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.

Answer:
I think the answer is coal
These alveoli are the smallest types of lung tissue, and one of the most important. In addition to being the primary means by which oxygen enters and carbon dioxide escapes the bloodstream, these small pouches of air are also the reason why the lungs do not totally collapse when a person breathes out. This is because they contain a cell that secretes a special chemical to lower the surface temperature to prevent lung collapse. The alveoli also contain other cells that secrete chemicals to attack and remove any foreign objects in the lungs, such as dust, dirt and other debris.
In addition to making up alveolar sacs, alveoli also form alveolar ducts. It is estimated that there are more than 300 million alveoli in the human lungs, all of which are located in either alveolar ducts or sacs that are found at the end of the smaller passageways, or bronchioles, in the lungs.
SHORT ANSWER:
Alveolar sacs contain tiny pouches called alveoli, whose primary function is gas diffusion. These clusters of alveoli have thin walls that allow oxygen to pass easily from the lungs into the bloodstream and carbon dioxide to flow from the blood to the lungs so it can exit the body.
The pentose sugar on RNA is called ribose. (a trick to remember it is that the "R" in RNA stands for ribo)
