This depends on the amount of the starfish's body that need to be regenerated. If it is just the tip of an arm, it would take a matter of weeks. If one arm is regenerating the rest of its body, it can take quite a few months.
about 14-20 years
Wings on most birds can take up to about four - five months to grow back enough to be of concern.
Algae can grow back in as soon as 5 hrs.
maybe about a month or two (scales grow slowly)
A very long time.
Yes. The long tail feather often drop off during the first molt when all the roosters feathers are replaced by new one's. The new long feathers will take more time to regrow so be patient, they will come back. Many roosters lose the long feathers due to picking from the hens while they roost at night
The starfish will regenerate another arm. The arm that was lost does not grow into another starfish.
How long it takes a little bit of alopecia to grow back varies depending on the person. It can take days to weeks to grow back.
