Water cycle affects ocean salinity on different levels.
For example, evaporation of ocean water increases the salinity of the ocean, while precipitation and melting of ice decrease it, achieving the balance. Temperature, salinity and water cycle are tightly connected. As global temperatures rises, evaporation increases, and so the salinity. Salty ocean has a tendency to sink. On the other hand warmer ocean rises to the surface and this has influence on ocean currents which then impact the weather.
Nitrogen is the most important constituent of the amino acids, which combine together to form peptides and proteins. Proteins are the building blocks and are involved in structure, functioning and regulation of various body parts. They are also present in the form of enzymes and are crucial.
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.
