What is the most important function of stratospheric ozone? Stratospheric ozone is a naturally-occurring gas that filters the sun’s ultraviolet (UV) radiation. This is typically regarded as ‘good’ ozone since it reduces the harmful effects of ultraviolet (UV-B) radiation. A diminished ozone layer allows more radiation to reach the Earth’s surface. Why is o3 unstable? […]

What is a rock floating in space called?
What is a rock floating in space called? While it is floating around in space, a space rock is called a meteoroid. Some meteoroids create more light when they burn up. These extra-bright meteors are called fireballs and they can even be seen during the day. Sometimes a meteoroid doesn’t completely burn up as it […]
What does healthy plasma look like?
What does healthy plasma look like? Blood plasma is the yellow liquid component of blood, in which the blood cells in whole blood are normally suspended. The color of the plasma varies considerably from one sample to another from barely yellow to dark yellow and sometimes with a brown, orange or green tinge [Figure 1a] […]
What electron microscopes are used for?
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 […]
