The videos below show a piece of fruit or vegetable immersed in solutions of differing osmolarity.

Once every hour the cells are removed from the solution and placed on a scale.

You can measure the mass each time the fruit or vegetable is removed from the solution

2. Consider the experiment set-up described.
What is the independent variable in this experiment?

-Hint What is the scientist changing or manipulating?

-Change in Mass
-Type of organism
-Time
-Osmolarity of the solution

(a) scientists could collect and combine data on fish populations all around the world to show that their populations are declining. (b) scientists collect and combine data on fish populations all around the world to show that their populations are increasing. (c) scientists work together and use past data to show that fish populations are becoming locally extinct in some areas. (d) scientists work together and use past data to show that some fish populations are adapting to environmental changes.
