Classification is the answer!
Answer:In a meiotic cell division, a diploid parent cell undergoes cell division to produce four haploid cells. Therefore, If three parent cells undergo meiosis, twelve haploid cells will be produced

Answer:
For a woman with type O blood and a man with type B blood, whose mother was of type O blood, the possible offspring will consist of B and O children.
Explanation:
Blood type is an inherited trait and is determined by the presence or absence of antigens A and B on the surface of the erythrocyte:
- <u><em>Blood type A</em></u><em> contains the antigen A and its genotype can be A|A or A|O.
</em>
- <u><em>Blood type B</em></u><em> contains the antigen B, whose genotype may be B|B or B|O.
</em>
- <u><em>Blood type AB</em></u><em> contains both antigens and a single genotype expression A|B.
</em>
- <u><em>Blood type O</em></u><em> lacks surface antigens, with a unique O|O genotype.
</em>
In the above case, the woman has an O blood type, whose genotype is O|O. The male must be heterozygous, since his mother was of blood type O, so his genotype is B|O.
To know the possible descendants of this couple, the crossing of the wolf alleles must be done:
Alleles B O
O B|O O|O
O B|O O|O
From where the probabilities of the offspring are obtained:
- Individuals with blood type B and genotype B|O 50%
- Individuals with blood type O and genotype O|O 50%
Therefore, from this crossing only descendants of individuals with blood type B and O can be obtained.
I think the correct answer from the choices listed above is option C. <span>Large doses of antibiotics given to fight an infection are likely to destroy bacteria that produce vitamin K. The digestive organ that would benefit from this bacteria would be the liver.</span>
