Decreased levels of carbonate.
Answer:
You can conclude that the species is polygamous.
Explanation:
The answer is O.
Since blood type A and B are codominant, it means that the people who have blood type AB only have genes of A and B. They do not have the gene for blood type O.
We can be sure that the child will not have blood type O by constructing a Punnett square. We can list all the possible genotypes thus predict their phenotypes. The capital letters represent the genotypes of parents, while others are the positive genotypes of offsprings.
From this, we can see that the only possible blood types their child could have are A, B, or AB. So, O is not possible.
Bacteria help the nitrogen change between states so it's able to be used. Different bacteria help it to change states so it can be absorbed by plants when nitrogen is absorbed by the soil.
