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 !
Ocean floor is the rocks from which source would most likely contain the
highest percentage of iron-bearing minerals.
<h3>Iron formation in Ocean floor</h3>
Iron are formed as thin banded forms in the ocean floor as a result of the
formation of oxygen through organisms present in the ocean such as
cyanobacteria. The oxygen formed result in the formation of these iron ores.
The iron-bearing minerals include the following:

Answer:
There is an accumulation of genetic mutations in the DNA of sperms due to its constant mitosis.
Explanation:
The germinative cells that will become sperms are under constant mitosis. During this process, DNA mutations can happen and be transmitted from one generation of cells to the other as the years go by, and more cell divisions take place, more mutations the DNA in the sperm will have. When the number of mutations reaches a certain level, his child will express these mutations and have autism.
The egg of the mother is not a factor because the germinative cells in women are not under constant mitosis, so there is not an accumulation of gene mutations. Women are born with an exact number of eggs for all their life.
