Explanation:
Heterochromatin in terms of accessible of the cell's machinery is termed as the region whereby the nucleosomes are tightly packed toghether such that the cell's transcriptional machinery is unable to access this regions. Examples of regions where this is found is at the centromeres, the telomeres and some other few regions in the chromosomes.
Euchromatin in terms of accessibility is the region wherein the nucleosomes are loosely packed such that the cellular processes machines is able to get access to the DNA.
The cell makes DNA in highly compatible state accessible by understood some epigenetic mechanisms such as modification of the histone tails. An example is acetylation; this allows addition of an acetyl group to specific regions on the tail of particular histones that allows for the unwrapping of the history from the DNA making them accessible. This is carried out by some enzymes known as histone acetyltransferases (HATs). Another example is phosphorylation: this does the same as acetylation.

Answer:
Elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision. In the collision between the two cars, total system momentum is conserved.
