Question

(0) Most of the carbon dioxide is transported in dissolved form in blood while oxygen is carried
by haemoglobin because
(a) Co, is more soluble in water than oxygen and haemoglobin has very high affinity for
oxygen
(b) haemoglobin is unable to carry CO2
(c) O, is more soluble in water than Co, and haemoglobin has high affinity for oxygen
(d) water is unable to carry 0,
(4 X 1 = 4)​

Answer 1

Answer:

"is" (and any subsequent words) was ignored because we limit queries to 32 words.

Carbon monoxide has a greater affinity for hemoglobin than oxygen. Therefore, when carbon monoxide is present, it binds to hemoglobin preferentially over oxygen. As a result, oxygen cannot bind to hemoglobin, so very little oxygen is transported through the body (Figure 1).
