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:
Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens.
Explanation:
The correct order would be:
1. A tree absorbs the carbon from the atmosphere into its leaves for photosynthesis;
2. A caterpillar gets the carbon by eating the tree's leaves.
3. A bird gets the carbon by eating the caterpillar.
4. The bird flies into a building and dies instantly. It falls to the ground.
5. The bird decomposes and the carbon returns to the atmosphere.
The carbon cycle is very similar to the water cycle, though it has its own unique ways. Once the carbon is released into the atmosphere, it will either be absorbed by the vegetation, or go up into the higher parts of the atmosphere. If it is absorbed by the vegetation, the organisms that eat the vegetation will get it in them. When the predators eat those organism they get the carbon into their organisms. When the predators die, they start to decompose. When they decompose, the carbon is released from them and it returns to the atmosphere, and the whole process goes all over again.
