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.
While the majority of amoebozoan species are unicellular, the group also includes several varieties of slime molds, which have a macroscopic, multicellular stage of life during which individual amoeboid cells aggregate to produce spores.Amoebozoa vary greatly in size.ost phylogenetic trees identify it as the sister group to Opisthokonta, another major clade which contains both Fungi and Animals as well as some 300 species of unicellular protists. Amoebozoa and Opisthokonta are sometimes grouped together in a high-level taxon, variously named Unikonta, Amorphea or Opimoda.
