(C) both cure and prevent disease among entire population of animals.
Sponges absent
Cnidarians not jointed (Aquatic organisms, all have tentacles with nematocysts - stinging cells, used to capture food.)
Roundworms absent (AKA nematodes are unsegmented, colorless and do not have appendages).
Annelids not jointed (With the exception of leeches, all annelids have chitonous hair-like structures projecting from their cuticle. These appendages fulfill different functions in different species.)
Mollusks not jointed (Invertebrates that lack hard appendages such as legs or antennae)
Arthropods jointed (the arthropods are the only invertebrates to have jointed appendages)
Echinoderms not jointed (Due to their radial symmetry, all echinoderms have appendages which point outward from the center of the body like the spokes on a wheel.)
and vertebrate jointed

<h3>What is beneficial traits?</h3>
- Beneficial traits are extremely varied and may contain anything from protective coloration to the ability to operate a new food source, to a change in size or constitution that might be useful in a certain environment.
- Over time, these favorable traits become more common in the residents. Through this process of natural preference, favorable characteristics are transmitted through generations. Natural preference can lead to speciation, where one species gives rise to a new and distinctly different species.
- The artificial section is the identification by humans of seductive traits in factories and animals, and the steps taken to enhance and memorialize those traits in future years.
