B. The anterior fontanel.
C. The posterior fontanel.
D. lateral fontanels.

Answer:
1,35 * 10 ^ -2 M
Explanation:
Recuerde que pH = -log [H ^ +]
Sea la concentración de iones de hidrógeno [H ^ +]
Si es así, entonces;
-pH = log [H ^ +]
Por lo tanto;
[H ^ +] = Antilog (-pH)
[H ^ +] = Antilog (-1,87)
[H ^ +] = 1,35 * 10 ^ -2 M
