Answer:
Photosynthetic organisms was the reason of these atmospheric changes.
Explanation:
The plant which is discovered by the scientists that is apparently devoid of life but has ice caps located at the poles which reveals that planet's atmospheric O₂ levels sharply increased about 1,000,000 years ago was due to evolution of photosynthetic organisms like cyanobacteria etc which went extinct and then O₂ levels dropped quickly 50,000 years ago. So photosynthetic organisms was the reason of these atmospheric changes.
Divergent boundaries are formed when plates are pulling apart; this kind of force is called tension. The opposite boundary is a convergent boundary, where two plates collide; this happens near subduction zones. The force present in a transform boundary is shearing, which is when two things grind past each other.
Answer= convergent=shearing
Hemoglobin is involved in the transport of other gases: It carries some of the body's respiratory carbon dioxide<span> (about 20–25% of the total</span><span>) as </span>carbaminohemoglobin<span>, in which </span><span>CO2</span><span> is bound to the globin protein. The molecule also carries the important regulatory molecule </span>nitric oxide<span> bound to a globin protein </span>thiol<span> group, releasing it at the same time as oxygen.</span>
