Answer:

A) One of her parents had at least one O allele.

Explanation:

Two alleles are inherited for blood type. Because the woman's son has the O blood type, we can tell that she inherited the B and O alleles. She would have needed to get the O allele from only one other parent. It could either be a recessive allele, like what happened with her son, or from a parent with type O blood altogether (two O alleles).

We cannot tell for sure what blood types her parents had because there are multiple ways to inherit a B and O allele. For example, one parent could have been type AB and the other could have been type O. So, we can only assume what one of her parents' alleles must have been.

A closed glass jar contains water vapor. The jar cools and liquid water begins to form. What will happen to the mass of the cont
Dmitriy789 [7]
It will stay the same. 

The mass isn't <em>going anywhere</em> (You did mention the jar was hypothetically and therefore hermetically sealed) 

The only thing changing here is the density of the water in the jar (whether it be vapor, liquid or otherwise)
as the temperature drops and the vapour becomes liquid, the water will be more dense. 

that's not saying that the weight won't increase as that is controlled by the force gravity exerts on the mass. (Hint: water is much more affected by gravity than air is)
