Answer:
As DNA contain phosphorus in its structure in large amount, therefore, Harshey and Chase labeled DNA with radioactive phosphorus and because protein contains some amino acids which have sulfur so they labeled T2 bacteriophage protein with sulfur.
So after that they infected E.coli bacteria with radioactively labeled phages and after centrifugation, they have found that pellet which contains cells is showing the presence of radioactive phosphorus and supernatant which have T2 phage capsid protein showing the presence of radioactive sulfur.
Therefore by labeling viral protein and viral DNA they found that DNA is the genetic material not protein.
To substances that are bonded together but can be taken apart
Answer: Cohesion
Explanation:
The cohesive attraction or cohesive forces is the action or property of like molecules which stick together.
It can be intrinsic forces that can be caused by the structure and shape of water. This allows the water molecules to stick to each other.
Due to this phenomenon of water it has a spherical shape and it flows in a liner motion.
Hence, the force that is present between two water molecules is cohesion.
Answer:
This type of brain plasticity is known as neuroplasticity.
Explanation:
Neuroplasticity allows neurons to regenerate (anatomically and functionally), which allows them to form synaptic connections. Neural plasticity means the ability of the brain to recover and restructure. This is a characteristic of the adaptive potential of the nervous system allowing the brain to recover from disorders, and can also reduce the negative effects of diseases such as multiple sclerosis, Parkinson's, Alzheimer's disease, etc.
