Dawn recorded her measurement of the mass of a sample of leaves as 13 grams (g). four of her classmates measured the same sample and recorded the following data: 30 g, 31 g, 29 g, and 30 g. all students used the same balance during the same class period. dawn’s data are most likely inconsistent due to human error. biased procedures. broken instruments. accurate measurement.

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.
