Answer 1

Answer

16. Option A) Axillary

17. Option B) False

• Neutral pH valve is 7. The valve above 7 is considered alkaline.
• Hence, The pH of blood plasma that is approximately 7.35-7.45, is slightly alkaline.

18. Option C) 2

• pH of gastric acid ranges between 1 and 3.
• Hence, on average the pH of HCl in stomach is 2.

19. Option B) False

• If a solution has more Hydrogen (H+) ions in it, its pH valve is low.
• Hence, the solution considered acidic.

20. Option B) Oxygen

21. Option B) 12 neutrons and 11 protons
