Guar gum is more soluble than locust bean gum and is a better stabilizer, as it has more galactose branch points. Unlike locust bean gum, it is not self-gelling. However, either borax or calcium can cross-link guar gum, causing it to gel. In water, it is nonionic and hydrocolloidal.
How long is a mother polar bear pregnant for? The exact/accurate gestation period is not known but it is around 8 months. Each litter has 2 cubs and sometimes even 3. Cubs weigh around 10 to 15 kilograms (22 to 33 pounds)â¦ at birth. Cubs stay with the mother for around 2 to 3 years of their life and then go away.
Female black bears may give birth to 1 to 6 cubs (twins are most common) in January or February. Black bear cubs may be 1/250th the size of the mother bear, and are the smallest newborns, compared to their mothers, of any placental mammal. These tiny and blind cubs remain in the den with the mother and continue to grow and develop in what is described as an âexternal pregnancyâ until it is time to leave the den in the spring.
