The process of pumping oxygen-rich blood out of your heart into the rest of your body is . A. picks up nutrients, water, and waste materials

B. pulmonary circulation

C. the lungs, where it picks up oxygen again

D. capillaries

E. 5

F. systemic circulation

Pulmonary circulation.

Explanation:

The question is asking you to identify a process.  The process is pulmonary circulation.  While your blood certainly transports nutrients, water, and waste materials, that answer simply does not match the structure of the question.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
