Answer:
an organism is multicellular, heterotrophic (cannot make its own energy), and has no cell wall, it is an animal. This is the definition of the kingdom Animalia.
There are unicellular animal-like members of the kingdom Protista commonly called protozoa.
Fungi are heterotrophic and multicellular, but they have a cell wall made of chitin.

Explanation:
The cell membrane consists primarily of a thin layer of phospholipids which spontaneously arrange so that the hydrophobic "tail" regions are shielded from the surrounding polar fluid, causing the more hydrophilic "head" regions to associate with the cytosolic and extracellular faces of the resulting bilayer. This forms a continuous, spherical lipid bilayer approximately 7 nm thick, barely discernible with a transmission electron microscope.
The arrangement of hydrophilic and hydrophobic heads of the lipid bilayer prevent polar solutes (e.g. amino acids, nucleic acids, carbohydrates, proteins, and ions) from diffusing across the membrane, but generally allows for the passive diffusion of hydrophobic molecules. This affords the cell the ability to control the movement of these substances via transmembrane protein complexes such as pores and gates.
Cephalization is the differentiation of end part of the body into a head in which nerve tissue is concentrated. Sponges have a very loose nervous system and their cells work individually, not controlled by a nervous system. Since they have no defined head as a consequence of concentrated nervous system, the sponges could not have cephalization either.
My answer would be "Earthquakes happen along cracks in the earth's surface, called fault lines, and can be felt over large areas"
