Answer:
a: metaphase
Explanation:
the chromosomes are aligned at the metaphase plate
Interphase isn't part of mitosis because the cell doesn't divide in interphase.
An isotope of any element is the same, with a variation in the neutrons of the nucleus.
The mass number change but the atomic number doesn't.
In this case, protium, deuterium, and tritium are all hydrogen isotopes.
Protium is 1H or Hydrogen-1 is without neutrons.
Deuterium is 2H or Hydrogen-2 has one neutron.
Tritium is 3H or Hydrogen-3 has two neutrons.
