Glucose and fructose are monosaccharides that have the same chemical formula, C6H12O6. However, they do not chemically react the sam. Which of the following generalizations can explain this? Monosaccharides serve different cellular functions, and they are only involved in reactions in which they are needed.
The atoms of monosaccharides are arranged differently, and the different shape gives each monosaccharide unique properties.
Monosaccharides have different properties, but the disaccharides they form when combined with other molecules will have the same properties.
The atoms of monosaccharides are arranged similarly, but the monomers from which they are formed have different properties.

Astudy by solloch and et. al., in 2017, gives the map above which shows the frequency of alleles with a ccr5-delta32 mutations over 87 different countries. this mutation deletes the presence of a co-receptor (ccr5) on the outside of human t-cells (lymphocytes). some viruses, such as the one responsible for the black death and human immunodeficiency virus (hiv), require this receptor for attachment to host cells during the infection process. the black death was an epidemic that passed over northern europe during the 14th century killing nearly 60% of europeans. according to this information, which explanation best explains why northern europeans show a greater immunity for hiv than some other parts of the world?
