Answer:
- The blood group of the father must be B.
- The genotype of blood group would be .
- The Rh factor of the father can either be positive or negative.
- Thus, the genotype of Rh factor of father would be either Rr or rr.
Rh factor:
The phenotype of the mother Rh factor is positive. Thus, she can have Rr or RR as her genotype as positive is a dominant trait.
If the genotype of the mother is RR then all the offspring would be positive for Rh factor. However, one of the offspring is Rh negative, that means the mother must be heterozygous that is, Rr.
The genotype of the father can either be Rr or rr in order to produce offspring with positive as well as negative Rh.
Blood group:
The blood group of the mother is A. Thus, the genotype can either be or .
However, the blood groups of the children are O+ and B+.
Thus, the genotype of the mother must be heterozygous that is .
The blood group of the father must be B with genotype in order to produce offspring with blood group O and B.

Please, see the answer below.
Explanation:
The statement is inaccurate because a growing baby is not just a ball of multiplying cells that eventually grows large enough to form a baby.
<u>After fertilization and the formation of a single-cell zygote, the zygote continues to divide to form a ball of cells. However, at some points, the cells start to differentiate to give rise to various organs that make up the baby.</u>
<em>Without differentiation, there is not way the dividing cells will give rise to baby. Hence, a growing baby should be rather viewed as a ball of multiplying cells that eventually differentiates to form a baby.</em>
<span>The answer is d. front. A front is the narrow region between two air masses of different densities. The interaction of the air masses cause the mass that is less dense to rise. Once air rises it cools and condenses to form clouds and eventually leads to precipitation. Using cold fronts as an example, the denser mass of cold air forces the lighter warm air to rise. </span>
