Annelids are characterized by the presence of a segmented body, with each segment containing a repeated set of organs and structures. Other key features of annelids include:
Body Cavity:Annelids have a true coelom, or body cavity, which provides space for internal organs and allows for greater complexity in body structure.
Hydrostatic Skeleton: Many annelids have a hydrostatic skeleton, which consists of fluid-filled compartments that provide support and enable movement.
Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles or energy stored in fields.
