s2008m [1.1K]

The options attached to the above question are given below:

A) The boys at first were very polite about my medals and asked me what I had done to get them.

B) I showed them the papers which were written in very beautiful language of full of fratellanza and abnegazione but which really said with the adjectives removed that I had been given the medals because I was an American.

C) after that their manner change a little toward me although I was their friend against Outsiders

D) I was afraid but I was never really one of them after they had read the citation because it had been different with them and they had done very different things to get their medals.

E) I had been wounded it was true but we all knew being wounded after all was really an accident.

ANSWER

The correct option is D.

In the statement given in option D, it can be seen that the speaker was formerly a soldier, who had fought in a war and had been awarded a medal to that effect. But despite knowing about this meritorious service that he had rendered to his country and the award he was given, he was not really accepted as an inner person by the group of people that was refereed to in the statement. They did not think much of him.

You decide to repeat the Meselson-Stahl experiment, except this time you plan to grow the cells on light 14N medium for many gen
Effectus [21]

Answer:

One band of light density and one band of heavy density.

Explanation:

According to conservative model of replication, the original strands do not separate from each other during replication. Hence, after replication the old strands are together and the new strands are together.

Here, cells were grown in 14N medium first so 14N was used for DNA replication and all DNA molecules had 14N. When the cells were transferred to 15N medium, only 15N was available for replication process. New DNA molecules would be synthesised using 15N (15N15N) and old DNA molecules have 14N (14N14N). Hence, in density gradient one band will be of light density (14N14N) and one band will be of heavy density (15N15N).
