Bear habitats are generally forests, though some species can be found in grassland and savana regions, and the polar bear lives in arctic and aquatic habitats. Most bears are 1.2–2 m (4–7 ft) long, plus a 3–20 cm (1–8 in) tail, though the polar bear is 2.2–2.44 m (7–8 ft) long, and some subspecies of brown bear can be up to 2.8 m (9 ...
This means the species a binomial name refers to can be clearly identified, as compared to the common names of species which are usually different in every language. [6] However, establishing that two names actually refer to the same species and then determining which has priority can sometimes be difficult, particularly if the species was ...
A cyclic ether and high-boiling solvent (b.p. 101.1 °C). Tetrahydrofuran (THF) A cyclic ether, one of the most polar simple ethers that is used as a solvent. Anisole (methoxybenzene) An aryl ether and a major constituent of the essential oil of anise seed. Crown ethers: Cyclic polyethers that are used as phase transfer catalysts. Polyethylene ...
The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed.The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb).
The ulna is estimated to have been 48.5 cm (19 in) long when complete- for comparison, modern subadult polar bear ulnae are 36–43 cm (14–17 in) long. [1] The ulna was dated to the early Weichselian of the Late Pleistocene (~70kya). [2] Of the 16 specimens identified as Pleistocene polar bears, this is the only fossil ascribed to this ...
Acceptable alternative names for some of the parent hydrides are water rather than oxidane and ammonia rather than azane. In these cases the base name is intended to be used for substituted derivatives. This section of the recommendations covers the naming of compounds containing rings and chains.
Articles relating to the polar bear (Ursus maritimus), a hypercarnivorous species of bear.Its native range lies largely within the Arctic Circle, encompassing the Arctic Ocean and its surrounding seas and landmasses, which includes the northernmost regions of North America and Eurasia.
A carbon–oxygen bond is a polar covalent bond between atoms of carbon and oxygen. [1] [2] [3]: 16–22 Carbon–oxygen bonds are found in many inorganic compounds such as carbon oxides and oxohalides, carbonates and metal carbonyls, [4] and in organic compounds such as alcohols, ethers, and carbonyl compounds.
