Answer:12.
Containing two complete sets of chromosomes, one from each parent.
Explanation: Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.
In a membrane, the tail of the phospholipids in one monolayer face the tail of the phospholipids in the other monolayer.

What is cell membrane?</h3>
- The cell membrane is a biological membrane that separates and protects the inside of all cells from the outside environment.
- It is also known as the plasma membrane (PM), cytoplasmic membrane or plasmalemma (extracellular space).
- The cell membrane consists of a lipid bilayer, which is made up of two layers of phospholipids interwoven with cholesterol (a lipid component) to maintain proper membrane fluidity at different temperatures.
- Furthermore, membranes are composed of membrane proteins, such as those that cannot be separated across the membrane and function as membrane transporters, and peripheral proteins that simply attach to the outer membrane of the cell and function as membrane transporters. enzymes to help the cell interact with its environment.
- The integrated glycolipids of the outer lipid layer perform a similar function.

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.
