lesya692 [45]

Answer:

Mitosis

Explanation:

A cell that contains the same DNA as its parent cell is a product of mitosis.

  • Mitosis is a cell division process that takes place in somatic cells.
  • In meiosis a single cell divides to produce two daughter cells each having the same DNA as the parent
  • Mitosis ensures that the same DNA is found between the parent
  • Mitosis is used for repairing and production of new cells.

7. Suppose each of these isotopes emits a beta particle. Give the iso-
Volgvan

In a beta emission, the mass number of the daughter nucleus remains unchanged while the atomic number of the daughter nucleus increases by one unit. The following are isotopes produced when the following undergo beta emission;

1) potassium-42  ------> Ca - 42

2) iodine-131 ------------> Xe - 131

3)  iron-52 ---------------> Co - 52

4)  sodium-24 -----------> Mg -24

The daughter nucleus formed after beta emission is found one place after its parent in the periodic table.

Regarding the stability of the daughter nuclei, a nucleus is unstable if the neutron-proton ratio is less than 1 or greater than 1.5.

Hence, the following daughter nuclei are stable; Ca - 42, Xe - 131, Mg -24.
