the dead sea was once a 'normal' sea like the rest, but evapoation made a higher percentage of water disappear than normal seas so when that happens the salinity of the water increases the way the dead sea has gone. Its not that salt has been added from a mysterious source, it that water has been taken away.
Partial answer: The salinity of the dead sea is ~31.5% by weight while the salinity of the Mediterranean is ~3.5%
The surface of the Dead Sea is more than 400 meters below sea level and mineral laden water flowing into it from the Jordan River disappear by evaporation. Minerals left behind after the water evaporates make the Dead Sea about nine times as salty as the oceans. Animal and plant life cannot exist in this high a concentration of salt, so the Dead Sea was given its name long ago because there was no evidence of any forms of life in it. There are tiny microbes living in the Dead Sea, but their existence was unknown before the 1900's.
Possible but then impossible. For earth to also survive is by water. If no water, there becomes dehydration. With dead land for instance; Is dead land because there was no water.
Yes because there is so much salt in dead sea water the water is denser making you relatively lighter compared to normal water.
Salt does make a difference in buoyancy but if there is no salt then you shouldn't sink to the bottom. Your head will go under. Every object has some degree of buoyancy in water. Some have enough so that they float, others do not. _______ Actually, the Dead Sea is not 'buoyant'. Buoyancy is a property of a solid object you put in the water. The salinity of the dead sea increases the specific gravity of its water. Specific gravity is to liquids as density is to solids. So the water of the Dead Sea has a very high specific gravity.
When a fresh body of water reach below a pH level of 4.o, uninhabitable by even frogs, it is considered dead.
If it is a fresh water river. The water may be polluted. If you see any dead fish floating down the river, it's probably not a great idea to drink out of it. Otherwise it should be good enough.
To revive an orchid with dead roots, you can trim off the dead roots and repot the orchid in fresh, well-draining orchid mix. Ensure the orchid receives proper light, water, and humidity to encourage new root growth.
Jordan river
The waterway that extends north of the Dead Sea is the Nile River. The northernmost waterway that bounded the Mesopotamia region is the Euphrates River.
The Dead Sea does not have any tributaries that flow directly into it. Instead, it primarily receives water from the Jordan River, which is its main inflow. Additionally, various small streams and seasonal wadis contribute some water, but these are not considered significant tributaries. Due to high evaporation rates, the Dead Sea's water levels have been declining, which affects the surrounding ecosystem.
An estuary is usually considered the mouth of a river where it enters the ocean and thus marine and fresh water mix. Though not all lakes are fresh water, where rivers enter into a lake both the river and lake water are most likely fresh water. The Dead Sea, The Great Salt Lake, the eastern portions of Lake Balkash, and the Salton Sea are all terminal bodies of water into which rivers flow, bringing some fresh water to these otherwise saline (very salty) lakes. The lake are saltier because they are in a desert where the evaporation of fresh water leaves behind salts.Estuaries, on the other hand, have some salt water (more saline water especially in saltier lagoons) as they are where rivers meld into the ocean. Oceans are usually a bit more than three percent salt (33 parts per 1000) water and in the estuary or river mouth, the waters form a boundary at the mixing zone where lighter fresh water flows out above the dense salt water below.

The Nile is not a 'dead river' however, any river would be considered a 'dead river' once it was incapable of sustaining any form of life such as fish and aquatic plants. This would usually happen because of major pollution taking all the oxygen from the water.
There are actually "two" Jordan rivers: the one from the slopes of Mt. Hermon to the Kineret (Sea of Galilee), and its continuation from the Kineret to the Dead Sea. The main importance of the Jordan River is in its first portion, which is the Kineret's major supply of fresh water. Because the country of Jordan is arid, it (like Israel) sees the river as one of its water-sources. Also, the river is Jordan's western border. For Syria, besides fresh water, the river has the significance that some of its northern stream-tributaries used to be within the borders of Syria and are now in the Israeli Golan Heights.
To revive a schefflera plant, ensure it receives proper sunlight, water it consistently but avoid overwatering, and consider repotting it with fresh soil if needed. Trim any dead or yellowing leaves, and fertilize it occasionally to promote growth.
