Numerous human activities increase CO2 emissions in the atmosphere. The expected results from the readings would be an increase in atmospheric CO2 concentrations due to industrial activities burning of fossil fuels. Global warming is worrying product of this.
Data from the readings showed a steady increase in CO2 emissions. The map of the world shows low CO2 emission because fossil fuels combustion had not began. Accumulation levels of CO2 increase rapidly over the years especially in the Northern Hemisphere. The annual growth rates of CO2 emissions are an indication of the high amounts of CO2 concentration that have caused the greenhouse effect and therefore contributed to global warming.

The change in temperature is attributed directly due to increased in emission of greenhouse gases, largest concentration of which is carbon dioxide. The increased emission arises from human activities in the transport and energy sector (US Environmental Protection Agency).
The polyphenols in tea are known to have antioxidant properties which can quench free radical species, and also pro-oxidant activities that appear to be responsible for the induction of apoptosis in tumor cells. The bioavailability of these natural compounds is an important factor that determines their efficacy.
Microscope is a valuable tool in the field of science, as it is used to magnify the specimens for better understanding of the cells and its structures. Since many cells are too small to be seen through the naked eye, microscope is used for the magnification. The main function of microscope is to increase the resolution.

Since 19th century scientists were aware of some unique identity of an individual which distinguish from others, like finger prints. In 1970, DNA was established as key element in human life and which makes individual as unique creature. Variability in DNA sequences among individual to individual have attracted forensic experts to develop technique based on DNA to identify individual or criminal similar to finger prints.
The seed cones are closed before fertilization and after fertilization, they develop into seeds and the scale opens. When the scales near the top of the cone were opened, the seeds were visible and they contained a wing. The
