More astonishing than the difference between the length of the lists of Old World's and New World's domesticated animals is the difference between the lengths of the lists of infectious diseases native to the two.
Fetal Hemoglobin Test. Definition. Fetal hemoglobin (Hemoglobin F), Alkali-resistant hemoglobin, HBF (or Hb F), is the major hemoglobin component in the bloodstream of the fetus. After birth, it decreases rapidly until only traces are found in normal children and adults. Purpose.
Alkalinity is the water's capacity to resist changes in pH that would make the water more acidic. It should not be confused with basicity which is an absolute measurement on the pH scale.) Alkalinity is the strength of a buffer solution, which is composed of a weak acid and its conjugate base. It is measured in meq/L (milliequivalents per liter). Measuring alkalinity is important in determining a stream's ability to neutralize acidic pollution from rainfall or wastewater.
