1. cut up 3 potato pieces. cut the pieces so that they are different sizes. 2. put food coloring in each cup, and then place one potato piece in each cup. 3. after a few minutes, take the potato pieces out and cut them in half. 4. observe how far the food coloring penetrated the potato pieces, and determine how that relates to surface area and volume. in the lab, what do the potato pieces represent? what does the food coloring represent?

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
