Aspergillus is a member of the Deuteromycetes fungi, which is a group with no known sexual state. With DNA evidence forthcoming, all members of the genus Aspergillus likely are closely related and should be considered members of the Ascomycota.Members of the genus possess the ability to grow where a high osmotic concentration (high sugar, salt, etc.) exists.spergillosis is the group of diseases caused by Aspergillus. The most common subtype among paranasal sinus infections associated with aspergillosis is A. fumigatus. The symptoms include fever, cough, chest pain, or breathlessness, which also occur in many other illnesses, so diagnosis can be difficult.
Polar Bear. Common Names: Sea Bear. Genus: Ursus. Species: maritimus. Polar bears can be found all through the polar regions of the Northern hemisphere. They are the largest carnivore on land. They have a black nose and eyes. They have two layers of fur which is so warm that adult bears can easily overheat when they run.
Distribution and population status The polar bear is a circumpolar species and is found in arctic regions where there is access to sea ice throughout much of the year. Polar bear populations are found in Canada, Alaska (USA), Greenland, the Russian Arctic, the Norwegian Arctic and on the ice surrounding the North Pole.ts longer predatory teeth and sharper molars have helped polar bears adapt to the arctic climate and its almost exclusively carnivorous lifestyle. The polar bear is the youngest species of bear and is closely related to the brown bear (Ursus arctos) and grizzly bear (Ursus arctos horribilis).
