Answer:
It would be D
Explanation:
You are on the right track, but D is bascially what everything has to be made of.
Bone remodeling is a process in which bone tissue is replaced by newer bone tissue. It can be used to determine age because we take the bone tissue that was removed from the skeleton and based on its structure we can determine at what age was it removed from the skeleton.
<em>Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid. This cycle establishes a circular current that stops only when heat is evenly distributed throughout the fluid. For instance, a hot radiator heats the air immediately around it. The air rises toward the ceiling, pulling cooler air down from the ceiling into the radiator to be heated. This process repeats until the air in the room is evenly heated. Convection drives the Gulf Stream and other currents that turn over and mix up the waters in the world’s oceans. Cold polar water is drawn down from higher latitudes and sinks to the ocean bottom, pulled down toward the equator as lighter, warmer water rises to the ocean’s surface. The warmer water is pulled northward to replace the cold water that’s been pulled southward. This process distributes heat and soluble nutrients around the world. Thermal energy also moves within the ocean and within the atmosphere through the process of convection. During convection, cooler water or air sinks, and warmer water or air rises. This movement causes currents. Ocean currents are like rivers of water moving through the sea. The convection happens because hot water has a lower density and thus rises up to the surface where it cools and sinks down to the bottom again. When water starts boiling there is the additional effect of the formation of water vapor bubbles that have a much stronger buoyancy than hot water.</em>
Answer:
Correct question= <em>What does the history behind the elucidation of secondary structure of DNA tell you about the role of the scientific community in advancing science? Were Watson and Crick solely responsible?</em>
Explanation
The earlier discovery of nucleotide sequence and base pairing by Levene formed the basis of later discovery and formulation of double Helix DNA structure by Waston and Crick. Thus Levene work contributed to discovery of DNA double helix structure of Waston and Crick
In addition earlier work of Franklin on X-ray crystallography data, and comprehensive research on biochemical analysis of ,molecular proportion of nucleotide by Chargaff, were another supporting bedrock on which Waston and Crick built their discovery of double helix structure of DNA.
Evidently most scientific discoveries were usually arrived at from the earlier work or discoveries, and rarely in isolation.
Cellular respiration is the process by which organic sugars are broken down to produce energy. It plays a vital role in the carbon cycle because it releases carbon dioxide into the atmosphere.
