Explanation:
When there are low oxygen levels in blood, the blood pH tends to lower. This is because there is an increased level of carbon dioxide in the blood that is converted to carbonic acid by carbonic anhydrase. When carbon acid dissociates, into H⁺ and HCO₃⁻ . The H⁺ influences the increase in acidity of the blood. The kidneys will excrete most of the H⁺ and retain most of the HCO₃⁻ to help maintain the right blood pH. However, most of blood pH homeostasis is maintained largely by the lungs.

Answer:
The true statement is: "Spring tides are the highest, while neap tides are the lowest."
Explanation:
- The range of difference in the level of water between high and low tide is always larger in spring tide.
- Neap tides are the moderate tides. It does not have huge difference in higher and low tides because the bulging of the ocean ( by the sun) balances the bulge of the ocean caused by the moon.
- This balance is not found in spring tides that is the main reason for spring tides to have the highest level for both higher and lower tides.
