Answer:
Hydrogen ion(H+)
Explanation
The human blood has carbonic acid and bicarbonate anion as buffer to maintain the blood pH between 7.35 and 7.45. A virtual value higher than 7.8 and 6.8 can lead to death.
Taking coffee which has a low pH will lower the pH of the blood. In order to raise the pH back to normal and lower the level of acid present in the system. The human buffering system will to take up Hydrogen ion.
Answer: C. 82.26%
Explanation:
Given : The red blood cell counts of women are normally distributed with


Let X be the random variable that represents the red blood cell counts of randomly selected woman.
Z-score : 
For X=4.2

For X=5.4

Now, the probability that the women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter will be :-

Hence, 82.26% of women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter.
