Which of the following BEST describes mitochondrial inheritance in humans? A. Mitochondria are inherited only from the mother. Sperm don't have mitochondria, only eggs do. B. Mitochondria are inherited only from the mother. Once the mitochondrion from the sperm enters the egg, it is inactivated. Only maternal mitochondria divide as the fertilized egg divides. C. Mitochondria are inherited only from the mother. Sperm mitochondria aren't contained in the head of the sperm, which is the only part that penetrates the egg. D. Mitochondria are inherited only from the father. Eggs don't have mitochondria, but sperm do. E. Mitochondria are inherited from both parents. Both eggs and sperm contain mitochondria, so every cell in a human body includes both paternal and maternal mitochondria.

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.

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.
