2. Jessie studies seaweed and she usually takes large amounts of samples. She would take
these samples from only one place and bring them back to the laboratory to run tests.
(a) Based on this information, predict what would occur if there were many separate teams
of scientists just like Jessie, who focused on the same area to collect seaweed samples.
(b) What alternative would you suggest to Jessie in order to avoid disturbing the stability of
the system in the place she collects her samples?

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
