As powerful as diffusion is, cells sometimes must move materials in the opposite direction—against a concentration difference. This is accomplished by a process known as active transport. As its name implies, active transport requires energy.

Dominant: the more common trait (brown hair)
Recessive: a trait that doesn't show up unless both parents carry it (blue eyes)
Co- dominant: both traits show up and co- exist (AB blood)
Incomplete dominance: when a dominant gene does not completely mask a recessive gene so they blend (pink flower)
Phenotype: physical trait- able to be seen (stripes on a zebra)
Genotype: genetic makeup of an organism - genetic trait
Hetrozygous: different (Bb)
Homzygous dominant: same and dominant (bb) and (BB)
Purebred: same as homzygous- has same alleles (bb) and (BB)
Hybrid: also known as heterozygous traits

The correct answer is: a. n+1, n+1, n-1, n-1
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during mitosis or meiosis. There are three forms of nondisjunction:
1. failure of a pair of homologous chromosomes to separate in meiosis I ,
2. failure of sister chromatids to separate during meiosis II, and
3. failure of sister chromatids to separate during mitosis.
As a consequence of nondisjunction abnormal chromosome numbers appears. If nondisjunction occurs during the meiosis I (anaphase I), this means that at least one pair of homologous chromosomes did not separate. The consequence is two cells that have an extra copy of one chromosome and two cells that lack that chromosome.
I think it is a sex cell (not sure)
