Users may be unwilling to add configuration safeguards because configuration seems too difficult or users are reluctant to spend the time with advanced configuration settings. Unfortunately, the default configuration of most home routers offers little security and leaves home networks vulnerable to attack. Small businesses and organizations often use these same home routers to connect to the Internet without implementing additional security precautions and expose their organizations to attack. Why secure your home router? Home routers are directly accessible from the Internet, are easily discoverable, are usually continuously powered-on, and are frequently vulnerable because of their default configuration. These characteristics offer an intruder the perfect target to obtain a userâs personal or business data.
The urchin's mouth is located on its underside and its digestive tract ends with the anus located at the top of the sea urchin, relative to the mouth. Similarly to a starfish, the urchin uses the tube feet on its underside to direct food towards the mouth.
In fishes the gills are located in gill chambers at the rear of the mouth (pharynx). Water is taken in through the mouth, is forced through openings called gill slits, and then passes through the gill clefts, spaces between the ranks of delicate gills, bathing them continuously.n the process of animal evolution, gills first appear in annelid worms, in the form of simple, pectinate, or bipinnate plates and simple or branched filaments. They are located on the lateral motor appendages (in freely moving forms) or at the head end of the body (in those living in tubes).
