Answer:

Explanation:

Cs and Na are solids in room temperature while F and Xe are gases.

The number of electrons in the outermost shell of an atom will determine its reactivity. Out of the gases given Xe and F, F ( the most electronegative element) posses 5 valence shell electrons which makes it highly reactive while Xe which is a noble gas posses 8 valence shell electrons which makes it less reactive compared to many elements.

Answer:

Phenotypes of offsprings: Type A, Type B

Explanation:

This question involves a single gene for blood group in humans. The ABO blood group system consist of three alleles: A, B, and O. A and B are dominant over O but co-dominant to one another.

If a woman with type O blood (OO) has a child with a male with type AB blood (AB) i.e OO × AB, the following gametes will be produced by each parent:

OO - O

AB - A and B

Using these gametes in a punnet square (see attached image), the offsprings with the following genotyoes will be produced: AO (2), BO (2)

AO - phenotypically type A

BO - phenotypically type B

Hence, a type A and type B blood group offsprings will be produced.
