. Then write a paragraph where you assume that all the peas in the pod had the same genes for size. In a brief discussion below, describe how the environment within the pea pod has affected development of the peas in the essay box. Where are the smallest peas located in the pod? Where are the largest peas located? What is the average diameter of the peas? (add all the diameters of the peas and divide by the number of peas.) Is there a gradual change in diameter of the peas, or are they mostly the same, except for a few?

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
