hold - Definitions from Dictionary.com
Student or Learner
Some frogs naturally freeze solid in winter, then thaw and hop away in the spring ... Scientists believe these frogs hold the secret for safer organ transplants.
Does "hold" mean "have" and "own?"
Second, could I say "hold the secret of" instead? Thanks.
What the scientists believe is not that frogs have some knowledge that they can pass on [as some 'life coaches' might claim "I know the secret to a happier you"]. What they believe is that there is something about the structure of a frog (a combination of a natural anti-freeze constituent in the blood and a metabolism that suits the transition from inanimate to animate) that can be used in designing a safer procedure for organ transplants.
Thanks, Soup and Bobk.
