Which cell structure "speaks two languages"? Group of answer choices nucleus
ribosome
mitochondria
endoplasmic reticulum

Ribosome

Explanation:

Ribosome is a cell structure composed of RNA and proteins. They are the site of protein synthesis in the cells of living organisms, found either freely in the cytoplasm or attached to surfaces of endoplasmic reticulum organelle (RER).

According to this question, Ribosomes are the cell structures said to "speak two languages" because they are found in both prokaryotic and eukaryotic cells performing the function of protein synthesis (translation). Hence, ribosomes speak the prokaryotic language as well as the eukaryotic language.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
