Not always because there could be birth defects, mutations, or other variables.
Plant cells have cell walls, while animal cells don't have cell walls.
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.
