The statement is true. Atelectasis is the collapse or closure of a lung resulting in reduced or absent gas exchange. It may effect part or all of a lung. An airway blockage also can cause Atelectasis. A blockage may be due to a foreign object, a mucus plug, lung cancer, or a poorly placed breathing tube from a ventilator. When a blockage occurs, the air that's already in the air sacs is absorbed into the bloodstream.
Answer:
Cell X
Explanation:
Prokaryotes do not have a nucleus or any other membrane-bound organelles (including chloroplasts). So cell X is a prokaryote.
Answer:
C, D.
Explanation:
C: The flowing lava creates extra rock. For example, entire islands are formed via this process of volcanos erupting, lava cooling, repeat.
D: Silt from erosion (erosion itself is considered destructive, but the resulting silt can turn into something constructive.) can build up entire mounds or mountains over time.
Answer: d. on the plasma membrane
Explanation: Prokaryotic cells also synthesis ATP the limitations is that enzymes required for the synthesis of ATP are attached to the cell membrane which surrounds the cell. ATP synthesis complex of prokaryotic cells are embedded in the cell membrane. Prokaryotes lack mitochondrial/thylakoid membrane so therefore, ATP is produced on their cell surface membrane.
