Course abstract

Study course acquire with biological processes as the basis of agricultural production and environmental protection. Discuss cells and organisms as open systems and their mater and energy metabolism. Regulation of enzymes activity. Biodiversity of microorganisms and their use in biotechnology. Biocoenosis.

Learning outcomes and their assessment
