o blood doping
section 34.3 blooms knowledge
o polycythemia
o infectious mononucleosis
o anemia
o leukemia
1 pts
question 4
if more carbon dioxide than usual is in the blood, the ph of the blood will:
o decrease
o increase
o increase then decrease
o stay the same
1 pts
question 5
wbcs
o are formed in the spleen
o carry o2 in blood
o protect body from microbes
o clot blood

Explanation:

• For Question 3: Anemia is a condition where there are too few erythrocytes (red - blood cells). Blood doping increases red - blood cell count, polycythemia is an excess of red - blood cells, infectious mononucleosis is a viral disease not related to erythrocyte count, and leukemia is a cancer of white - blood cells.
• For Question 4: When more carbon dioxide is in the blood, it forms carbonic acid which dissociates to release hydrogen ions, lowering the pH (making it more acidic).
• For Question 5: White blood cells (WBCs) protect the body from microbes. They are formed in the bone marrow (not just the spleen), red - blood cells carry oxygen, and platelets are involved in blood clotting.

Answer:

Question 3: anemia
Question 4: decrease
Question 5: protect body from microbes
