I am: A) DNA
DNA is double-stranded molecule which is often also it's most known feature. Perhaps less known (depends on who you ask) are facts that it also has thymine and not uracil (uracil is found in RNA). It has four nitrogen bases and it contains deoxyribose sugar (another hint that it's DNA and not RNA).
Answer:
Option 3, Heuristics
Explanation:
Heuristics thinking implies usage of past experiences or judgments or the memory of most relevant and similar incidents to quickly formulate judgments and solutions and make decisions. Such judgments are biased most of the time as they are based on the perseverance of an individual instead of logic and conceptualization of any scenario or incident
Hence, option 3 is correct
Answer:
Since electromagnet waves do not need a medium they can travel through space. Sound waves can't travel through space because they need a medium.
Explanation:
Unlike the carbon cycle, the phosphorous cycle does not involve a gas phase and is therefore not considered as a true cycle. This is what distinguishes it also from such cycles as the water and nitrogen cycles.
Very little phosphorous circulates in the atmosphere because at earth's normal temperatures and pressure, phosphorous together with its various compounds are not in gaseous form, though small amounts of phosphoric acid may make their way into the atmosphere, and contributing to acid rain in some cases.
The largest reservoir of phosphorous is in sedimentary rock.
