The dlagram showsa model of how bacteria reproduce by cell division.
Which two statements explain what this model shows?
A. It shows asexual reproduction.
D B. It shows offspring that have the same genes as the parent.
C. It shows sexual reproduction.
O D. It shows how genetic variation develops in offspring.

This is asexual reproduction  and it shows offspring that have the same genes as the parent, since the genetic material was copied before the division.

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.
