<h2>Required Answer :- </h2>

The exchange of gases takes place in the <u>alveoli.</u>

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

<h3>Additional information :- </h3>

  • Alveoli are microscopic air sacs.

  • They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.

  • Atmospheric air contains little CO2, but blood flowing in pulmonary capillaries has a higher concentration of CO2.

  • CO2 diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.

  • Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.

  • Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.

Hope it's helps !!

<h3> Answer</h3>

alveoli

<h2> Explanation</h2>

During gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Q? Describe the concentration gradient of carbon dioxide across the cell membrane.
hoa [83]

Answer:

Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.

Explanation:

CO_{2} undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.

Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.

Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.

What a vestigial structure? How does it support evolution?
atroni [7]
A vestigial structure is a structure that kind-of just "hangs out" in our bodies. We don't really need it, yet it is there. So, why is it there??? We probably needed it, for example, when we needed to digest plants. (Appendix) Some say that the appendix was used for digesting plants and berries, but it is really just speculation. We "evolved" to not need the appendix. 
Here are some other vestigial examples: wisdom teeth, tail bone, pelvic bone in a snake, and wings on a flightless bird. 
I hope this helped, if it did not let me know!!
I hope you have a fantastical day!!!XD
