Explanation;
-Valence is the number of electrons lost or gained to complete an element's outer energy level.
-When an atom gains or loses a valence electron, it forms an ion. Atoms form ions in order to help another to obtain a full octet and to stabilize the valence.
-Some atoms gain or lose electrons to form ions because they need to become more stable. They sometimes give them to have an outer shell or gain them to get a closer charge to eight.
<u>Answer:</u>
The pathophysiology instructor will emphasize that the cells of the proximal tubule have a fine, villous structure that increases surface area, allowing for active transport processes to occur with fluids.
<u>Explanation:</u>
- The proximal tubule is a part of the nephron and it controls the "pH of the filtrate" by exchanging "hydrogen ions for bicarbonates".
- It also secretes organic acids like creatinine and bases to be mixed with the filtrate, so that it is neutralized.
- Thus it helps in the transportation of the filtrate and is also responsible for absorption and re-absorption of the fluids.
