6. Ribosomes contain a mixture of ribosomal RNA (rRNA) and ribosomal proteins. In most cases, any particular rRNA or ribosomal protein is represented once in a mature ribosome. Yet each type of rRNA is coded in eukaryotes by more than 100 gene copies per genome, and in contrast ribosomal proteins are single copy per genome (2 copies per diploid individual). Explain how eukaryotes can produce the same number of ribosomal RNAs and ribosomal proteins (needed in 1:1 ratio for ribosomes), given this disparity in gene copy number.

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.
