<span>Each RNA nucleotide consists of three parts: a sugar, a phosphate group, and anitrogen-containing base. The four RNA bases are adenine, uracil, guanine, andcytosine—often referred to as A, U, G, and C. RNA shares three bases in common with DNA: adenine, guanine, and cytosine. Instead of uracil, DNA contains thymine.</span>

Explain the role of bacteria in the nitrogen cycle
Oksanka [162]

Bacteria is important because this bacteria binds hydrogen molecules with the gaseous nitrogen to form ammonia in the soil.  During assimilation, or when plants take up nitrates from the soil, bacteria aid in the process with the plants in making ammonia. Animal wastes is also a major place where bacteria thrives and produces ammonia. The process in which assimilation occurs in plants, and then bacteria converts the nitrates to ammonia is called ammonification.  From the conversion of ammonia to nitrites, bacteria also aids in this process called nitrification. The nitrifying bacteria mostly present in soils, oxidize ammonia into nitrites, and from nitrites to nitrates.

Finally, the process of denitrification also has bacteria present to aid in converting nitrates back into a gaseous form of nitrogen in the atmosphere.

A "mystery molecule" was isolated in a laboratory and scientists found that the molecule readily crossed artificial membranes. W
Arlecino [84]

<u>Answer</u>:       D. calcium chloride

<em>Calcium chloride molecules can be ruled out as the mystery molecule</em>

<u>Explanation:</u>

<em>Artificial membranes are also called as the synthetic membranes.</em> It is created synthetically for the <em>special separation purpose in the laboratory. </em>

It is used to separate large molecules like <em>solid particles and big biological molecules like protein, DNA. </em>

They are produced from organic materials. <em>Calcium chloride contains the chloride ion and calcium ion,</em> as the chloride ion easily passes the artificial membrane so we can term <em>calcium chloride as the mystery membrane that passes the artificial membrane easily.</em>
