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).
As the ocean level rises sea water floods inland and puts a risk to water reserves like dammed lakes and other places by contamination
Answer:
C
Explanation:
the pressure on the inner core is greater than the pressure on the outer core and the melting point of iron, the main constituent of the core, increases as soon as the pressure goes up
