Clue: This type of organism can be anywhere from the size of my fist to 3
times as large as I am. They can walk or run. They have either 2 or 4 legs
and have to hunt for their food. I observed its cells under the microscope.
Each of the cells had a very large, darkened circle inside of it as well as
other small structures that had lines around them.
What kingdom does this organism belong to? Explain. Pleas help
