Here is a diagram to better visualize the problem. My homework question asks to find the temperature at point c. I have already calculated that n=0.41 and that the pressure at point b is 2.01966 atm. You do not need to solve for c, just please tell me how. Okay so I couldn't handle it anymore and I just looked at the answer which happened to be 810J. This make me even more confused.
The annelid worms owe their evolutionary success to segmentation. The coelom becomes divided into a linear series of identical fluid-filled compartments, or segments, that run between the head and the anus. The 8,600 species of annelid worms take their name from the Latin anellus, meaning little ring.
The head and the rear of the body is not segmented. The digestive system of species in this phylum runs the length of the body. Food is taken in at one end of the body and expelled at the other end. Annelids have two sets of muscles that help them move.here are about 15,000 species in this phylum. The phylum includes earthworms, leeches, and marine worms known as polychaetes. Species in this phylum have metameric bodies. Metameric bodies are divided into segments called annuli. The annuli are covered in tiny hairs called setae. Setae help the worms move.
