The answer is B: All of the carbon dioxide in the blood forms carbaminohemoglobin.

Explanation for each option:

A. Most of the carbon dioxide is converted to the bicarbonate ion \(\mathrm{HCO}_{3}^{-}\).

  • This statement is true. The majority of carbon dioxide in the blood is transported in the form of bicarbonate ions. This conversion occurs in red blood cells and is facilitated by the enzyme carbonic anhydrase.

B. All of the carbon dioxide in the blood forms carbaminohemoglobin.

  • This statement is false. While some carbon dioxide binds to hemoglobin to form carbaminohemoglobin, it is not the primary form of carbon dioxide transport. Only a small portion of carbon dioxide is transported this way.

C. Almost all the oxygen is transported by the hemoglobin in the red blood cells.

  • This statement is true. The vast majority of oxygen in the blood is bound to hemoglobin within red blood cells, allowing efficient transport to tissues.

D. A very small amount of \(\mathrm{O}_{2}\) is dissolved in plasma.

  • This statement is true. Only a small fraction of oxygen is dissolved directly in the plasma; most is carried by hemoglobin.

In summary, option B is the false statement regarding the transport of oxygen and carbon dioxide in the blood.

Chapter 15: "What Is Freedom?": Reconstruction, 1865-1877 15.3. What were the social and political effects of Radical Reconstruction in the South? Match the descriptions of white Republicans in the South during Reconstruction to the correct term. These northern whites relocated to the South after the Civil War. Southern whites believed they had come simply for economic gain. These southern whites supported the Republicans and had not supported secession or the Confederacy. These were wartime Unionists from the South who hoped Reconstruction governments would help them recover from wartime economic losses. Some were investors in land and railroads who saw the postwar South as an opportunity to combine personal financial gain with a role in helping to substitute "the civilization of freedom for that of slavery."
