A girl received one recessive allele for blue eyes from her father and a recessive allele for blue eyes from his mother. Which of the following best describes the girl’s genetic type?

Well, since the girl got two recessive alleles from both her parents, she will have the genotype bb and blue eyes.

answer: c. two haploid cells

explanation:

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
