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:
<em>Escherichia coli </em>- Facultative anaerobe
<em>Micrococcus luteus </em>- Obligate aerobe
<em>Clostridium sporogenes</em> - Obligate anaerobe
Explanation:
In simple terms, obligate aerobes are organisms that require oxygen to grow and metabolize molecules such as fats and sugars to produce energy. Many animals fall under this category. Other examples are <em>Mycobacterium tuberculosis </em>and <em>Micrococcus luteus</em>.
Facultative anaerobes are organisms (usually bacteria) that can grow both in the presence and absence of oxygen. The most example of this are the <em>Escherichia coli</em><em>.</em>
Obligate anaerobes are organisms (usually microorganisms) that cannot survive when exposed to normal atmospheric concentration of oxygen. Examples are <em>Clostridium sporogenes</em><em> </em>and <em>Clostridium botulinum.</em>
