Imagine you are in a laboratory. you are exploring
the following reaction: a + b - c
when the product c is created, bubbles form.
when 10ml of a is added to 10ml of b, the
reaction takes twenty seconds. your teacher gives
you three unknown substances (x, y, and z), one
of which is a catalyst for the reaction.
design an experiment to test substances x, y, and
z to determine which one is a catalyst for the
reaction.

ecosystem to a more stable state. this is also classified into two (2) types:

when a previously occupied environment was disturbed that kills much of all its
