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>

A life expectancy of 2 to 5 years less than peers.
Answer:
Each ion or charged molecule in a fluid contributes to the fluid's overall electric charge. A difference in charge between two regions of fluid can affect the rate and direction of diffusion between them. For example, positively charged substances will tend to diffuse toward a region with an overall negative charge.
Explanation:
Answer: Adenine, Guanine, Thymine or Uracil and Cytosine
Explanation: Nitrogenous bases are one of the major constituents of nucleic acids. They contain nitrogen and act as bases in reactions.
Answer: Summer
Explanation: When the southern hemisphere is closest to the sun, and it receives the most sunlight it is summer time, while in the northern hemisphere it's winter.
The main factor that determines seasons is the way sun rays enter Earth, and not as much proximity, since there is only a 2% variation in the distance overall
