In an experiment two beakers were filled with the same amount of oil. The beakers were labelled 'A' and 'B'. In beaker A 3 cm^3 of lipase was added. In Beaker B, 3 cm^3 of distilled water was added. The contents of each beaker were then tested for fatty acid every 15 minutes. llpase distilled water oil. Identify the objective of this experiment?
Beaker A was left to stand in few hours. Would any reaction continue to occur in beaker A as it left to stand?

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.
