1.	hat would have happened ? If....RBCs had mitochondrig
Answer» Since RBC has limited life span and is anucleated, meaning that it does not do much work in the sense of biosysnthesis (replication, transcription and translation etc). No synthesis, no energy required. Major role of RBC is gas transport. And this transport is a simple diffusion that uses concentration gradient in peripheral tissues. That is another evidence for no energy is required to do the major job of RBC. Cellular movement of RBC is very passively done by heart and stream of blood. Therefore, its viability does not go forever unlike other terminally differentiated cells. Not only the nucleus and mitochondria, but also much of the cytoplasmic components are also missing. Some differences found mammals and nucleated animals may have different physiology adapted and evolved in accordance to the environments over long period.
