-(â)-lactic acid or (R)-lactic acid. A mixture of the two in equal amounts is called. -lactic acid. Lactic acid is hygroscopic. -lactic acid is miscible with water and with ethanol above its melting point which is around 17 or 18 Â°C. -lactic acid and. -lactic acid have a higher melting point. In animals, -lactate is constantly produced from pyruvate via the enzyme lactate dehydrogenase (LDH) in a process of fermentation during normal metabolism and exercise.
25 Wolves Chase Down Bison: One Of The Largest Wolf Packs Ever Filmed. This video is the first of its kind. A pack of northern gray wolves â at 25 members strong, one of the largest wolf packs ever filmed â chases down a herd of wood bison, the largest land animals in North America. This scene from the upcoming Frozen Planet series was filmed in Wood Buffalo National Park in Canadaâs Northwest Territories at the height of the Arctic winter.
The dire wolf averaged about 1.5 m (4.9 ft) in length and weighed between 50 and 79 kg (110 and 174 lb), which made it the largest species in the genus Canis. Limb elements are rarely found outside the La Brea Tar Pits, which makes it hard to compare the size of average individuals between populations.nlike the gray wolf, which is of Eurasian origin, the dire wolf evolved on the North American continent, along with the coyote. The dire wolf co-existed with the gray wolf in North America for about 100,000 years.
