Answer:

The correct answer is A. The two cerebral hemispheres are separated by the longitudinal fissure.

Explanation:

The longitudinal or intercerebral fissure is a deep cleft that divides the brain longitudinally into two hemispheres (the right and the left) joined together by the corpus callosum. Other fissures, such as the central sulcus, the lateral sulcus and the internal perpendicular fissure, divide each hemisphere into large cerebral lobes, which in turn have cerebral convolutions.

how does the random alignment of homologous chromosomes contribute to genetic variation in a population
SCORPION-xisa [38]

The assortment of homologous chromosomes during meiosis is random and generates genetic variation, the raw material for evolution.

During metaphase I of meiosis, homologous chromosomes are lined up at the equator plate of the cell in order to be separated (assorted) in anaphase I.

The separation of homologous chromosomes during meiosis I is random. Daughter cells receive unique gene combinations from an original parent cell.

Subsequently, haploid cells got from two successive meiotic divisions fuse during fecundation to form a diploid (2n) zygote.

During prophase I, non-sister chromatids interchange genetic material by a process known as recombination. This genetic process also increases genetic variation in daughter cells.

In conclusion, the assortment of homologous chromosomes during meiosis is random and generates genetic variation.

No, because it still codes for valine in this case, but if another nucleotide was changed such as GCA it would code for alanine instead.
