What is the graph used for? Graphs are a common method to visually illustrate relationships in the data. The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space. Do not, however, use graphs for small amounts of data that […]

Why is current higher in parallel than in series?
Why is current higher in parallel than in series? The parallel circuit has very different characteristics than a series circuit. As you add more and more branches to the circuit the total current will increase because Ohm’s Law states that the lower the resistance, the higher the current. Are houses wired in parallel or series? […]

Can you make diamonds without pressure?
Can you make diamonds without pressure? Diamonds are formed when carbon is placed under an immense amount of pressure which equals 725,000 pounds per square inch. How much pressure can a diamond take? Used in so-called diamond anvil experiments to create high-pressure environments, diamonds are able to withstand crushing pressures in excess of 600 gigapascals […]
Why is lichen a pioneer species?
Why is lichen a pioneer species? Lichens are typically the first organisms to colonize bare rock. They are therefore the pioneer species in primary succession. Many organisms require soil before they can colonize an area. Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. What is the […]
Where is most marine life?
Where is most marine life? Ocean habitats can be divided into two: coastal and open ocean habitats. Most ocean life can be found in coastal habitats on the continental shelf, even if this area occupies only 7% of the total ocean area. Most of the open ocean habitats are found in the deep ocean beyond […]
What did Rutherford discover and what was his model called?
What did Rutherford discover and what was his model called? Rutherford model, also called Rutherford atomic model, nuclear atom, or planetary model of the atom, description of the structure of atoms proposed (1911) by the New Zealand-born physicist Ernest Rutherford. How did Dalton know how many atoms were in a molecule? While all atoms of […]
What is the marker of choice for detecting a myocardial infarction?
What is the marker of choice for detecting a myocardial infarction? Diagnostic biomarkers Two well known biomarkers in use for diagnosis of acute myocardial infarction are Creatine-Kinase-MB isoform and Cardiac Troponin. In 2000, Cardiac Troponin replaced CK-MB as the biomarker of choice for diagnosing a myocardial infarction [6]. Which is a common clinical manifestation following […]
