Yes, a tree is falling over in a forest make a sound because both the tree and ground are hard surfaces which can produces sound by contact physically with each other. For testing this hypothesis, we have to take a tree and cut that tree. when the tree falls on the ground it will definitely produces sounds by contact physically with the ground when falls with a large force.
Answer:
The correct answer is A. Tobacco mosaic virus
Explanation:
Virus can have DNA and RNA as its genetic material. Tobacco mosaic virus has RNA as its genetic material. Protein is not a genetic material because it is a product coded by genetic material.
So a hybrid can be made only when the genetic material of two different organisms is mixed not two different biomolecules. Therefore when RNA from the tobacco mosaic virus is mixed with the protein from a DNA virus the result would be a tobacco mosaic virus only.
