Answer:
G and K
Explanation:
Crossing-over is a genetic phenomenon that occurs in meiosis, specifically, Prophase I. It is when chromosomal segment (genes) are exchanged between non-sister chromatids of homologous chromosomes. Crossing-over occurs only to genes that are UNLINKED i.e. genes located on different chromosomes or far apart on the same chromosome.
This unlinked genes are said to have the highest RECOMBINATION FREQUENCY. Crossing-over allows genes on the same chromosome but far apart from each other, assort independently, which allows alleles to be recombined on the same chromosome. This phenomenon does not occur to genes that are close on the same chromosome as they will be inherited together as a unit.
In this case, G and K are the farthest apart, hence, they will have the highest RECOMBINATION FREQUENCY i.e. the likelihood for homologous crossing-over to take place during meiosis.
The purpose of meiosis<span> is to reduce the normal diploid cells to haploid cells, called gametes.

Answer:
Explanation:
Think about what a school would have/use that has the most environmental impacts. I think of energy and waste from trash. To counteract these they could install a cleaner method of getting energy like solar panels and for the trash they could implement a recycling program
Answer:
pharynx, larynx, trachea, bronchi
Explanation:
During the inhalation through the nose or mouth the air first enters the "pharynx" which is also called as throat,
then the air moves towards the "larynx" . Is a passage between the pharynx and the trachea
Through larynx the air then moves toward the "trachea". It is passage connecting the larynx and the bronchi
and then the air inhaled reaches to the "bronchi" of lungs.
hence, the correct order is "pharynx, larynx, trachea, bronchi"
Explanation:
True, if sedimentary rock is exposed to energy from the sun at Earth's surface for a long enough time, it can melt into liquid rock and form igneous rock. No, igneous rock forms under Earth's outer layer due to energy from Earth's interior, but sedimentary rock is only at Earth's surface.
