Answer: Placebo effect
John is experiencing placebo
effect where the pill that contains no pain killing medication has given pain
relief to John. A placebo is a substance with no therapeutic effect but sometimes
improves patient’s condition. This is due to patient’s expectation that the

The frequent rate of mutation in viruses such as HIV would make them more successful in avoiding the immune system.
<h3>What are mutations?</h3>
Mutations are random changes which occur in the sequence of nucleotides in the DNA of an organism.
Mutations produce deleterious effects when they occur in organism. However, in some instances, mutation produce advantages to the organism in which they occur, for example to make pathogens resistant to drugs.
This is because the drug target site has been modified. Also, the immune system will be unable to recognize the pathogen as in the case of viruses such as HIV.
In conclusion, mutations in pathogens can help them to evade destruction by the body's immune system or drugs.
