COVERAGE OF BIOLOGICAL ISSUES BASED ON THE HARDY-WEINBERG LAW
Akhmedova Mastura Makhmudovna
Abstract: The Hardy-Weinberg law is a law describing the distribution of the meeting rate of alleles and genotypic classes in freely interbreeding populations that differ in alleles of a single gene, and today it is often used in biological matters. In this article, Hardy-Weinberg examines the essence of the law

ORGANIZING TEACHING DEMONSTRATIVE EXPERIMENTS AND LABORATORY EXERCISES BASED ON PHYSICAL EQUIPMENT
Israilov Shermurad Shamsiddin ugli
Abstract: Improving the effectiveness of physics teaching is an urgent problem of today. An approach to assessing the acquisition of new physical knowledge, which is a system of criteria levels, where the transition to each subsequent level can be made only if the previous one is available. A method of teaching experimental activity to physics students based on the implementation of the system-activity approach with the help of a school physical experiment is offered. The main thing is the activity of methodology students in mastering not only the content, but also the process of acquiring new knowledge
RESEARCH ON THE BIOLOGICAL EFFECTIVENESS OF WOOD CONSTRUCTION MATERIALS TREATED WITH OLIGOMERIC ANTIPYRENE-ANTISEPTICS WHICH CONTAIN SULFUR
Furqat Nazarov, Fayzulla Nurkulov, Abdulahat Djalilov
Abstract: The purpose of researching the biological effectiveness of oligomer antipyrene-antiseptics, which contain sulfur, is to protect wood materials from termites. Termites cause serious damage to the wooden part of buildings and structures because of eating wood materials. In this research work, oligomer composites, which are biologically effective in combating termites, obtained physic-chemically. The biological effectiveness of the samples obtained researched in accordance with the requirements of GOST

Abstract: In the article, it is fully explained that the activity of catalase, protease, peroxidase enzymes in the soil under the influence of green microalgae can increase soil fertility in irrigated meadow alluvial soil.
DETERMINATION OF BIOLOGICAL ACTIVITY OF CYNARA SCOLYMUS L. ROOT EXTRACT AGAINST HARMFUL MICROORGANISMS IN THE TERRITORY OF UZBEKISTAN
Kh.Kh. Dolimov, I.J. Jalolov, M.Y.Imomova, M.R.Mamadaliyev
Abstract: The biologic activity of extracts obtained from the leaves of Cynara scolymus L., belonging to the Asteraceae family, using ethyl alcohol and low polar solvents, was investigated against Gram-positive bacteria (Staphylococcus aureus ATCC 25923 and Bacillus subtilis RKMUz-5), Gram-negative bacteria (Pseudomonas aeruginosa ATCC 27879 and Escherichia coli RKMUz-221), and yeast (Candida albicans RKMUz-247). As a result of the research, it was found that extracts obtained using ethyl alcohol exhibited high activity against Gram-positive bacteria
