What are the key concepts in the evolution theory of Darwin? Branching descent and natural selection are the two key concepts of Darwinian Theory of Evolution. Why was Lamarck’s theory wrong quizlet? LaMarck’s theory was incorrect because he did not know how traits were inherited & that the organism’ behavior has no effect on inherited […]
Are eigenvectors Orthonormal?
Are eigenvectors Orthonormal? 1) Eigenvectors can always be scaled. So if v is an eigenvector then so is av for a∈k∗. So if each eigenvalue has multiplicity one a basis of eigenvectors is automatically orthogonal (and can be made orthonormal as above). In general we need to find an orthogonal basis of each eigenspace first, […]
When light is incident on a soap film of thickness 5?
Is a 3 year degree worth anything?
Is a 3 year degree worth anything? It’s true that three-year degrees, even if accelerated, would likely never be academically equivalent to four years. But three-year degrees would offer students a much-needed fork in the road. If more students moved to a college after year three, more would be working within four years of high […]
Is DownTek real down?
Is DownTek real down? What is DownTek™ Water Repellent Down? DownTek™ is down that has been treated with a DWR (Durable Water Repellency) and renders the down hydrophobic. DownTek™ is currently available in either it’s original C6 formula, or the PFC-Free™ formula. Why is down a good insulator? Down feathers are great thermal insulators. The […]
What other evidence must be taken into consideration in addition to DNA evidence?
What other evidence must be taken into consideration in addition to DNA evidence? Along with DNA evidence, fingerprints, physical evidence (objects) and witnesses must be taken into consideration. What do investigators need to be aware of when using PCR and DNA as evidence? Because a new DNA technology called “PCR” replicates or copies DNA in […]
Which type of energy transfer does not require matter?
Which type of energy transfer does not require matter? The transfer of thermal energy by conduction and convection does not require matter. 2. The transfer of thermal energy by radiation does not require matter. What would result in being able to dissolve a greater amount of gas in a solution? An increase in temperature decreases […]
What do switches do in a circuit?
What do switches do in a circuit? A Switch. An electrical switch serves the purpose of controlling the flow of electrical current within a circuit. It can be used to both inhibit the flow of the current or to initiate it. What happens when you remove a bulb from a parallel circuit? Nothing happens to […]
What is the formula of law of inertia?
What is the formula of law of inertia? Inertia of an object is the resistance offered by the object to change in its motion or position. Simply, it is the resistance that the object will apply to an external opposite force. Translational Inertia = ma, where “m” is the mass, and “a” is the acceleration […]
What are 4 major properties of a magnet?
What are 4 major properties of a magnet? They are: Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel. Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other. Directive Property – A freely suspended magnet always points in a north-south direction. What is the main […]
