Answer:
It exhibits traits and metabolic instructions of the cell.
Explanation:
A DNA strand is a thin long molecule, with an average width of just around two nanometers. The remarkable thinness of the DNA strands allows them to be bundled very tightly fitted inside cells. Once DNA has been replicated adequately during the process of cell division, it is further wrapped together under a mechanism known as supercoiling. A non-condensed DNA is further condensed during supercoiling using a special protein known as a histone. A part of DNA packed around a large cluster of histones is called a nucleosome. Additional condensation leads to a chromosome or the most compact type of DNA that fits into the nucleus. It is also worth noting that this wrapping does not merely align DNA into a cell, but serves other objectives such as protecting DNA, thus ensuring metabolic instructions to the cell.
Answer:
The Epipelagic Zone (sunlight zone)
Explanation:
The depth of this zone is about 200 meters (656 meters) below the ocean's surface. Phytoplanktons dwell there because sunlight penetrates this zone which facilitates the process of photosynthesis.

C. During prophase I, SEGMENTS of chromatids are exchanged between homologous chromosomes.
Answer:
The correct answer is - to allow air and blood to escape.
Explanation:
An occlusive dressing is a dressing that involves water and airtight on the wound or the opening in first aid. It is used to protect the incision or wound to be contaminated.
In the case of the pneumothorax development, the occlusive dressing is sealed with the three-sided but the fourth side is left open so it will allow air to the escape from the pleural space and blood with the prevention of the backflow of air with inspiration.
Thus, the correct answer is - to allow air and blood to escape.
