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

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.
