Answer 1

Blood plasma transports oxygen in dissolved state, percentage of which is 3%.

Explanation:

Oxygen is not very soluble in liquids, so only about 3% of it is transported dissolved directly in the blood plasma. The remaining 97% is carried by red blood cells bound to haemoglobin as oxyhemoglobin.
