The notation is actually written in this way (shown in the attached picture). The X is the symbol of the element. So, for potassium, the symbol is K. The A represents the mass number of the isotope. In this case, that would be equal to 39. The Z represents the atomic number of potassium, which is 19. Therefore, the symbol for the isotope is:
³⁹₁₉K
Answer:
d. they are both involved in the division of somatic cells
Explanation:
Mitosis and meiosis are both types of cell divisions that occur in the system of living organisms. However, mitosis and meiosis are different in the type and number of daughter cells they give rise to and also where they occur.
Mitosis, which takes place in the SOMATIC OR BODY CELLS of living organisms, give rise to two daughter cells that are genetically identical to their parent cell. On the other hand, meiosis takes place strictly in the CELLS OF REPRODUCTIVE ORGANS, and gives rise to four genetically different daughter cells.
