A scientist compares two cells, Cell A and Cell B, and notes that Cell B has a higher phospholipase C content than Cell A. Assuming no other factors are affecting this pathway, what can be said about the likely concentration of IP3 in Cell B compared to Cell A?
Phospholipase C will have no effect on the IP3 concentration.
IP3 will be in a higher concentration in Cell B.
IP3 will be in a lower concentration in Cell B.
IP3 will be in the same concentration in both cells.

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.
