A stored form of carbohydrate in animals' muscle and liver is glycogen.
Glycogen is a polysaccharide (starch) made of repeating units of glucoses bonded together.

B) cells or tissue that produce light
Explanation:
It wouldn't be A because photophores do not affect the color of other organisms.
It wouldn't be C because the cells produce light, they don't necessarily change color.
Lastly, it wouldn't be D because it isn't a whole organism producing the light, it's an organ. Organs are multiple tissues working together, and tissues are groups of cells.
A controlled variable is not changed throughout an experiment. It is there so that the other variables being tested on can be better understood.
