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.

Answer: The correct option is A.
Explanation: there are two processes that takes place in cardiac cycle. These procesesss comprises of complete relaxation and contraction of both the atria and ventricles which usually last for about 0.8 seconds. Starting with the chambers in the diastole, blood flows passively from the veins into the atria and past the atrioventicular valves into the ventricles. Contraction begins in the atria following the depolarization of the atria and blood is pumped into the ventricles. The ventricles begins contraction by raising pressure within the ventricles.
A gene is a sequence of DNA that can be translated into a protein, an allele is a version of a gene. we have two alleles for every gene located on the same spot on different chromosomes
