Double-stranded DNA loops around 8 histones twice, forming the nucleosome, which is the building block of chromatin packaging. DNA can be further packaged by forming coils of nucleosomes, called chromatin fibers. These fibers are condensed into chromosomes during mitosis, or the process of cell division.
Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
During DNA packaging, long pieces of double-stranded DNA are tightly looped, coiled, super coiled, and folded so that they fit easily within the cell. This highly compacted DNA is then arranged into structures called chromosomes.

Answer:
D. mass feeder
Explanation:
A) suspension feeder
B) fluid feeder
C) deposit feeder
D) mass feeder
<em>Suspension feeder requires capturing of food that are suspended in water through the use of specialized organs.</em>
<em>Fluid feeding involves feeding on liquid (such as blood) emanating from other organisms.</em>
<em>Deposit feeding involves feeding on sediments</em>
<em>Mass feeding involves ingestion of scraps of different food materials.</em>
Hence, the correct option is D.
Answer:
Your body sends a message to the lungs and tell the lungs to breathe in more oxygen so that the oxygenated blood can travel to the muscles oxygenating the cells within that specific muscle and giving them energy to use the sugars stored in fat or food from digestion. The heart beats faster so that the cells supply keeps up and continues to beat fast for that specific diration of time until your breathing slows down and it no longer needs to work as fast to supply the muscles with as much blood.
The main function of the circulatory system is to move blood and lymph<span> through the body. Doing this transports nutrients and oxygen to the cells of the body and removes waste products such as carbon dioxide.</span>
