Saline solutions have the same or close to the same amount of salt as our blood does, so we get the amount of salt needed for our bodies. During blood loss, you lose the salt you need, so they're basically adding it back in with the saline solution, making your electrolyte balance go back to normal level. It also gives us the right amount of water to keep us hydrated.
Answer:
They are genetically identical to the parents and only differ if a genetic mutation occurs.
Sexual reproduction involves two parents and produces offspring that are genetically unique.
The greater the genetic variation, the better change that an individual in the population have a favorable gene that can help survival. Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population.

Explanation:
Let's assume that the gene coding for tongue rolling is encoded by letter T.
The allele for tongue rolling (T) is dominant over the allele for inability to roll the tongue (t).
In a cross between two homozygous dominant individuals (TT) i.e. they have the same dominant allele in their genotype and hence, they can both roll their tongues.
(See attached image)
The cross will produce four possible offsprings, in which all will possess a homozygous dominant genotype i.e. all will be phenotypically able to roll their tongues. Hence, in the case of the child, the child will be able to roll his tongue.
The probability or chance that the child will be unable to roll his tongue is 0. Since there is none.
