Rasek [7]
<span>Answer: continually increasing pressure on the unaffected lung.

In tension pneumothorax, the pressure is so high that it will push surrounding organ like another lung, heart, or blood vessels. Pushing another lung can make it less expandable, so less air can come inside and less oxygen can be gained.
Pushing heart and blood vessels can also disturb blood circulation.</span>

Anna71 [15]

Answer:

chloroplasts and mitochondria.

Explanation:

Chloroplasts and mitochondria are the organelles capable of ATP production by photophosphorylation and oxidative phosphorylation respectively. Chloroplasts are the site for photosynthesis. The light reactions of photosynthesis include splitting of the water molecule in presence of sunlight and transfer of electrons from PS-II to PS-I via electron carrier. During electron transport, a proton gradient is created which in turn drives ATP synthesis.  

Mitochondria are the site for aerobic stages of cellular respiration. Glycolysis and Kreb's cycle, the first and second stages of cellular respiration produce NADH and FADH2 during the redox reactions. These reducing powers are oxidized by giving their electrons to the terminal electron acceptor, the oxygen molecule.

Electrons from the reducing powers are carried to oxygen molecules via a series of electron carrier proteins embedded in the inner mitochondrial membrane. During electron transport, an electrochemical gradient is created which in turn drives the ATP synthesis.

Vladimir79 [104]
Tissues form when many similar specializes cells come together.

The level of complexity in organisms from smaller to larger are:
Cells, tissue, organ, organ system, and organism finally.

Cells makes up tissue, tissue makes up organ, organs makes up organ systems, and organ systems makes up an organism.

Therefore, if the same type of cells come together, they'll make up tissue.
