Sexually
Monogamously
You discover an organism. Upon examination, you discover that it is multicellular and autotrophic. It is composed of cells that have nuclei and cell walls. The organism reproduces sexually. You determine that the organism belongs to either the kingdom Plantae or Animalla. Which piece of evidence will you now use to identify the correct kingdom?
The organism reproduces sexually
The organism contains cells that have nuclei and cell walls.
The organism is multicellular
All piece of evidence place the organism in the kingdom Animalla

The organism shown is in the Animal Kingdom of the genus Alligator. Why would this organism be listed in the Eukarya Domain?
Its cells have not nuclear membrane and are found in extremem conditions
Its cells have no nuclear membrane and are found in all living organisms
Its cells have a nuclear membrane and are found in all living organisms
This organism would not be classified under this domain
What is the best explanation for classifying the six kingdoms into three domains?
