I think it is A as well because skin cells do not contribute genetic material to sex cells.
The allele is dominant. What this means simply put is that there is a much higher chance of it occurring than of blue eyes being on the kid. If one parent has brown eyes and the other has any other, there is a higher chance that a brown eyes allele will be used.
B & D
Protons and neutrons are energy particles found in the nucleus of atoms.
Explanation:
The forces that hold the protons and neutrons together in the nucleus are called strong nuclear forces. These forces are attractive over short distances and repulsive over long distances. This is why protons that are positively charged are held together in the nucleus despite their repulsive tendencies. However, as the nucleus gets larger because of the larger number of protons and neutrons in the nucleus, the distance with which the string nuclear forces are attractive is surpassed.
The binding energy in the nucleus will, therefore, be surpassed by the repulsive forces of strong nuclear forces over long distances causing the atomic nucleus to lose some neutrons.
