Nitrogen Cycle Questions 1. Nitrogen is both the __most abundant element__ and in organisms it is the raw material of two main macromolecules __ammonia and nitrite which build proteins and _nitrates which build your genetic material‚ DNA. 2. In the atmosphere it is found in the form of N2 which is __nitrogen gas____. 3. These Nitrogen molecules then need to go through a process called __nitrogen fixation__ in order to be converted into molecules that living organisms can use readily. 4. Two forms

INTRODUCTION: Molecular biology began more than 40 years ago with Watson and Crick‘s discovery of the double helix structure of deoxyribonucleic acid DNA and that continued with Cohen and Boyer’s. This discovery of the techniques that called as biotechnology nowadays has had an enormous impact on the nature of research and development. This technique has potential to generate great benefits in improved of human life by through of many applications which play role in improvements of medicine‚ agriculture

1. Living organisms play an important role in the recycling of many elements within an ecosystem. One such way this idea can be proven is through the study of carbon in an ecosystem. Plants‚ for starters‚ are a major part of this carbon cycle. During photosynthesis‚ plants remove carbon dioxide from the atmosphere and release oxygen as a waste product. Another major contributor to this vital cycle is the human being. The average human being goes through respiration each day to help maintain

DBQ Political‚ religious‚ and social factors affected the work of scientist in the sixteenth and seventeenth century in many ways. They were the reasons why natural philosophers questioned‚ studied‚ and continued to find new information in their discoveries. Developing a new scientific worldview must have required an abundance of controversy dealing with these important factors. There were people who believed that the discoveries made should not interfere with political power. *Thomas Hobbes
