Using powerful new sequencing technologies, investigators can now catalog every rna molecule made by a cell and determine at what quantities these rnas are present. the graphs show the relative quantities of two different mrnas—one transcribed from gene x, the other from gene y—in two different cell types. which most likely encodes a housekeeping protein?

choose one:

a. both genes
b. neither gene
c. gene b only
d. gene a only

Which process must a cell undergo top identical cells at the end of cell division

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.
