The answer should be the respiratory system.
When we breathe, air is taken in our body and they travels to the lungs through the trachea. The lungs is the site where the oxygen from the air we just breathed is exchanged with the carbon dioxide (waste).
In the lungs, there's something call air sac, which diffuses the oxygen to the capillaries. At the same time, carbon dioxide from the capillaries diffuses back to the air sac. Then, we breathe out and the carbon dioxide and the remaining substances in the air that we don't need is breathe out.
That explains why there's more oxygen in the unbreathed air than oxygen from breathed air, and less carbon dioxide in unbreathed air than breathed air.
And after that, the capillaries transfer these oxygenated blood to the pulmonary vein, and then transfer them back to the heart.
I think it’s lateral and medial but I’m not sure
idk about 10, i can't see the diagram
11. The moment magnitude scale is one of many seismic magnitude scales used to measure the size of earthquakes." The scale was developed in the 1970s to succeed the 1930s-era Richter magnitude scale.
use that ^
The correct answer is a eukaryote. While it would be an impulse to answer prokaryote since the first thing that will come to our minds if we deal with a microorganism that thrives in extreme environments (i.e. hot thermal vents) will be archea, which are prokaryotes. But in this case, it is clearly specified that the single-celled organism has a nucleus which is the characteristic feature of eukaryotes.
Bacteria is incorrect as bacteria are prokaryotes. Plant is incorrect as all plants are multicellular organisms.
<span>Both pine trees and ferns have the ability to make their own food via photosynthesis. They are both able to convert water and carbon dioxide into oxygen and sugars. Based on the concept of domains they are both classified under Eukaryota. </span>
