Answer;
C. it is the part f the atom with the greatest mass
Explanation;
The nucleus of an atom is a small dense region at the center of an atom that contains protons and neutrons.
Almost all the mass of an atom is located in the nucleus, with a very small contribution from the electron shells.
The protons are positively charged which gives the nucleus a positive charge while the neutrons have no charge.
I think the correct answer from the choices listed above the first option. In a polar covalent bond, the distribution of common electrons are <span>not shared evenly due to a greater positive charge from one atom’s nucleus. Hope this answers the question. Have a nice day.</span>
The individuals gametes cells would be damaged, possibly taking his ability to have offspring.
Crossing over contributes to genetic variation by exchanging chromosomal segments between non-sister chromatids of homologous chromosomes.
What is crossing over?
- Crossing over is the exchange and recombination of genetic components between the homologous chromosomes.
- This occurs in the pachytene stage of the meiosis-1 of the meiotic division.
- Crossing over occurs with the help of an enzyme and the enzyme responsible for crossing over is called Recombinase.
Thus, crossing over contributes to genetic variation by exchanging chromosomal segments between non-sister chromatids of the homologous chromosomes.
