Answer:
Higher
Explanation:
Molecules such as oxygen move from a higher concentration to a lower concentration across a semi-permeable membrane. This process is called simple diffusion.
Therefore, for oxygen to leave the alveoli and enter the blood, there would need to be a higher concentration of oxygen inside the alveoli and a lower concentration of oxygen in the blood.

Body parts of unrelated organisms that serve the same function are examples of convergent evolution.
<span>Convergent evolution is the phenomenon when the different species independently create similar features. Those features can be structures that have similar form or function. This happens because organisms have been adapted to similar environments or ecological niches.</span>
