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 […]
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. […]
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 […]
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 is the coldest dwarf planet?
What is the coldest dwarf planet? However, since 2006, Pluto is no longer considered to be a planet because specialists have realized that it is much smaller than we imagined, giving it the status of a dwarf planet. Today, two planets can claim the title of “coldest planet in the solar system”: Neptune and Uranus. […]
