With decomposition, the final deposition of particles(sediments) usually occurs at the mouth of a stream. Then a process called horizontal sorting occurs where the sediments that were once carried down are arranged from big to small. Decomposition in streams takes time so the speed of the water and wind should not affect it nor should gravity or the direction. Streams cannot change direction either unless human involement occurs

Answer:
H+
Explanation:
Hemoglobin is the major protein of red blood cells. It has many exposed amino groups and carboxylic groups at its surface. These NH3 and COOH groups serve as weak acids and bases respectively and allow hemoglobin to serve as a buffer to maintain the pH of the RBC cytoplasm.
As the exposed amino groups of hemoglobin protein bind to the H+ ions, the free H+ concentration of the cytoplasm of RBC is reduced leading to a buffer action to maintain the pH.
