Organisms that live in deciduous forests have developed unique adaptations that aid in their survival. how are the bill and feet of the platypus specially adapted for survival in their environment?

a.
close the nostrils in its bill when diving underwater; pointed bill for spearing fish for food; detect vibrations of moving prey using the pads on their feet
b.
detect the electrical discharges of prey in the sand using small pits on its bill; crush the food with grinding pads on the top and bottom of its bill; webbed feet

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.
