Adding any nonvolatile solute to water will lower the freezing point and raise the boiling point .... but not by very much.

There is a myth that adding a bit of salt (NaCl) will raise the boiling point and cause to food to cook faster. The problem is that the small amount of salt added to boiling water by the average cook will have a negligible effect on the boiling point of the water. So why is salt added to boiling water? To make whatever is cooking in the water a bit salty.

As for what happens.... Water boils when its vapor pressure is equal to atmospheric pressure. Adding salt decreases the vapor pressure of the resulting solution, which means that more energy is needed to force the solution to boil, and the boiling point is elevated.

Boiling point elevation is a colligative property and depends on the total number of particles in solution. The increase in boiling point, DT, can be calculated ...

DT = iKm ... where i is the van't Hoff factor, and indicator of how many particles come from a formula unit of solute. K is a constant. The boiling point elevation constant for water is 0.512 C/m. The symbol "m" stands for molality, a way of expressing concentration in moles of solute per kilogram of solvent.

How do genetics represent h dominant and Recessive allele?

A dominant genotype is represented as DD or Dd but with many different letters. The DD is a homozygous dominant, while the Dd is the heterozygous dominant. Recessive is always represented as dd or rr or whatever letter you want to use. It is always homozygous recessive. There can never be a heterozygous recessive.


What does dd mm yyy?

"dd mm yyy" is an incomplete date format. It seems to be missing the actual numbers for the day, month, and year. Typically, it should be written as "dd/mm/yyyy" or "dd-mm-yyyy" to represent the actual date.


If a dog's genotype is Dd if it has a disease what genotype does another mate have to have in order for have of the puppies to not have a disease?

There is not really enough information in the question to answer it properly. You would need to know what trait the D and d stood for to give a proper answer.If the dog's genotype is Dd and it has the disease, this suggests that the disease is caused by a dominant allele. A healthy bitch would have the genotype dd and half of her pups would have the disease. There is no mate which would produce all heathly pups.If the dog is symptom free then the disease is caused by a recessive allele. In which case the dog should be matted with a dog with the genotype DD to have 100% symptom free pups. Mating Dd to Dd would give 75% symptom free pups and 25% sufferers. Mating the Dd dog to a dd dog would give 50% disease free pups and 50% sufferers.


A man who has dystonia marries a woman who doesn't one of their children has the condition what are the possible genotypes of the man and woman?

Assuming the dystonia is hereditary and is a recessive gene which will be called "d" for simplicity, that means the man must be "dd" and the woman is "Dd". This is the only way they could have a child who is "dd" like the father, but not the mother.
