What is genetic variability?; the difference in the number of individuals; the diversity of genes and alleles in a population; the rate of population growth; the mortality rate; 2
What are alleles?; different forms of the same gene; types of organisms; age categories; parts of the cell membrane; 1
What is a locus?; type of migration; place on the chromosome where the gene is located; number of individuals in the population; part of the ecosystem; 2
Why is the presence of different alleles in the population important?; increases genetic diversity and adaptability; reduces the number of individuals; accelerates mortality; reduces population density; 1
What is a population?; a set of individuals of the same species living in the same space and at the same time; a set of different species; a part of a cell; a set of genes in an individual; 1
What are population processes?; all changes in individuals at the cellular level; all changes within the population over time; only migrations; only birth rates; 2
What is the most important attribute population?; density; abundance; migrations; spatial arrangement; 2
What are semelparous individuals?; individuals that reproduce more than once; individuals that migrate every year; individuals that reproduce only once in their lifetime; individuals that live in groups; 3
What is the size of the population?; number of individuals per unit area; total number of individuals in the population; number of young individuals; number of annual migrations; 2
What is population density?; total number of individuals; birth rate; number of individuals per unit area or volume; speed of species expansion; 3
Why is it important to determine the population density?; to determine the color of the individuals; to assess the biological potential and control the number; to determine the age of the individuals; to determine the sex of the individuals; 2
What is the area of ​​ecological activity?; part of the territory where individuals live and perform life functions; number of individuals in the population; reproduction rate; number of annual migrations; 1
What are migratory movements?; permanent residence in one place place; reproduction of individuals; reduction of population size; movement of individuals from one area to another for more favorable conditions; 4
What is birth rate?; death rate; number of migrations; birth rate in the population; population density; 3
What is mortality?; death rate in the population; birth rate; number of individuals per unit area; population growth rate; 1
What is the age and gender structure of the population?; distribution of individuals by age category and gender; number of individuals per unit of area; speed of population migration; birth rate in the population; 1
