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:
All electromagnetic fields (EM waves) consist of two component fields, electric fields (E fields) and magnetic fields (H fields). E fields and H fields are companions and together make up the total EM field. Where one is, so is the other

Answer:
B, C, E.
Explanation:
Unsaturated fats are more likely than saturated fats to be liquid at room temperature. (because saturated fats are solid at room temperature and unsaturated fats are liquid at room temperature).
Triacylglycerols (triglycerides) are composed of fatty acid residues and glycerol. (because by the reaction between glycerol and 3 long chain fatty acid triglycerides formation occurs and form 3 ester linkages).
Fats that contain more unsaturated fatty acid residues than saturated fatty acid residues are more likely to be liquid at room temperature. (because saturated fats are solid at room temperature and unsaturated fats are liquid at room temperature).
