Answer:
The correct option is B
Explanation:
Isotopes of the same element have the same atomic number (number of protons) but different mass number. Hence, <u>all the three naturally occurring carbon isotopes mentioned in the question have 6 protons each. Since the number of protons in a neutral atom is equal to the number of electrons in the same atom, each of these isotopes also have 6 electrons</u>.
However, to determine the number of neutrons in each atom, the number of protons (atomic number) is subtracted from the mass number.
Hence, the number of neutrons in carbon-12 is 12 - 6 = 6
the number of neutrons in carbon-13 is 13 - 6 = 7
the number of neutrons in carbon-14 is 14 - 6 = 8
From the explanation above, <u>it can be noted that the number of protons and electrons in isotopes of the same element are the same while the number of neutrons in these isotopes are different</u>. Hence, the correct option is B
Answer:
Gene duplication
Explanation:
Gene duplication is an evolutionary process that includes different phenomena such as, among others, unequal crossover, chromosome rearrangement, chromosome duplication, etc. These duplicated genes are redundant in function and therefore they may accumulate mutations such as insertions or deletions at higher rates compared to single-copy DNA sequences, thereby producing homologous genomic fragments with different lengths
