Answer:
Option C, Intrapleural pressure is less than intrapulmonary pressure
Explanation:
During inspiration, the air enters the lungs due to lower pressure in the intrapulmonary or intra-alveolar than the atmospheric pressure. During quite respiration, the intrapulmonary pressure reduces to a pressure that is 3 mm Hg lower than that of atmospheric pressure. During quiet expiration, the intrapulmonary pressure rises up to a pressure that is 3 mm Hg higher than that of atmospheric pressure. This leads to lack of air in the intrapleural space thereby producing intrapleural pressure which is lesser than that of intrapulmonary pressure.
This difference in pressure (i.e higher pressure with in the lungs than the atmosphere) causes lungs to remain attached to the chest wall and hence looks inflated.
Hence, option C is correct
Answer:
The removal of soil will increase the rate of erosion and the flattening of the mountain will change the direction in which water flows off of the mountain.
Answer:
The researcher centred on the potential uses of biochar, charcoal primarily used for agricultural and to improve the quality of post mining sites.
A method called mountaintop removal was used by mining firms. This means that they remove rock and mineral deposits off the top of the mountain to gain access to within the coal seams. The resulting soil is infertile and strongly acidic.
The compacted soil after mine proves harder to bring seed into the soil.
The researchers try to use biochar to help reforest the soil at the post-mining site. Before it was reseeded and replanted, they got permission to add a layer of biochar to a post-mining site. the team created
“planting cells” of biochar‐enhanced soil on the post‐mining site and that showed improvment in the sapling growth.

Explanation:
The bacterial capsule is a well-organized layer of material lying outside the bacterial cell wall serving to protect the bacteria and which is not easily washed off.
<h3>What is the bacterial capsule?</h3>
The bacterial capsule is a well-organized layer of material lying outside the bacterial cell wall and which is not easily washed off.
The bacterial capsule is a layer of polysaccharides which are found outside the cell envelope, therefore, it is regarded as being part of the outer envelope of a bacterial cell.
The bacterial capsule is associated with being the cause of various bacterial diseases.
