Nitrogen is special because it is necessary for growth and reproduction. It's needed for plants and animals to survive. The main function for the atmosphere i believe is to give oxygen and nitrogen.
Answer:
The correct answer is : oxygen
Explanation:
- Oxygen is carried in the blood by two means:
- 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).
- 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.
