IN: Is it true that is saline water the same as salt water?

Saline water (more commonly known as salt water) is water that contains a significant concentration of dissolved salts (mainly NaCl). The salt concentration is usually expressed in parts per thousand (permille, ) or parts per million (ppm). The United States Geological Survey classifies saline water in three salinity categories. Salt concentration in slightly saline water is around 1,000 to 3,000 ppm (0.1--0.3%), in moderately saline water 3,000 to 10,000 ppm (0.3--1%) and in highly saline water 10,000 to 35,000 ppm (1--3.5%). Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 grams of salt per one liter (or kilogram) of water. The saturation level is dependent on the temperature of the water. At 20 C one milliliter of water can dissolve about 0.357 grams of salt; a concentration of 26.3%. At boiling (100 C) the amount that can be dissolved in one milliliter of water increases to about 0.391 grams or 28.1% saline solution.

OUT: yes

IN: Is it true that are the marines a branch of the army?

The Marine Corps has been a component of the U.S. Department of the Navy since 30 June 1834, working closely with naval forces. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers.

OUT: no

IN: Is it true that is the heart part of the central nervous system?

The autonomic nervous system controls involuntary responses to regulate physiological functions. The brain and spinal cord from the central nervous system are connected with organs that have smooth muscle, such as the heart, bladder, and other cardiac, exocrine, and endocrine related organs, by ganglionic neurons. The most notable physiological effects from autonomic activity are pupil constriction and dilation, and salivation of saliva. The autonomic nervous system is always activated, but is either in the sympathetic or parasympathetic state. Depending on the situation, one state can overshadow the other, resulting in a release of different kinds of neurotransmitters. There is a lesser known division of the autonomic nervous system known as the enteric nervous system. Located only around the digestive tract, this system allows for local control without input from the sympathetic or the parasympathetic branches, though it can still receive and respond to signals from the rest of the body. The enteric system is responsible for various functions related to gastrointestinal system.

IN: Is it true that can you die if you sleep with the fan on?

Fan death is a well-known superstition in Korean culture, where it is thought that running an electric fan in a closed room with unopened or no windows will prove fatal. Despite no concrete evidence to support the concept, belief in fan death persists to this day in Korea.
