Living organisms make and use three main types of ribonucleic acids (rna) for their biological functions: ribosomal rna (rrna) messenger rna (mrna) transfer rna (trna) part a - properties of rna sort each description by the type of rna it describes. drag each item to the appropriate bin.

Based on the observation that only male crickets produce a song, you hypothesize that a male's song is a form of communication to potential mates. you set up a simple experiment to test this hypothesis. in the laboratory, you place a male snowy tree cricket in enclosure a, which is adjacent to enclosureb. in enclosure b, you place other insects, one at a time, and observe their responses to the male's song. the enclosures are designed so that the two insects being tested cannot see or smell each other, but sound is transmitted from enclosure a to enclosureb.
