Assignment #2: The Replication of DNA in Escherichia Coli Due Date: Feb 8, 2016 at 9:00 AM CST 1a. A procedure in which a small amount of DNA material is immersed in concentrated solution, cesium chloride (CsCl), and soon after placed in centrifuge until the point where equilibrium is achieved is called density-gradient centrifugation. Contrasting techniques involving diffusion and sedimentation form a persisting CsCl concentration gradient. Furthermore, the concentration gradient and pressure…

the nine limits for keeping the planet while another professor told RT Earth could be finding an imminent human-made extinction of numerous species. Those nine contain carbon dioxide concentrations, preserving at 90 percent, using phosphorous and nitrogen, keeping 75 percent of first woods, aerosol emissions, stratospheric ozone depletion, ocean acidification, fresh water use as well as the dumping of pollutants. "The planet has been our closest friend by buffering our activities and revealing…

What are earth’s resources? 1)Water Water is an important part in the life of all living organisms on Earth. Without water, the plants would die cause of require water to make photosynthesis. Besides, the humans and animals would also die cause of thirsty. Otherwise, we use water in our daily activities such as washing hands, cooking, watering plants, bathing, washing clothes and many more. Water covers the surface of Earth by almost 71%. The water on Earth occurs in three states of matter…

antifungal agent in clinical practice. Azoles are two types i.e. imidazoles contain two nitrogen atoms, and the triazoles contain three nitrogen atoms which was classified according to number of nitrogen atoms presents in this cyclic organic molecules. Azole drugs target the key enzyme i.e. the lanosterol 14-alpha demethylase, encoded by ERG11 gene. This inhibition occurs through the binding of the free nitrogen atom of the azole ring to the iron atom of the heme group of the enzyme. That leads…

Acid rain is any form of precipitation that has unusually high acidity (a pH level below 5.6) and caused by the transformation of nitrogen oxides and sulfur dioxide into secondary pollutants. pH is is a scale used that measures the acidity of liquids and ranged from 0 to 14. The lower the number, the higher acidity, or the higher concentration of hydrogen ions. 0-5 is considered acidic and as you move up to 7, this indicates the substance is neutral. The higher numbers on the scale indicate…

Organic food gets more popular every year. Many people decide to buy organic food instead of conventional food every day. But organic food is not only better for the human body, the organic food industry will also help overcome many problems. In the majority of our history, agriculture could be described as organic. But in the 20th century, scientist discovered a wide range of new chemicals which were useful for growing food. The organic farming movement started in the 1940s in response to the…

1) Compare and contrast highly developed countries (HDCs) and less developed countries (LDCs). Include in your answer three examples of countries in each category; a description of the gap between categories; and the similarities and differences that one might expect to see in these types of countries. 2 points According to the textbook “Environment” High Developed Countries or HDCs, like the United States, Canada or Japan, are represented by 9% of the world’s population while maintaining more…

Crop and livestock production is a major source of two greenhouse gases, methane and nitrous oxide. The latter is produced by the leaching, volatilization and runoff of nitrogen fertilizers and the breakdown of crop residues and animal wastes. Through burning of biomass, agriculture also releases large quantities of carbon dioxide into the atmosphere. Agriculture also stands to suffer adversely from climatic change. In tropical environments the effects of climate change on agriculture and hence…

One thing that surprised me about the car was that the car tires were filled with nitrogen gas instead of compressed air. Nitrogen is a colorless and odorless non-toxic gas used to reduce the temperature of the tire and increase its lifespan. In races, it may be able to keep tire pressure more constant and slow pressure loss without reacting to the tire and rim materials. Another thing that surprised me about the car was its design and build. What really caught my eye was that the inside of the…

he was able to discover the atomic nucleus, which housed most of the atom’s mass, and later the proton in 1917, which was the positively charged particle in the nucleus. In his discovery of the proton, Rutherford converted nitrogen atoms into oxygen atoms by crowding nitrogen with alpha particles. While Rutherford’s Atomic Model was not necessarily correct, it lay down a foundation for the model of the atom, which would be corrected in the future, and was an important step in creating the…
