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 […]
What is the importance of studying earth science?
What is the importance of studying earth science? Earth Scientists make many beneficial contributions to society, by: understanding climate change and its dramatic consequences. monitoring geohazards and predicting volcanic eruptions and earthquakes. discovering and managing the world’s resources: hydrocarbons and precious minerals. Can studying be fun? The answer is yes, and today, we’ll be covering […]
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? […]
How can we stop population growth?
How can we stop population growth? Reducing population growth Contraception. Abstinence. Reducing infant mortality so that parents do not need to have many children to ensure at least some survive to adulthood. Abortion. Adoption. Changing status of women causing departure from traditional sexual division of labour. Sterilization. What are the negative effects of rapid population […]
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 […]
Why is air a poor conductor?
Why is air a poor conductor? Air may be a bad conductor of heat because its molecules aren’t in continuous contact with one another. Air molecules are too far to disperse heat to at least one another efficiently. Heat is transferred or conducted by molecules and atoms that are very closely bonded together and vibrating […]
Do waves have mass?
What are the 2 main types of glacier?
What are the 2 main types of glacier? There are two main types of glaciers: continental glaciers and alpine glaciers. Latitude, topography, and global and regional climate patterns are important controls on the distribution and size of these glaciers. What is the difference between an ice cap glacier and a piedmont glacier? The biggest types […]
