1. What happens to organisms that have adaptations that longer work for their environment?

There's two possibilities, either nothing happens, or they are slowly eliminated from the population.

Explanation:

Some adaptations are no longer useful, like wisdom teeth for us humans or hip bones in whales. Whales definitely don't need hip bones, but having them also doesn't really hurt their chances of survival. In these cases it doesn't matter, so the individuals remain in the population.

If the organism's chance of survival is decreased due to its adaptation no longer working, then it will be eliminated from the population through natural selection. For example, if an individual's camouflage stops working, they will be less likely to survive and reproduce.

you must remain stopped until the stop signal is retracted and the red lights are turned off. approaching traffic in the opposite roadway of a divided highway shall not be required to stop, even if the school bus has the stop-arm extended and the alternately flashing warning signal lamps on.
