Red blood cells (RBCs) are a type of blood cell whose role is to transport oxygen from the lungs to the peripheral tissues of the body. Oxygen diffuses from the alveoli of the lungs into the RBCs, where it binds to hemoglobin. One molecule of hemoglobin can bind four molecules of oxygen (O2).

Answer:a) decreased chromatin condensation

Explanation:

During eukaryotic cell division a chromatin becomes obvious and it is simply a mass of genetic material made up of DNA and proteins which condenses to form chromosomes.

The chromatin primarily function in the compression the DNA into a unit so compacted that will be so tiny and can fit within the nucleus.

Chromatin condensation is driven by condensins and interactions between histones.

Condensins however, are large protein complexes whose central role in cell division is chromosome organization and segregation.

Chemical manipulation as stated above is decreases the rate of chromatin condensation.
