2.movement of hco3 from plasma to rbc

Answers:
1- Latency
2- 70% ethanol
3- Sterlization
4- Its the anterior part of palate. My guess wud be incisive papilla.
5-Chromafin cells in adrenal medulla( not cortex) and dorsal root ganglia in symathetic sysytem
6-- 2X10-6
7-- Donno. But my guess wud be 1.
8-- Movement of hco3 from rbc to plasma to be converted to co2 that diffuses out of lungs.

Good luck
