Document Summary
Cancer cell change extracellular matrix ---> cancer cells travel in your body. Most animals have nervous tissue & muscle tissue. Cnidarian: invertebrate ocean animal that has tentacles surrounding the mouth, e. g. sea anemones, corals, and jellyfish. Planarian: small flatworm that lives mainly in freshwater, is not a parasite, and has a three-branched intestine. Arthropod: a type of animal that has jointed legs, a body divided into several parts, and a skeleton on the outside. Animals have common features of early development: blastula & gastrula. Blastula: embryo at an early stage of development, consisting of a hollow ball of cells. Gastrula: stage in embryonic development after the blastula during which the embryo develops two layers. Dominant stage: juvenile stage(not mature yet) what we find in all animals. Hox genes: regulate other genes important for morphology and pattern formation.
