mylen [45]

False, pernicious anemia may take up to 5 years to show symptoms. However, the oxygen starts to get depleted within the first 6 months in thalassemia major.

Pernicious anemia:

In this condition, the body is unable to absorb vitamin B12 which leads to lowered amount of red blood cells which are responsible for carrying oxygen throughout the body.

Molecular evidence also proves that these organelles were once prokaryotic organisms because they show similar genetic makeup and ribosome type.

So these organelles are similar to present-day bacteria showing that they have a common ancestor.
