Homeostasis
The condition in which an organism's internal environment is kept stable in spite of changes in the external environment.
Adaptation
An inherited behavior or physical characteristics that help it organism survive and reproduce in its environment.
Vertebrate
The bones that make up the backbone of the organism. In humans, or the 26 bones of make up that bone.
Invertebrates
An animal without a backbone.
Tissue
A group of similar cells that perform specific functions.
Organ
Good body structure that is composed of different kinds of tissues that work together.
Radial symmetry
Hey body plan in which any number of imaginary lines that pass through a central point divide the animal into two mirror images.
Bilateral symmetry
Body plan in which a single imaginary line divides the body into left and right sides that are mirror images of each other.
Cnidarian
A radially symmetrical in vertebrae that uses stinging cells to capture food and defend itself.
Mollusk
And invertebrae with a soft unsegmented body most are protected by a hard outer shell.
Arthropod
And invertebrae that has external skeleton, the segmented body, and jointed appendenges.
Exoskeleton
An external skeleton; a tough, waterproof outer covering that protects, supports, and helps prophetic about ration of water from the body of many invertebrates.
Echinoderm
A radially symmetrical marine invertebrate that has internal skeleton and a system of fluid filled tube's.
Endoskeleton
And internal skeleton, structural support system within the body of an animal.
