Abstract
The article presents the results of the influence of the developed musical model with optimized physical exercises from modern fitness areas (yoga, Pilates, aerobics, taibo, functional training, etc.) on the student's body. We studied 45 children of school age. The objectives of the study were: to find the relationship between musical rhythm and heart rate; to identify the physiological "response" to the morning motor stimulus embedded in a specific musical model. The heart rate was recorded using the Polar sports technology in Finland. The study established the relationship between musical rhythm (bpm) and heart rate, as well as optimized physical exercises that are adequately superimposed on the musical model.

Introduction
An important component of a person's health-improving activity is morning exercise [1, p. 314]. The situation around this event is diverse in all countries. In Australia, this is a block of stretching exercises to music, residents of European countries perform highly intensive" blocks " of strength exercises, in the United States-this is a minimal-simple set of exercises without additional load [4, p. 5684].
The ARTEK international Children's Center (hereinafter referred to as "ARTEK") is a research site and an object of Federal significance. There are nine camps on the territory of the center, and in each of them the morning begins with physical activity to music. Employees of the Artek sports center note that morning exercises do not have a single structure and stage [2, p.166]. To date, the physical education instructor chooses the musical accompaniment, motor actions and the rhythm of their performance to his "taste", guided only by General guidelines. All this makes it difficult for students to repeat and remember.
The absence of a single model of morning exercise that takes into account the speed of music playback (bpm), optimization of physical exercises from modern fitness programs and the physiological response of the body of schoolchildren predetermined our study.
Organization and methods of research
During the two summer camps, we surveyed 45 students (average age 14.9 years, average weight 50.2 kg, average height 165.8 cm). A musical model of a certain rhythm (BPM) is proposed, equipped with physical exercises from modern fitness programs (yoga, Pilates, tai-Bo, functional training). This model was memorized and presented by the physical education and sports teacher to students every morning. The study of the functioning of the circulatory system during
morning physical activity was carried out using sports equipment from Polar, Finland. The heart rate (hereinafter referred to as heart rate) was recorded. The results of statistical analysis are presented in the form of arithmetic mean and standard deviation (M±q). According to the student's criterion, the sample was examined for belonging to the normal distribution law. Indicators where P>0.05 were considered significant. The analysis was performed in the Microsoft Exel 2017 statistical package.
Research result
Performing physical exercises is accompanied by an increase in the level of metabolic processes in the human body. The circulatory system is the most accessible for evaluating an urgent response to a motor stimulus. Heart rate is the oldest biomarker of quantitative "measure" of functional state [3, p. 47]. The connection of the physiological parameter with the speed of musical accompaniment (bpm) is traced (tab. 1). The reliable average value of the maximum heart rate was 127.7 beats per minute, which corresponds to a musical rhythm of 128 (bpm). These data indicate the performance of morning motor activity in a zone of low (aerobic) intensity [5, c. 1147]. The average heart rate values of individual blocks report the highest energy expenditure, which falls on the fourth block (tai-bo). This block is represented by dynamic Boxing hand movements and jumps. The decrease in motor activity occurs gradually, through marching steps, stretching and breathing from the block (yoga) at a musical rhythm of 124 (bpm). The physiological response of the cardiovascular system at this stage of morning activity reveals a decrease in heart rate to 100.6 beats per minute. We believe that these heart rate values are acceptable and do not cause significant functional changes in the body.

A graph was constructed based on the average group monitoring data (Fig. 1). It is worth noting that with an increase in the musical rhythm (bpm), the heart rate increases gradually, as indicated by the General linear trend. Also, we believe that the increasing trend in (Fig. 1) it is explained by the features of selected physical exercises from modern fitness areas (Pilates, yoga,
functional training, taibo, etc.) and performing them with certain muscle modes to music. However, it should be taken into account that the established patterns were also influenced by such factors (incentives) as climatic, psychological, social and similar loads to which the child's body successfully adapted.

The measurements revealed the sequence of fitness directions, the time frame for each motor exercise, the optimal model of musical rhythm (bpm), and pulse values for each stage of morning exercise (Fig.2).

Thus, a certain musical model and optimized motor activity is expressed in an adequate physiological response and repeatability of students.
Conclusions
The results of our research allow us to draw the following conclusions:
1. The undulation of the physiological response of the cardiovascular system fully duplicates the musical model embedded in the structure of morning exercise
2. Reproduction and visualization of the music model, as well as optimization of physical exercises from modern fitness areas developed in the course of the study contributes to improving the quality of the health process in the children's camp

Abstract
Results of the cytological analysis of a meiosis metaphase I at a full series of monosomal lines of soft spring wheat variety Milturum 553 are presented in this article. On the basis of the conducted researches it was established that conjugation of chromosomes has the polygenic control system where entering genes stimulators and inhibitors, genes with autonomous functional activity and genes with the interfaced action type. Existence of the genes having identical efficiency in double and one doses is revealed. Besides, reasons for variation from control were determined for the analyzed traits of sisterly disomik.

В данной статье представлены результаты цитологического анализа метафазы I мейоза у полной серии моносомных линий сорта яровой мягкой пшеницы Мильтурум 553. На основании проведенных исследований установлено, что конъюгация хромосом имеет полигенную систему контроля, куда входят гены стимуляторы и ингибиторы, гены с автономной функциональной активностью и гены с сопряженным типом действия. Выявлено наличие генов, обладающих одинаковой эффективностью в двойной и одной дозах. Кроме того, были определены причины отклонения от контроля по анализируемым признакам сестринских дисомиков.

Мягкая пшеница Triticum aestivum Ь. является аллогексаплоидом и включает в себя три генома: А, В, Б, принадлежащим разным видам родов Triticum Aegilops [1-3]. В состав каждого генома входит по 7 хромосом (2п = 14). На основании проведенного нуллисомно-тетрасомного анализа было установлено, что по три пары хромосом, принадлежащим
разным геномам, обладают сходным содержанием генетической информации и являются гомеологами [4]. После этого каждая хромосома получила двойное обозначение, где цифра указывает на принадлежность ее к конкретной гомелогичной группе, а буква - к геному. В результате такой нумерации каждая из 7 гомеологичных групп включает по три
