Answer:
Change in food source.
Explanation:
If there is a change in food source, then the organism will have to adapt to that change. For example, with Darwin's Theory on the finches on the Galapagos Islands. There were many different varieties from different size to different beaks. This was because of changes on food sources and they adapted to obtain them more.
These proteins are called enzymes. They are very shape specific and therefore will usually lower the activation energy for a specific reaction.

The thorax is a very vital and important organ in the human body.
- It is a structure that serves as a<u> </u><u>protective covering</u> for organs in the body such as<u> the lungs, the heart, some vital blood vessels</u> e.t.c
It is<u> false</u> that to <em>make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.</em>
- When a person breathes in, <u>the chest cavity expands (the volume increases) and the pressure in the thorax decreases.</u>
- When a person breathes out, <u>the chest cavity decreases in size, and the pressure in the thorax increases. </u>
- Therefore, we can see that the <u>process of breathing in humans</u>, follows the <u>principle of Boyle's Law.</u>
- Boyle's law states that as the<u> volume increases there is a decrease in pressure</u> and <u>as the volume decrease there is an increase in pressure. </u>
Therefore, It is <u>false</u> that to <em>make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.</em>
