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
you are right what is the question
Answer:
Movement of particles from a region of high concentration to a region of low concentration
Explanation:
- Diffusion can be defined as the movement of particles from a region of high concentration to a region of low concentration.
- Diffusion is a special type of diffusion that involves movement of solute molecules from a region of a high concentration to a region of high concentration until equilibrium is achieved.
- Diffusion is a passive transport of particles, which means it does not involve use of energy in the form of ATP like the case of active transport.
The answer for the question above is the last option. The evidence from <span>the Arctic that shows the ocean has a significant influence on climate change is that, ice </span><span>reflects heat from the sun and open water absorbs it. Hope this answers your question. Have a great day!</span>
<span>The correct answer is B. During transcritption, RNA polymerase synthesizes a complementary RNA transcript, from the DNA. RNA lacks thymine, and possess uracil instead of it. The RNA polymerase makes this antiarallel primary transcript, complementary to the DNA</span>
