Explanation:
Protists = eukaryotic organisms tgat are mostly classfies as unicellular/ mostly seperate nuclear division phases of mitosis doesnt occur
for now we know that it is not d (bacteria) or a (too board)
c and b show describe a word called 'cell specialisation'
i think the answer is c since it is said to be mostly unicellular and we know that single cell doesnt have much specilaised cell
idk

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).
