A chemical reaction is a process by which atoms or groups of atoms in a particular substance are rearranged from the arrangement within the reactants to a new arrangement within the products.
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).

Hydroponics way of growing, is way of farming, in which plants are grown in nutrient rich water. So, in Hydroponic growing of sprouts, sprouts get their nutrients from the nutrients supply like liquid fertilizers which are mixed with the water. It is one of the advantage of hydroponic means of growing because, unlike in soil system, the plants root does not have to work hard to get nutrient from underground. The easy availability of nutrients and other condition like water, pH level etc makes plants grow faster are fuller.
Also, advancement of technology have made it possible to prepare built-in hybrid hydroponic system which have multiple ways of delivering nutrient to specific plants.
