The watershed divide of the Ural Mountains forms the natural land boundary between the continents of Europe and Asia. The range, averaging 3,000â4,000 ft. in height, extends about 1,640 miles north-south from the Arctic Ocean to the northern steppe of Kazakhstan.he watershed divide of the Ural Mountains forms the natural land boundary between the continents of Europe and Asia.

Yeasts. Yeasts are unicellular fungi. Examples: 1  Saccharomyces cerevisiae â bakerâs or brewerâs yeast. 2  Saccharomyces boulardii is a part of normal intestinal flora; available in pharmacies as probiotic, which can prevent antibiotic associated diarrhea.
The vegetative hyphae obtain nutrients; the reproductive part of the fungus consists of reproductive or aerial hyphae. Yeasts are unicellular fungi. To reproduce, fission yeasts divide symmetrically, whereas budding yeasts divide asymmetrically. Buds that do not separate from the mother cell form pseudohyphae.olds and fleshy fungi consist of long filaments of cells joined together (hyphae). A fungal thallus (body) is the vegetative, nonreproductive part of the organism and consists of a tangled mass of hyphae called a mycelium.
