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
pill they take can help or ease the pain they have even if no active ingredient
is present.
Therefore, the effect is more
than positive thinking or believing that a treatment will work by creating a
stronger connection between the brain and body as they work together.

Though I cannot write this essay for you, I can provide some information to get you started on the relationship between ancestry and evolution.
<h3 /><h3>How are ancestry and evolution related?</h3>
Ancestry and evolution share a close relationship in that we can use one to learn about the other. Evolution can be <u>traced </u>using ancestry. By analyzing the genetic information of ancestral species and using information gathered about the environment in which they lived, we can deduce the impact of evolution on said species. One possible example is that penguins used to be capable of flight, but given their mostly aquatic environments, have evolved wings more suited for swimming, and lost the ability to fly as a result.
Therefore, we can say that ancestry and genetic information can be used to support the theory of evolution by examining how two species can be very different but share a common ancestor, and evolution can explain these changes.

As you increase exercise and muscle activity, your heart rates increases. That is one feedback mechanism. Your heart delivers oxygen and nutrients to your muscle and other parts of the body quicker.
Climate change, habitat destruction, extinctions — thousands of years ago. And humans may have been partly to blame for many of those changes in nature, too. with a changing climate, led to the extinction of many species of megafauna about 12,000 years ago in the southern portion of what is now South America.
