Explanation:
The oldest fossil evidence of seed plants is of Late Devonian age, and they appear to have evolved out of an earlier group known as the progymnosperms. These early seed plants ranged from trees to small, rambling shrubs; like most early progymnosperms, they were woody plants with fern-like foliage.
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.
