<u>ANSWER:</u>
Diffusion is used by bacteria to transfer antibiotic resistance genes to other cells.
<u>EXPLANATION:</u>
- When bacteria becomes resistant to antibodies, it loses the ability to be inhibited.
- Diffusion in such case is used by bacteria to transfer the antibiotic genes to another species. This is because bacteria has the ability to replicate and transfer resistance by engulfing DNA from neighboring cells.
- Bacteria has the ability to take naked DNA encoding from similar species for the purpose of resistance and diffusion is the process that makes it possible.
