Cold water currents flow from the poles to the equator
Explanation:
A is the right answer, because when forming ice cubes the water molecules get much more organized and structured than before.
so, the entropy decreases.
in all the other options things get more distributed, so the entropy increases.
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>
ITS B because the temp changes so it becomes cold
Africa is at the disadvantage of having droughts given that it is located in a very tropical zone. Additionally, Africa is subjected to tropical cyclones, earthquakes and locust infestation.
