Answer:
One could be in the cell. The cell respires, thus producing carbon dioxide in it. So the concentration builds up in the cell. Diffusion is the net movement of particles from a region of high concentration to a region of low concentration, and the carbon dioxide concentration outside the cell is less, therefore the carbon dioxide molecules moves outs of the cell.
Another scenario is when perfume is sprayed into the air. The perfume particles collides with the air particles (lower or no concentration of perfume). This process goes on and on. This is diffusion since the concentration perfume particles collides with the less concentrated particles of perfume.

The use of retroviral therapies can increase the patient's risk of developing cancer because they may integrate recombinant DNA into the genome in ways that may misregulate the expression of genes. Therefore the correct option is D. 
 
<h3>What is retroviral therapy? </h3>
 
Retroviral therapy is an HIV treatment where medicines are taken as prescribed by a healthcare professional. This treatment reduces the amount of HIV in an HIV-infected person. 
HIV does not have a cure but antiretroviral therapy can reduce the risk of potential health issues caused by HIV. 
This treatment can help to control the virus in an HIV-infected person within 6 months. The treatment for HIV cannot prevent the transmission of other sexually transmitted diseases. 
 
Therefore the correct option is D.
