What electron microscopes are used for? Electron microscopy (EM) is a technique for obtaining high resolution images of biological and non-biological specimens. It is used in biomedical research to investigate the detailed structure of tissues, cells, organelles and macromolecular complexes. How do electron microscopes help us? The development of the electron microscopes therefore helped scientists […]
Can a magnetic field do work on a charged particle?
Can a magnetic field do work on a charged particle? An electric field may do work on a charged particle, while a magnetic field does no work. The Lorentz force is the combination of the electric and magnetic force, which are often considered together for practical applications. Under what conditions does a magnetic field do […]
How far can you transmit electricity?
How far can you transmit electricity? about 300 miles Can you move air with electricity? Ionic air propulsion is a technique for creating a flow of air through electrical energy, without any moving parts. Because of this it is sometimes described as a “solid-state” drive. It is based on the principle of electrohydrodynamics. Is electricity […]
What is the difference between interference and superposition?
What is the difference between interference and superposition? Superposition is basically the addition of different waves. Interference typically refers to a condition in which the superposed waves either largely cancel (destructive interference) or largely reinforce (constructive interference). This means that they are the same, or nearly the same, frequency. What is the main difference between […]
Why is supply and demand so important?
Why is supply and demand so important? Supply and demand are both important for the economy because they impact the prices of consumer goods and services within an economy. According to market economy theory, the relationship between supply and demand balances out at a point in the future; this point is called the equilibrium price. […]
When two heterozygous parents reproduce what type of offspring can they produce?
When two heterozygous parents reproduce what type of offspring can they produce? In addition, crossing two individuals that are both heterozygous will yield, on average, 50 percent heterozygous offspring; half of the remaining offspring, on average, will be homozygous for the dominant allele and half homozygous for the recessive allele. What color are the kernels […]

What characteristics do photosynthesis and cellular respiration have in common?
What characteristics do photosynthesis and cellular respiration have in common? Both processes involve a cycle of chemical reactions. Both processes involve energy conversions. Both processes use and produce ATP. Both processes use an electron transport chain. What is the relationship between photosynthesis and cellular respiration simple? Photosynthesis converts carbon dioxide and water into oxygen and […]
Are jelly and jam complements or substitutes?
Are jelly and jam complements or substitutes? Also, are jelly and jam complements or substitutes? Complementary goods are rarely symmetrical. Peanut butter and jelly is a good example of symmetric complements – they have comparable price points, and both generally can be improved by purchase of the other. What happens when the price of a […]
