D. Going back to condensation, the accumulation of water vapor plays a big role in the formation of clouds. While evaporation does play a part in [it] as well, condensation is what caused the sudden appearance of clouds in the troposphere.
<u><em>C is the correct answer.</em></u>

Answer:
The correct answer is option B.
Explanation:
On seeing the question, it is clear that it is based upon the concept of semi-conservative theory for the replication of DNA. It is mentioned that when the bacteria were grown on N-15, the mass was 55 fg. Now, after two generations, the DNA would comprise N-14 and the mass of them will be 5.4 fg.
The average mass would be = 5.4 + 5.5 / 2 = 10.9 / 2 = 5.45 fg. The mass of the bacteria isolated from the culture would possibly contain both the masses. That is, the mass of DNA with N-14 only would be 5.4 fg, and the mass of DNA with both N-15 and N-14 would be the average, that is, 5.45 fg.
