This exchange process takes place in the aveolus (air sac) inside your lungs by diffusion.
it's from a different concentration gradient
the deoxygenated blood with carbon dioxide diffuse into a aveoli (which is in high concentration) and the aveoli release the oxygen into the blood stream (which is low concentration) therefore the blood will be oxygenated again
I think the answer is..... C.....
Answer:
add 2 electrons
Explanation:
Add 2 electrons to carbide atom make it neutral because there are two unpaired electrons present in the carbide atom and it has -2 charge. So the carbide required two electrons for pairing and make the carbide atom neutral. for adding two electrons its all unpaired electrons paired to other two electrons which complete its valency and make it a stable atom.
<em>All cells have these four parts in common: a plasma membrane, cytoplasm, ribosomes, and DNA. But the main common feature that is most talked about it Cytoplasm and Ribosomes. Cytoplasm, the rest of the material of the cell within the plasma membrane, excluding the nucleoid region or nucleus, that consists of a fluid portion called the cytosol and the organelles and other particles suspended in it. Ribosomes, the organelles on which protein synthesis takes place.</em>
