Kisachek [45]

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.

There are multiple lines of evidence that provide support for common ancestry and evolution. Write 3-4 paragraphs describing at
Colt1911 [192]

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.

What can show how life has changed on Earth?
Ksivusya [100]
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.
