Oh god so many. First off, because the produce is being modified from its original/natural state, it does not fit in with environment. Meaning you have organisms (plant and animals) that go extinct and what not. Also there are certain chemicals that are not supposed to be present in this produce, and that not only affects people, but those pollutants infect the soil/plants/water/animals. Everything is a system, and when you tamper with it, it goes out of balance. But those are some of the things I can list. Hope it helped
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.
