E = mc2 Meaning
At the beginning of the 20th century, the notion of mass underwent a radical revision. Mass lost its absoluteness. One of the striking results of Einstein’s theory of relativity is that mass and energy are equivalent and convertible one into the other. Equivalence of the mass and energy is described by Einstein’s famous formula E = mc2. In words, energy equals massmultiplied by the speed of light squared. Because the speed of light is a very large number, the formula implies that any small amount of matter contains a very large amount of energy. The mass of an object was seen to be equivalent to energy, to be interconvertible with energy, and to increase significantly at exceedingly high speeds near that of light. The total energy of an object was understood to comprise its rest mass as well as its increase of mass caused by increase in kinetic energy.
In special theory of relativity certain types of matter may be created or destroyed, but in all of these processes, the mass and energy associated with such matter remains unchanged in quantity. It was found the rest mass an atomic nucleus is measurably smaller than the sum of the rest masses of its constituent protons, neutrons and electrons. Mass was no longer considered unchangeable in the closed system. The difference is a measure of the nuclear binding energy which holds the nucleus together. According to the Einstein relationship (E = mc2) this binding energy is proportional to this mass difference and it is known as the mass defect.
Answer:
The cell membrane separates the external and internal environment of the cell. The cell membrane is composed of bilayer lipids, proteins and small amount of carbohydrates.
The lipid part is soluble in hydrophobic environment or with the hydrophobic part of other phospholipids because like molecules dissolve in like molecules. The hydrophobic part is non polar and hydrophilic parts is able to dissolve in polar area due to the interaction of same molecules with each other.
Answer:
In order to complete this project you would need to discuss the process on what happens in a healthy cell. Like what goes in the cell, what does the cell do with it, etc. If you use google and look at images that should maybe help a bit.
