Legal protection and conservation plan for these endangered subspecies should be established. However‚ organic evolution has been taking place for 3.5 billion years. It is impossible to study every living organism from an individual level. Biologists group and classify living and extinct organisms for many reasons such as to establish a common language or

once the railroads began to arise throughout the eastern areas of the United States. Farmers were able to transport massive amounts of food all over the states for much more profit‚ and it also benefited people in more densely populated areas where farming was scarce‚ such as New York. The agricultural industry began to grow even faster once the civil war began because food needed to be transported to towns north and south to feed the

I n the 1930’s the farming was a big boom‚ but as more people came the less and less the nutrients was taken out of the soil. The dust bowl was also known as “the Dirty Thirties” before all the migrants moved to the states the soil was rich and full of nutrients‚ but the states didn’t get much rain to keep the land fertilized. As soon as the immigrants moved they started to plant right away and the soil went from rich and full of nutrients to poor soil and the nutrients were all gone. So the

Effects of Organic Food on Drosophila Melanogaster A new study has shown that fruit flies that lived on organic foods tended to be healthier than those that lived on conventional foods. The two things that researchers based their conclusions for health on were fertility and longevity. These two things are two important aspects to a fly’s life. On both of these tests‚ the flies that were fed organic food performed better than the flies that were fed conventional food. They survived for a longer

Application of Organic Light Emitting Diode (OLED) for Display Systems: Advanced Characteristics and Possible Solutions to Challenges 1. Introduction The first organic light emitting diode (OLED)‚ which was an innovatory of electroluminescence that emits light using organic materials‚ was reported in 1987 (Tang & VanSlyke‚ 1987). OLED displays are constructed by surrounding a glass or plastic substrate with organic compounds that emit light when current passes through them (Askari‚ 2014). Continuous
