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 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 […]
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 […]

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 […]
