Answer:
2 meters (3 Gb of base pairs)
Explanation:
The human genome is composed of 3 billion (3 Gb) base pairs, which are organized in 23 pairs of chromosomes. Within the nucleus, DNA is compacted by histone proteins to form nucleosomes and these structures are then organized in chromatin fibers that undergone higher-order compaction. The compaction of chromatin fibers is accomplished by proteins and Matrix attachment DNA regions (MARs) that bind specifically to the nuclear matrix. In an unwound state, each cell nucleus in the human body has approximately 2 meters of DNA (if the DNA molecule would be stretched end-to-end).
Answer:
In Gastrointestinal system:
When we eat food or drink water, it travels from our mouth, down our oesophagus and into our stomach. In the stomach, the food is broken into tiny pieces that are mixed with stomach liquids. This mush of food and stomach liquids is called chyme. The chyme travels into the small intestine. This is where osmosis takes place.
In our Kidneys:
Our kidneys keep blood and tissue fluid (internal environment) 'clean' by removing urea, excess water and other wastes and excreting them. This controls the amounts of dissolved substances in blood and tissue fluid, a process called osmoregulation. If tissue fluid becomes too concentrated, cells will lose water by osmosis and become dehydrated and if it becomes too dilute, cells will take in excess water by osmosis.

After food is swallowed it is moved down the esophagus by peristalsis. The muscles in the stomach, small intestine, and large intestine continue the process. Food is further digested and broken down as it moves through the digestive tract, aided by digestive juices that are added along the way.
