Well according to my understanding there is no such thing as a cell wall. But if they are different then the cell membrane is basically a guard. In order for things to come in and out of the cell, they must pass through the cell membrane. Also, the cell membrane protects the cell from germs and any harmful objects. Hope this helps!
Redshift is said to be experienced when the light or any other electromagnetic radiations from an object undergo an increase in the wavelength but it does not mean that the light literally becomes red.
Redshift occurs due to the expansion of space. It means the farther away the galaxy is from us, the more space it has expanded in the time.
Because as the light left the galaxy, more of the light has been stretched and so more redshifted the light is.
The average atomic mass of uranium = 313.826 amu
What is average atomic mass ?
The weighted average mass of the atoms in a naturally occurring sample of an element is the average atomic mass, also known as atomic weight. Unified atomic mass units (u), where 1 u is equal to precisely one-twelfth the mass of a neutral atom of carbon-12, are the standard units used to express average masses.
