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.

Sayyid drew a diagram to compare the gravitational and

Jlenok [28]

Gravitational: A.is attractive only

Electromagnetic: C.attracts and repels

Both: D.has an infinite range

Explanation:

The two forces mentioned in this problem are:

- Gravitational force: this force is the force that is exerted between any object with mass. The magnitude of the force is given by

$F=G\frac{m_1 m_2}{r^2}$
