lidiya [134]

From what we know, we can confirm that based on memory research, the best way for Vance to remember the new information is to get a good night's rest.

<h3>Why is it important to get a good night's rest?</h3>

Recent memory research has linked a good sleeping habit to widely increased memory performance. Sleeping helps the brain to strengthen the vividness of memory and the brain's ability to more easily recall that information.

Therefore,  we can confirm that based on memory research, the best way for Vance to remember the new information is to get a good night's rest.

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.

Answer:

A. The temperatures are too high.

Explanation:

A desert is a region with extremes of temperatures and little to no rainfall.

Organic matter are the remains of organisms that have died. They are a very important component of soils.

Where temperatures are very extreme, there would be little to no life. Only special organisms that have evolved to adapt will survive such region.

Due to the low amount of plant and animal lives owing from the high temperature of deserts, little to no organic matter forms.
