Answer:
it is c: Taking observations at precise intervals
Explanation: I just took the test.
The ER comes in two different morphological forms: smooth ER and rough ER
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>

<h2>
Answer</h2>
Tertiary Consumers get least amount of the energy.
<h2>
Explanation</h2>
In an ecological pyramid less energy is available to organisms in the upper level because each organism releases some of the chemical energy as food and to the air as thermal energy .Therefore primary consumers get almost 10% of autotrophs prduced energy. The second consumers in the pyramid get 1% from primary consumer. In the case of tertiary consumers, they get only 0.1%. Hence the top consumer of a food pyramid receives the least energy.
