<span>The unifying principles of virology are: All viruses are made of a nucleic acid molecule in a protein coat, all viruses are incapable of replicating themselves and must infect a host cell to do so, and all viruses must have genomes that provide mechanisms for them to work.</span>
Answer:
It is in hypotonic case.
Explanation:
The plant cell is in hypotonic case because the the solute concentration outside the cell is lower than in the cell. Plant cell do not burst in hypotonic solution because they have a cellulose cell wall outside its cell membrane. The cell wall is permeable and it's prevent the cell from bursting after it absorb water through osmosis.

Answer:
The temperature of the surrounding air increases when the atmospheric CO2 level increases.
Explanation: Carbondioxide gas is a very important gas in the environment but high amount of it cause damage to the organisms.
Carbondioxide gas is also called greenhouse gas because it has the ability to absorb or trap heat energy when the solar radiation goes into the space after hitting the earth surface. If the concentration of carbondioxide gas is increased, more heat energy will be trapped and thus increase occurs in the temperature of the atmosphere which results in global warming.
