different from animal cells are chloroplasts and cell walls. The answer
is B.
Weathering breaks it down, erosion takes it away
Out of the following given choices;
Select one:
a. hydrogen ions
b. carbonic acid
c. carbonic anhydrase
d. water
The answer is C. carbonic anhydrase is found in red blood
cells and is used to catalyze the forward
and reverse reactions of H2O + CO2 ---à H2CO3 in tissues and
lungs. However, in the plasma, this
reaction is spontaneous in the presence of
water and carbon dioxide (but slower to
that of RBC). It is important in the regulation of pH of blood. The carbonic acid dissociates into H3 + and - HCO3 ions and back to carbonic acid in an equilibrated
and balanced reaction.
