Question

11 hemoglobin is:
a. a protein
b. responsible for binding with oxygen
c. found in leukocytes
d. a and b
e. all of the above
12 which of these is the largest component of plasma
a. ions
b. vitamins
c. proteins
d. hormones
e. water
13 platelets:
a. transport o2
b. form clots
c. transport co2
d. a and b
e. all above
14 red cell counts of 4 million per ml
a. anemic
b. normal
c. danger of clotting
d. leukemia
15 proteins
a. 7% of blood
b. 8% of plasma
c. 55% of plasma
d. found only in hemoglobin

Explanation:

1. Hemoglobin is a protein in red - blood cells responsible for binding with oxygen. It is not found in leukocytes.
2. Water is the largest component of plasma, making up a significant proportion.
3. Platelets are involved in blood clotting. They do not transport oxygen or carbon - dioxide.
4. A normal red - cell count for an adult is typically 4.5 - 5.5 million per microliter. A count of 4 million per ml is slightly low but not necessarily anemic. However, among the options, anemic is the most appropriate.
5. Proteins make up about 7% of blood and about 8% of plasma.

Answer:

1. d. A and B
2. e. Water
3. b. Form clots
4. a. Anemic
5. a. 7% of blood
