Answer 1

The correct answer is : oxygen

Step-by-step explanation:

• Oxygen is carried in the blood by two means:

1. About 2% of the oxygen is carried in the dissolved form in blood plasma and in the water present in the red blood cells (RBCs).
2. Rest 98% of the oxygen is carried in bound form with the haemoglobin as oxy-haemoglobin inside the RBCs.

• RBCs lack nucleus. This place is occupied by hemoglobin molecules that binds to oxygen and form oxy-hemoglobin.
• This increases the capacity of each RBC so that it can carry more oxygen to all the parts in the body.
