Biology FAQ

A highlight of few questions (some answered, some not :))

1. How a drug (say ingested) makes it to its target within the body?
2. How many different types of cells are in the body?
   For that we almost have to define what "different" means. To give you an example, in the case of a human, are you the same when running than when sleeping? Anyhow, scientists are trying to answer that which is work in progress. Check this Human body cells FAQ.
3. How we go from a single cell to all the cells that form the body? How transitions can be so sharp (think of a wall of an organ, of a blood vessel, the surface of the eye)?
4. Do all cells keep splitting in two in the human body, for instance, skin cells, to replenish the dead ones, or actually only certain ones within a tissue?
5. Why we age?
6. How is memory stored in the brain?
7. How life was created?
8. How it evolved into such complex organisms?
