Answer:

C. But see the answer under C. Apparently C is the accepted answer.

Explanation:

A. Not A.I don't think that's a problem for gulls especially on beaches.

B. Not B.  Their feather do not look like they need much help in keeping their feathers attached when in flight.

C. This is not really the answer, but it is the best answer of these 4. The actual answer is that the bones are porous for better air intake which provides more oxygen and hence they are better able to fly.

D. Not D. Food has nothing to do with the problem. Birds get an adequate amount of food without their wings being porous. See the answer for C.

A group of cells is assayed for DNA content immediately following mitosis and is found to have an average of 8 picograms of DNA
creativ13 [48]

Answer:

16 picograms

Explanation:

According to the given information, the observed cells have 8 picograms of DNA after mitosis. If these cells enter the cell cycle, DNA replication will take place during the S phase of the interphase of the cell cycle. The process of DNA replication would double the DNA content of these cells making it 16 picograms per nucleus.  

The S phase of the interphase is followed by the G2 phase and then prophase during which there is no change in the DNA content of the cells. Hence, each of these cells would have 16 picograms of DNA at the prophase of mitosis.
