A sample contains four separate unicellular organisms plus one isolated muscle cell from a multicellular animal. Enter how many cells belong to the unicellular organisms.
Richtige Antwort
4
Erklärung
The answer is 4 because each of the four unicellular organisms consists of one cell. Counting the isolated muscle cell would give 5, but that cell is only part of a multicellular animal and is not itself one of the unicellular organisms.
