Final answer:
The correct answer is B) Squirrel.
Step-by-step explanation:
The correct answer is B) Squirrel.
Squirrels are multicellular organisms made up of many cells, each of which is specialized to perform a distinct function. For example, the cells in a squirrel's heart are specialized for pumping blood, while the cells in its muscles are specialized for movement.
This is in contrast to the other options: Paramecium, Amoeba, and E.coli. Paramecium and Amoeba are single-celled organisms, while E.coli is a bacterium. These organisms do not have specialized cells like a squirrel does.
