Question

Imagine that biologists have discovered a new organism. It was found in a pond in
Pennsylvania. Using microscopes, biologists have determined that the cells of this organism
have no nucleus. Use the dichotomous key to identify the domain for this organism. Circle
your choices to determine the correct domain.
Dichotomous key to domains
1 a cells lack a nucleus surrounded by a membrane – go to 2
1 b cells contain a nucleus surrounded by a membrane – Eukarya
2 a found in many of earth’s typical environments – Bacteria
2 b found mostly in extreme environments – Archaea
