The answer is diatoms.
The organism is unicellular, but contains cell organelles, so it must be in the domain Eukaryota. It also has chloroplast, so it could be some plant or algae, but since it is unicellular it must be algae. Among the algae, diatoms are specific for their <span>glass-like cell walls with sculpturing.</span>
Random mutations are the ultimate source<span> of </span>genetic<span> variation. Mutations are likely to be rare and most mutations are neutral or deleterious, but in some instances the new alleles can be favored by natural selection.</span>
Isotopes are elements with same atomic number Z= number of protons but different mass number A, where A= Z+N, N= number of neutrons which is variable. As for radioisotopes, I’ve never heard of them before !
