Hidden Life of the Cell Documentary 2 Why do you believe the adenovirus must invade the nucleus of a cell in order to reproduce itself?
The virus can reproduce on its own but prefers to use the machines of another cell
The virus does not have the machines to read its own DNA and then use the recipe to create copies of itself

Brainless plz) A

The most appropriate answer would be A. The particle is a virus because it does not use energy and cannot reproduce by itself.  

Virus is defined as a small infectious agent that carry its own genetic material (DNA or RNA) but divides only in the living cells of other organisms (bacteria, human, animals, plants etc).

They are acellular in nature and thus are not able to reproduce on their own. They use the metabolism and machinery of the host cell in order to produce and assemble multiple copies of themselves in a cell.

They attach to the specific binding site of their target cells and inject their genetic material into the cell. The host cell's machinery is then used to replicate, transcribe and translate viral genetic material.

The viral genome produced are assembled in the protein cascade. They are then released by causing bursting of the infected cell.

relationships play a major role in a human's emotional and mental wellbeing. healthy relationships with the people around you are even linked to a smaller production of cortisol, a stress hormone.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
