flattened shapes. This allows oxygen and nutrients to pass through their bodies by diffusion. The digestive cavity has only one opening for both ingestion and removal of wastes. These features are distinct for this phylum but they still have three main cell layers namely endoderm, mesoder...
The moray eel (Gymnothorax javanicus) has a very cool evolutionary adaptation in its already-terrifying teeth. Its small body is full of muscle, which helps it wind through the waters with ease. It's known for showing off its razor-sharp teeth while it swims, but this isn't aggressive; i...
Name the major classes in the eight most diverse phyla of invertebrate animals and list their distinguishing characteristics. What are three types of homology? In which of the following groups would you find metanephridia and nephrostomes? (a) annelids (b) flatworms (c) nematodes (d) ...
Despite the relation of FAs levels with the consumption of some food groups, there is limited knowledge on the possible association of whole dietary patterns with blood/tissue FA profiles. Moreover, there is apparently no comparative data on the levels of main FAs in blood/tissue across different...
The oldest major environmental impact was due to mining activity in the surrounding mountains of Cartagena-La Unión, which began with the first Phoenician colonies about 3500 years ago, and developed under Carthaginian and Roman rule, mainly with the exploitation of copper (Cu), tin (Sn), zinc...
