Which of the following statements are true/false?

1. The blood transports carbon dioxide comparatively easily because of its highest solubility.
2. Approximately 8.9% of carbon dioxide is transported being dissolved in the plasma of blood.
3. The carbon dioxide produced by the tissues, diffuses passively into the blood stream and passes into red blood corpuscles and react with water to form H₂CO₃.
4. The oxyhaemoglobin HbO₂ of the erythrocytes is basic.
5. The chloride ions diffuse from plasma into the erythrocytes to maintain ionic balance.

Study the following forms of transport of respiratory gases
A) ${\mathrm{CO}}_2$ as bicarbonates
B) ${\mathrm{O}}_2$ through plasma
C) ${\mathrm{CO}}_2$ as carbamino compounds
D) ${\mathrm{O}}_2$ through $\mathrm{RBC}$
E) ${\mathrm{CO}}_2$ in a dissolved state
Arrange the above in sequence in ascending order based on their percentages.

In the given graph curves $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ represent the relation between partial pressure of oxygen $\left({\mathrm{pO}}_2\right)$ and saturation of haemoglobin with oxygen. If curve $\mathrm{A}$ represents the condition of blood in a regular artery then please select the correct statement from below.

Select the favourable conditions required for the formation of oxyhaemoglobin at the alveoli.
