There are seven main levels of classification, divided into five kingdoms.
Animal - Animals are multicellular eukaryotes whose cells are bound together by collagen.
Plant - Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae.
Fungi - A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.
Protist - A protist is any eukaryotic organism that is not an animal, plant, or fungus.
Monera (unicellular) - Kingdom Monera belongs to the prokaryote family. These are the oldest known microorganisms on earth.

The mitochondrion helps to maintain homeostasis in the cell by b. extracting energy from food for the cell.
The answer should be a cnidarian, because it has a gut. Sponges do not have guts. They, however, have hollow central cavity, but a cnidarian also has a central cavity (gastrovascular cavity) that is, again, hollow.
Both animals arr invertebrates and live in shallow salt water.
She should look for a nucleus and other membrane-bound organelles to determine if the cell is eukaryotic or prokaryotic. The eukaryotic cell will have a nucleus and membrane-bound organelles, while a prokaryotic cell will not.
They breathe through their skin. Air dissolves on the mucus of their skin, so they MUST stay moist to breathe. If worms dry out, they suffocate. As fresh air is taken in through the skin, oxygen is drawn into the worm's circulatory system, and the worm's hearts pump the oxygenated blood to the head area.
