Why do you think the worms treated with 1 ml of bleach have a longer reaction time ?

The reaction time of worms depend on the the number of hydrogen (H) ions present in the solution. More the number of hydrogen ions, the worms are more active. Therefore, reaction depends on the type of bleach. in hydrogen peroxide, the reaction time will be less and in other bleach there will be longer reaction time.

the answer is c.) there is a warm front in region a and a stationary front in region b.
