Answer:
Explanation: When this study was carried out by Meselson and Stahl, their findings are compatible with the trend expected by semi-conservative analysis, establishing this as the right template. The two parent strands are split as DNA replicates, and each strand acts as a blueprint for a new DNA strand synthesis.
After the first replication, there are two DNA double helices each marked as superscript 14 N slash superscript 15 N. After the second replication, four double helices of DNA are produced. Three of them are marked as 14 N superscript slash 15 N. Two other DNA was marked as 14 N slash superscript 14 N.
Remember that after a round of testing, Meselson and Stahl were able to rule out the moderate template based on the results. At that point, though, they were unable to rule out the dispersive model because that model predicts the same trend as the semiconservative model. But after two trials, the findings made it possible for them to rule out the dispersive design.
Answer:
Convection takes place in the atmosphere, in the oceans, and in Earth's molten subcrustal asthenosphere. Convective currents of air in the atmosphere are referred to as updrafts and downdrafts. In addition to heat transfer, convention can be driven by other properties (e.g., salinity, density, etc)
Explanation:
Answer:
1. Iron (ferrous)
2. Zinc
Explanation:
Iron is a major component of hemoglobin which is responsible for the transportation of oxygen from lungs to all cells of the body, while excess iron has also negative effects on our body such as it causes liver disease (cirrhosis, cancer), heart attack, diabetes and sometimes it causes death. Zinc also plays a vital role in our body because it is a main component of all cells and also provide protection against microbes. It also needed for the production of DNA and protein. Zinc in excess amount causes copper deficiency, Nausea Stomach Pain and Diarrhea.
