When a mixture of different substances is rotated at extremely high speeds within a closed path (in your case a closed container), substances of higher mass often go on to the outermost path and lighter particles experience the nearest to rotating axis. The same principle can be used in centrifuge oil cleaning. Researchers are very careful when designing a questionnaire for use in a population and health survey to minimize prejudice. For example, they include the duration of the last sexual intercourse. Therefore, the non-response rate to sexual intercourse in Latin America and sub-Saharan Africa is low (1-8%). Although a considerable number of women started sexual relations at least a year prior to the first trade union, few women had normal relations before the first union. In sub-Saharan Africa, premarital sexual relations were more frequent than in Latin America and Trinidad and Tobago. For example, the highest percentage of children aged 15 to 17 is Uganda (32%) and Trinidad and Tobago (1%) the lowest. For children aged 22-24 years, from 90% in Ghana to 6% in Trinidad and Tobago. The age of first marriages is not necessarily parallel to the trend of the first sexual intercourse. Therefore, family planning programs should tell unmarried women the risk of even occasionally getting pregnant. They should also use sex-dependent methods, such as condoms or vaginal methods. During their reproductive years, women are married on average for 15 years and have an active sex between the ages of 0.5 and 2 years. 85% of married women had sexual intercourse within the first three months of the survey. However, 5-38% of women who use birth control pills have no sexual intercourse. Therefore, reducing fertility can not be attributed solely to the use of contraceptives. The frequency of monthly sexual intercourse declines with the duration of marriage, and the rate of decline varies from country to country. Women who want more children communicate more often than not wanting more children and those who are undecided. Women who use the independent sex more often have more sexual intercourse with women who use the same sex-dependent approach.

The endocrine system is really a band of glands that regulate our bodies with hormones. The glands are ductless, in order that they release hormones directly into the bloodstream.
