Most of the oxygen transported by the blood
a. bound to a plasma protein.
b. carried by white blood cells.
c. bound to hemoglobin.
d. dissolved in plasma.
e. in ionic form as solute in the plasma.

c. Bound to hemoglobin.

Explanation:

The oxygen is relatively insoluble in plasma. At normal atmospheric pressure, only 0,3% of oxygen dissolves. That why there are respiratory pigments that elevate almost 70 times the capacity to transport O₂ of blood. The most common respiratory pigments are hemoglobin (in all vertebrates and some invertebrates) and hemocyanin (in mollusks and arthropods).

they are c. hope this !

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
