-(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.
How large is one packâs territory? Wolf territories usually vary in size from 200 to 500 square miles, but may range from as little as 18 square miles to over 1,000 square miles. Territory size is typically based on the density of preyâmore deer or elk in the territory means the wolves have to travel less to find food. Wolves spend about 35% of their time traveling. They often travel 20 to 30 miles per day, but may cover over 100 miles in a day when prey is scarce. 7.
