The vicious cycle of poverty affects generations. Poverty means not having enough money to survive. There is a debate that poverty is self imposed rather than a global situation. The reasons for this problem are‚ increasing population‚ lack of education‚ discrimination‚ and mostly unemployment. The effects of poverty are intergenerational‚ ranging from high mortality rate among infants‚ mental illnesses‚ crime and violence‚ and mostly to become a burden on the economy. Overcoming poverty is not easy

Exercise 13 MITOSIS: REPLICATION OF EUKARYOTIC CELLS ANSWERS TO QUESTIONS 1. a. Mitosis and cytokinesis are often referred to collectively as "cellular division." Why are they more accurately called cellular replication? The result of mitosis is production of two cells (replicates) identical to the parent cell. The genetic material is replicated rather than divided. b. Does the cell cycle have a beginning and an end? The organization of our study of cellular events indicates a beginning and

Introduction. The business cycle or economic cycle refers to the ups and downs seen somewhat simultaneously in most parts of an economy. The cycle involves shifts over time between periods of relatively rapid growth of output (recovery and prosperity)‚ alternating with periods of relative stagnation or decline (contraction or recession). These fluctuations are often measured using the real gross domestic product. To call those alternances "cycles" is rather misleading‚ as they don’t tend to repeat

unemployment lasting more than a year. Periods of expansion Begin when economic activity starts to increase and continues until the economy reaches a peak. Now let us analyze the data taken government websites given above According to the business cycle theory an economy that undergoes no real growth for a period of six months or more is technically in recession. From seeing the table 1 of real GDP growth rate we can say that recession started from 3rd quarter of 2008 when the real GDP growth rate

Epidermis Cells Aim: To see if rhubarb changes when it is placed in solutions of different concentrations. Introduction: "Plasmolysis in Rhubarb Epidermis Cells" is an experiment to see whether or not rhubarb changed its cell structure when placed within different types or solutions. "A single layer of plant cell is placed on a micrscope slide and either distilled water or 5% NaCl solution is added to the cells. Osmosis will occur resulting in either turgid cells or plasmolysed cells." (www
