one of the causes that can increase the effect of global warming. Air pollution is caused by certain gases which pollute the air such as carbon dioxide (CO2)‚ sulfur dioxide‚ methane‚ CFC (chlorofluorocarbons)‚ carbon monoxide (CO)‚ aerosol‚ and nitrogen dioxide. Some of these gases are already in the atmosphere; some are produced by human activities. To prevent the condition of the air from getting worse‚ there are some solutions we can do from now; small steps for a bigger change. This essay will

Tomatoes being a very sensitive plant require these nutrients more and as a result using compost helps them gain those nutrients. The nitrogen in the compost which will be absorbed helps plants grow quickly whilst also allowing the leaves to stay green. Nitrogen also aids in photosynthesis as it helps with the green pigment‚ chlorophyll. Phosphorus encourages the growth of roots‚ and helps with the growth of the plant. Potassium also assists in

method of creating Ammonia‚ which was extremely rare at the time‚ the process is named “Haber Process” as this is very scientist to be invented by Fritz Haber. Haber created a way of applying high temperature and high pressure with iron to combine nitrogen and hydrogen in their gaseous forms to produce Ammonia‚ which is also a reversible reaction. The nitric acid in ammonia can be used as manufacturing agriculture fertilizer and explosives. Overall‚ it supports German in a very important way as it

Based on the conditions of early Earth‚ what conclusion can you draw about the amount of anaerobic respiration that was occurring at Earth’s beginning? Explain your answer. A: The atmosphere of early Earth was made up with almost of different nitrogen gases‚ water vapor and carbon dioxide. There wasn’t any pure oxygen or I should say there wasn’t any breathable oxygen in the air in those days. The first form on earth had to develop in the absence of oxygen using the anaerobic respiration. All
