Watch the video “decoding genes at home.” the scientific advancements in this video offer a lot of hope for people who want to know their genetic risks for certain conditions. the genetic tests have some drawbacks as well. what advantages and disadvantages do you see with allowing people to test their dna at home?

explanation:

a- all cells come from pre-existing cells

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
