society. Background After World War 2 had ended‚ there was an influx of birth and a rise to the population in Japan. There are a host of reasons attributed to this influx; Firstly‚ soldiers had just returned from the war to their wives and that because of this‚ there was a lack of family planning which resulted in a baby boom. Secondly‚ the economic policies adopted by the government which included having a high savings rate resulted in Japan to eradiate famines‚ epidemics‚ and infanticides on a

for farming‚ which will lead the planet epically less developed countries toward food crises. Overpopulation is results from various causes such as not having the capacity to control family size or lack of family planning‚ improved medicine‚ low death rate‚ lack of global epidemics‚ and poor education…etc. These are the main reasons behind overpopulation. Overpopulation has bad impact on many aspects in our life such as: environment‚ society‚ and economy. The solution for such an issue like growth

Changing the Rate of Reaction PART 1: PARTICLE SIZE Question: How does changing the particle size of marble (CaCO3) affect the rate of reaction when it is added to hydrochloric acid (HCl)? Hypothesis: If I change the particle size of marble to test how to change the rate of a chemical reaction‚ than the chemical reaction with the smallest marble particles will produce CO2 the quickest because the larger the surface area‚ the more place the hydrochloric acid will have to collide with the marble

Some Causes of Fertility Rates Movements Claire Norville Rocio Gomez Robert L. Brown ABSTRACT Fertility patterns are different between countries and over time. Many different factors can affect the fertility rate. This paper will discuss the different factors that have an effect on the fertility rate. Some are economic while some are social. The economic factors will be based in the theories of Richard Easterlin‚ Diane Macunovich‚ Butz & Ward‚ and John Ermisch. The social factors that

Diffusion is a way nonvascular plants can get water. It is the movement of molecules from an area of higher concentration to an area of lower concentration until they are equal. An example of diffusion is red food coloring. When you put food coloring in a glass of water the color will spread through the water until all of it is a red tint. This shows the molecules of the food coloring equally distributed in the area of the water. Osmosis is a special type of diffusion where only the water molecules

based in two different counties and neighbors one another. They both carry high crime rates; however‚ their economic stability is a huge factor in stabilizing the current crime rates and reducing the amount of heinous crimes that occur. Three main crimes that will be used to compare Modesto and Stockton are sex‚ thefts (burglaries) and murders. To help see the comparable data between each city‚ we have designed a data table that compares the yearly statistics to each specific crime and the city they

1. Introduction: This investigation will show the effect of temperature on the rate of reaction. The Berocca tablet was reacted with hot water (47oC) and then with cold water (20oC). In the hypothesis‚ it was predicted that the temperature will be inverse proportional to the time Berocca tablet reacts with water to produce 50ml of carbon dioxide gas. Through the result table‚ we can see that the hypothesis is supported and it was correct. In the conclusion‚ it was shown that the temperature has the
