The right answer for the question that is being asked and shown above is that: "b. Archaeopteryx fossils share traits with both birds and reptiles." Scientists claim this is evidence of a common ancestor. <span>Archaeopteryx fossils show that the animal had feathers like a bird.</span>
Carbon is found in the non-living part of the hydrosphere, atmosphere, and Geo-sphere, as carbonate (CaCO3) rocks and dead organic matter, such as humus in soil.
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:
false
Explanation:
a microscope is used to enhance small objects like cells.
Neurons function to process and transmit information. In vertebrate animals, neurons are the core components of the brain, spinal cord, and peripheral nerves.
