The statement 'cell death normally does not occur unless there has been an injury to the cell' is false.
A cell can be described as the basic building block of life. All living organisms are known to be made of cells.
There are various reasons that a cell might die. A cell might die when its function is over. A cell might also die for the formation of other structures in the body. For example, the formation of an outer layer of the skin requires dead cells. A cell might kill itself if it has no use or finds that it has been invaded by an antigen.
Hence, the statement that cell death occurs only due to injury is false as cell death can occur due to various other reasons.

It is a process that causes rock to break into little pieces.
Answer: The reason why pestisides are found in our water is because the government and farmers put some type of chemical on the plants and in the water so animals like worms or bugs dont drink or eat our food and water supply.
PROS: It dissolves in water and lowers the freezing point of water so a lower temperature is required for ice to form. This makes the road less treacherous for vehicles. Road salt is usually cheap and readily available. Since salt is already a constituent of sea water, it does not cause pollution when washed away.
CONS: Salt dissolved in water is corrosive to metal. A metalled road surface may eventually be attacked by the corrosive, leading to damage of the surface. The salt solution is splashed on to the bodies and into the engine parts of vehicles and, unless properly protected, the metal parts of the vehicle will become corroded. Salt solution is a good conductor of electricity so it could under certain circumstances affect the electrical circuits within vehicles. When the salt solution dries out it leaves a deposit of white salt on the surface. The spreading of road salt is often carried out by specially equipped vehicles, so there is a cost incurred in salt spreading. Usually salt is mixed with grit.
