Which biome, typical of Africa, is home to many grazing animals?
Varvara68 [4.7K]
The Savanna or Savannah

The Savanna is a biome that is typically found in Africa and is characterized by a tree density low enough to allow sunlight to reach the ground and allow for smaller plants such as grasses to grow. The growth of these grasses provides an optimal food source for herbivores, which is why large grazing herbivores such as zebras are found here. The presence of these herbivores allows for the existence of larger carnivores such as lions.

Which of the following molecules does NOT contain a B-1,4 glycosidic linkage?
Lesechka [4]

Answer:

Chitin, Cellulose and Peptidoglycan (B, C and D)

Explanation:

Both chitin and cellulose are composed mainly of glucides, bound by glycosidic bonds of the Beta 1-4 type. This is largely why they cannot be digested by most non-herbivorous animals.

As for peptidoglycans, it is a net. It is a molecular framework present in bacteria that has β1-4 and α1-4 bonds in different proportions.
