[D] 160-180 days
Show Answer
Correct Answer: C [100-120 days]
Notes:
Red blood cells (RBCs) have an average lifespan of 100-120 days and are produced in the bone marrow, while the spleen is where they are broken down. Macrophages break down RBCs into globin and heme, recycling amino acids and iron for various purposes, including protein synthesis. Some parts of old RBCs are reused in creating new ones. The average lifespan of cells in the human body is 7 to 10 years, but it varies across cell types and organs. Neutrophil cells, for example, last about two days.
9. Which process enables the Peepal tree to release oxygen at night?
[A] Crassulacean Acid Metabolism
[B] C3 Photosynthesis
[C] C4 Photosynthesis
[D] Carbon cycle re-balancing
Show Answer
Correct Answer: A [Crassulacean Acid Metabolism]
Notes:
The Peepal tree uses Crassulacean Acid Metabolism (CAM) photosynthesis, allowing CO₂ uptake at night and oxygen release, a trait seen in some succulents and epiphytes to minimize water loss. CAM enables the Peepal to continue gas exchange during the night, unlike typical C3 or C4 plants.
