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.
Segmented worms (Annelida) are a group of invertebrates that includes about 12,000 species of earthworms, ragworms and leeches. Segmented worms live in marine habitats such as the intertidal zone and near hydrothermal vents.egmented worms are divided into the following taxonomic groups: 1  Polychates-The polychaetes include about 12,000 species that are characterized by having multiple hairs on each segment. 2  They have nuchal organs on their neck that function as chemosensory organs.
