Algae Blooms
Explanation:
Algae bloom is a rapid accumulation proteins and amino acids that creates the generation of algae in freshwater or marine water ecosystem as a result the discoloration of the water takes place.

There are some questions as to how Galileo proved his claims and theory about the pendulum and its properties which even drove some of the modern people to say that he was just acclaiming false assertions. Of course, Galileo had shared his ideas to his colleagues and might have been documented that he failed to demonstrate it mechanically. Though it is uncertain that he might have not attempted it, if he were to attempt such demonstration, then he might have gone to do the usual model for pendulums which is the tying of a heavy object to the other end and attaching the other end on a high place which would then suspend the heavy object mid-air. This is in connection that Galileo "tried it" with lead and cork.
