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).

Innate behaviors are behaviors that do not need to be taught, you naturally develop them. Some examples are eating and sleeping.
The four learned behaviors: Habituation, Sensitization, Imprinting, and <span>The Conditioned Response.
</span><u>Habituation </u>- Turtle hides into shell after being touched. After being touched several times and has associated that no danger is involved, turtle is no longer scared.
<u>Sensitization</u><u /> - Your first presentation may make you insanely nervous, but once you gain more experience you become less and less nervous.
<u>Imprinting</u><u /> - Ducklings following their mother
<u>Conditioned Response</u><u /> - Dogs don't like getting shots. They may associate the scent or appearance of the animal hospital with getting shots. They may try to avoid the scent or something similar to the hospital.
