Abiologist isolates a large, unidentified molecule from some cells in his lab. he determines that the macromolecule breaks into smaller pieces with the concomitant loss of water. what reaction has he observed?

The correct answer is Dehydration reaction.

Dehydratation reaction is a chemical reaction that involves the loss of a water molecule (H2O) from the reacting molecule and it is a subset of condensation reactions. The reverse reaction is the process of hydrolysis.

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.
