Answer:
C. 100 percent
Explanation:
The woman is heterozygote: AO, while the man is homozygote: BB
By crossing the two:
AO x BB
A+B, A+B, O+B, O+B
AB, AB, OB, OB
We have two AB and two OB offspring. Both AB and OB are heterozygotes.
Thus all their offspring will be heterozygous.
<em>Had the question asked what proportion will be OB, the answer would have been 50%.</em>
Since the question asked, what proportion will be heterozygotes and not about the specific genotype, the correct answer is C. 100 percent

Answer:
Soil
Explanation:
Plants get their nitrogen from the soil. Although nitrogen is present in the air the structure of the molecule is strong and so would require large amounts of energy from the plant to break down.
The breaking down of nitrogen is a process called nitrogen fixation. Bacteria and archaea in the soil convert nitrogen into ammonia; breaking down the tough triple bond of nitrogen to be more readily absorbed by the plant.
