Answer:

The answer to your question is letter E. Nitrogen is much more electronegative than hydrogen.

Explanation:

Talking about bonding, we must know that there are two main types of bonds.

- Ionic bonds: these bonds are formed when we combine metal and a nonmetal and the electronegativity between these elements is higher than 1.7.

- Covalent bonds are formed when two nonmetals are combined. There are two kinds of covalent bonds:

a) Nonpolar, the electronegativity between the nonmetals is between 0 and 0.5.

b) Polar, the electronegativity between the nonmetals is between 0.5 and 1.7.

In this problem, the difference of electronegativity between nitrogen (3.04) and hydrogen (2.2) is 0.84, then this molecule has a polar bond.

Explanation:

in paulings scale hydrogen is 2.1 and nitrogen is 3...so

nitrogen is much more electronegative than hydrogen.

1. Which blood types are dominant?

marishachu [46]

Answer: 1). A and B are both dominant (because A and B are codominant to one another)

2). E. All of the above

Explanation:

1). From the image above, A and B are both dominant because they are equally expressed when they occur in a pair (when they occur as blood type AB), also they are dominant because each of them expressed itself when it occurs in a pair with a recessive allele (IAi and IBi).

2). The children of a father with A blood and a mother with B blood will have all the four blood types: A, B, AB, and O. If each parent has a recessive allele, that is if each parent is heterozygous for his/her blood type (IAi for the father and IBi for the mother), the cross between them will produce all the four possible blood types.
