C) the internal pressure is greater than atmospheric pressure.
D) the compliance of the lung decreases.
E) the lungs recoil.
Answer:
(B) the internal pressure is less than atmospheric pressure.
Explanation:
The process of respiration is divided into two distinct phases, inspiration (inhalation) and expiration (exhalation). During inspiration, the diaphragm contracts and pulls downward while the muscles between the ribs contract and pull upward. This increases the size of the thoracic cavity and decreases the pressure inside. As a result, air rushes in and fills the lungs.
Hence, as the thoracic cavity increases in volume the lungs are pulled from all sides to expand, causing a drop in the pressure (a partial vacuum) within the lung itself. As such the internal pressure is less than atmospheric pressure.
During expiration, diaphragm contracts inferiorly and thoracic muscles pull the chest wall outwardly (the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases). As a result, the lungs contract and air is forced out.
During inhalation, air continues to move into the lungs until the internal pressure is the same is atmospheric pressure. Correct option is A.
During inhalation (inspiration), the diaphragm and other respiratory muscles contract, expanding the thoracic cavity. This expansion increases the volume of the lungs, leading to a decrease in the internal pressure within the lungs. As a result, the air from the surrounding atmosphere (which has higher pressure) flows into the lungs, filling them with fresh oxygen. Inhalation continues until the internal pressure in the lungs equals the atmospheric pressure, at which point the flow of air stops, and the lungs are filled with the appropriate amount of air for that particular breath. This process is essential for proper gas exchange, where oxygen is taken into the bloodstream and carbon dioxide is expelled from the body during exhalation (expiration).

C. NADH,ATP, and pyruvate
B. The shells will enrich the compost as an additional organic supplement
C. The shells will have no effect for better or worse
D. The shells will kill the microfauna in the compost heap
Crushed eggshells, when added to a compost heap, serve as an organic supplement, enriching the compost by contributing key nutrients, particularly calcium, vital for plant health.
The addition of crushed eggshells to a compost heap will have a positive effect, making answer B the correct response. Crushed eggshells enrich the compost as they break down, adding valuable nutrients, specifically calcium, to the mix. Calcium is also an important nutrient for plant growth, so the shells can provide additional benefits when the compost is used in the garden. The eggshells are a form of organic supplement that enhance the quality of the compost, making it more effective when used as a soil additive. They will not harm the microfauna in the compost heap; in fact, they can provide grit for their digestive systems.
