Sodium is not a macromolecule hence it does not contain any calories.
<h3>Does sodium contain calories?</h3>
The term calorie is a unit of energy. We often us the term to describe the amount of energy that is contained in each kind of food. The higher the calories, the greater the energy that the food contains.
Calories can only be contained by macromolecules such as proteins, carbohydrates, fats etc. Sodium is not a macromolecule hence it does not contain any calories at all hence the classmate is wrong.

Answer:
Explanation:
To interpret this pedigree, let’s start with information that we already know:
Brown is recessive, which means brown individuals must have the phenotype BB. In this pedigree, brown individuals are filled in.
Black is dominant, which means black individuals must have at least one B allele. Their phenotype could be either BB or BB. In this pedigree, black individuals are not filled in.
Figure 5 shows the same pedigree, but with information about the individual’s phenotype filled in.
The shaded individual, who is a brown female puppy, must have the phenotype BB. If she had any B alleles, she would be black because the black allele is dominant over the brown allele.
In order for the brown puppy to have the phenotype BB, she must have gotten two “b” alleles: one from each of her parents. We know that her parents are both black (because they are unshaped), which means they must have a least one “B” allele. This means that both parents must be heterogeneous: BB.
The three black puppies must have at least one “B” allele in order for them to be black in color. However, we can’t tell whether they are homologous dominant (BB) or heterogeneous (BB) since both of those phenotype would result in black color. One way to represent this on a pedigree is B-, meaning that the second allele could be either B or b.
Compounds have different conductivity because if they have the same meaning it wont be a other word. the compounds have to have a conductivity so there can be more meanings.
Mixtures are of 2 types.
1) Homogeneous mixture : In this type of mixture, the components of the mixture are present in the same phase. For example, Air. Air is a mixture of different gases which cannot be distinguished from each other.
2) Heterogeneous mixture : In this type pf mixture, 2 or more phases can be seen. The composition of the different components is not the same throughout the mixture.
Ex. mixture of oil and water. Here we can see 2 different phases one consisting of oil layer and the other made of water layer.
Salt water is a mixture of salt and water. Since salt is completely soluble in water, it creates a homogeneous mixture when mixed with water. We cannot distinguish salt and water once they are mixed.
To get fresh water from the salt water in the ocean, we can set up a simple distillation unit . In this, the salt water is heated to its boiling point and the vapors thus formed are allowed to cool which condense and create liquid water. This can be used as fresh water.
