Together,the number of protons and the number of neutrons determine an elements isotopes have slightly different mass numbers, the atomic mass is calculated by obtaining the mean of the mass numbers for its isotopes.
To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.
Because fungi dont live off of sunlight the are under the class of decomposes which means that they grow off of dead things getting nutrients from that
DNA replication is important because without it, cell division could not occur. With DNA replication, the set of DNA of a cell can be duplicated and then each cell that results from division can have its own entire set of DNA, and cell division can theoretically continue indefinitely.
