The diaphragm in the diagram below is a muscle that contracts during inhalation. thus option A is correct option.
<h3>What is the role of the diaphragm?</h3>
The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily.
Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges.

Answer: e.Woman; there is not enough information to tell if the nondisjunction happened in meiosis I or II.
Explanation: There is not enough information to tell if the nondisjunction happened in meiosis I or II. Nondisjunction can occur during meiosis I and meiosis II, resulting in abnormal chromosomes number of gametes. The important difference between nondisjunction in meiosis 1 and Ii is that during meiosis 1, homologous chromosomes fail to separate while in meiosis II, sister chromatids fail to separate meaning it could have happened in meiosis I or II but we were not given.
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>
