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

The answer is A) emulsified by bile salts

<span>In order for the fat to be digested, the fat globules must be emulsified first by bile salts in the stomach.  By emulsifying we mean the breaking of globules of fat into much smaller emulsion droplets. The liver produces the bile salts which breakdowns fats into small droplets. The fat then is digested by lipase. </span>

Could producers survive without consumers? explain why or why not
arlik [135]
Producers could not survive without consumers. Produces rely on consumers to purchase their product, if no one buy their product, then the producer has no money to even produce anything. This like a car, the car is the producer, and the gas is the consumer, the car will not work unless there is gas. So a producer will not survive without the consumer.
