Sonar testing has caused whales to die in mass amounts.
They use their resources and habitats around them to survive.
Answer:
DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin. Chromatin, in turn, loops and folds with the help of additional proteins to form chromosomes. Condensing DNA into chromosomes prevents DNA tangling and damage during cell division.

Explanation:
Deoxyribosenucleic acid, commonly called DNA is the stored form of genetic material in living cells. It contains the information needed by an organism to survive. A segment of the DNA that encodes the necessary information needed to produce a particular protein that determines a trait is called GENE.
The DNA consists of long polynucleotide chains, hence, due to Its length, it cannot git into the cell. The cell then devises a means by wrapping the long strands of DNA around certain proteins called HISTONES. This initially forms a NUCLEOSOME structure, then continuous wrapping around histones and condensation forms the visible CHROMOSOME structure.
Now, the CHROMOSOME contains the DNA molecule, which contains protein-coding segments called GENES. The information contained on the gene is used to produce a protein that is responsible for a particular TRAIT in the organism.
