Name the process responsible for the evolution of mitochondria and chloroplasts in eukaryotes

  Symbiogenesis

The process responsible for the evolution of mitochondria and chloroplasts in eukaryotes is Symbiogenesis or endosymbiotic theory. 

This theory states that mitochondria and chloroplasts originated from bacteria entering a eukaryotic cell to form a symbiotic relationship.

Among the pieces of evidence supporting symbiogenesis are that new mitochondria and plastids are formed only through binary fission and the striking similarities between bacteria and these organelles (mitochondria and chloroplasts). Similarities include 1) They have their own DNA, which is separate from the DNA found in the nucleus of the cell. and  2) both organelles use their DNA to produce many proteins and enzymes required for their function

the correct answer is phenotype

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.
