Answer 1

  They are both adjectives meaning "possible to detect", "discernible", "readily observed". As far as I am aware, the two words can be used interchangably, that is, one can be used instead of the other.

Examples:

  We monitored the patient's heartbeat for a 24-hour long period of time. No sign of  malfunction of the heart was detectable during monitoring.

  The patient's blood tests yielded a detectible, albeit minute, variation in the level of lithium compounds.
