Embryonic Development Every species undergoes embryonic development in a different way. In general, genes code for specific synthesis of proteins that determine what organs and systems will be composed. However, all species differentiate types of cells in different ways, which can include an uneven distribution of cytoplasmic determinants (can activate genes to differentiate between types of cells.) Additionally, the differences in cells are based on their location in the developing embryo. These two tactics lead to cell differentiation where cells become different types as well as morphogenesis or the way an animal takes shape.

Demographics of the world

AP Human Geography Due Date Go to my website for the 2015 World Population Data Sheet Use the highlights at the beginning of the report to answer the first 10 questions What are the changes in the most populous countries from 2015 to 2050? What regions have the highest and lowest fertility rates? What does this mean for that region? Analyze Pop Clock data?.what are 3 stats that stand out to you? Explain why. How does the increasing age of marriage affect the population stats? What are some possible large purchases in the given countries that have seen significant increase in decisions by women? Look family planning, what country saw the highest growth? What may have happened in 2003 that changed that number significantly? (educated guess here or research that country)

Changes in Population What is a Population? ? A group of organisms of the same species ? living in the same habitat ? at the same time ? where they can freely interbreed How Can Populations Change MortalityNatality (Fertility) Immigration & Emigration Fertility ? Crude Birth Rate (CBR) live births per 1,000 people ? Total Fertility Rate (TFR) avg. number of children born to a woman ? Life Expectancy ? number of years an infant can expect to live ? Natural Increase Rate (NIR) ?Excess of births over deaths results in natural increase ?Excess of deaths over births results in natural decrease Mortality ? Crude Death Rate (CDR) deaths per 1,000 people ? Infant Mortality Rate (IMR) ? number of children who die before their first birthday
