<span>The option which is not a potential concern associated with the use of biotechnology is the production yields of GM foods, whereas the other options are quite dangerous when you think about them. Genetic ownership means that somebody could steal your genes and use them for cloning, which is another option here. Trainsgenic foods also have to be kept safe, so as to stop someone from messing with them. The production yields of GM foods is not the problem, the problem is whether that food is healthy or not.</span>
        
             
        
        
        
Diffusion occurs because of the movement of molecules from
the region of higher concentration to the region of lower concentration. This
movement of molecules occurs due to a thermal motion. Diffusion normally occurs
between two compartments having difference in concentration. In case of fluid
it moves from the region of higher concentration to the region of concentration
until a balance is reached. The process of diffusion is very important for the
humans as well. The oxygen that humans breathe in gets diffused with the blood.
