Answer:
The formula for every water molecule is .
Explanation:
We have to find what is true for every water molecule.
We know that a water molecule is made by two atoms of hydrogen and one atom of oxygen. The ratio of hydrogen and oxygen in a water molecule is 2:1.
We know that every water molecule is same.Therefore, every water molecule is made by two atoms of hydrogen and one atom of oxygen.The ratio of hydrogen to oxygen in every water molecule is same. Therefore, the ratio of hydrogen to oxygen in every water molecule is 2:1.
The force that binds one water molecule to other water molecule is hydrogen bonding.In hydrogen bonding , a hydrogen atom is linekd with high electro- negative atom such as flourine, oxygen etc.\
Therefore, in water molecule a hydrogen atom is linked with oxygen atom of other water molecule. Hence, hydrogen bonding occurs.

Answer:
25%
Explanation:
Let's assume that the recessive allele "p" imparts diseased conditions in the homozygous genotypes. The genotype of each of the carrier parents would be "Pp". A cross between Pp and Pp would produce progeny in the following phenotype ratio=
Pp x Pp= 3/4 Normal : 1/4 Affected.
Therefore, there are 1/4 or 25% chances for this couple to have a child with PKU.
