An american cockroach (periplaneta americana) can begin to turn away from approaching danger, such as a hungry toad lunging toward it or a flyswatter wielded by a cockroach-loathing human, in as little as a hundredth of a second after the air pushed in front of the moving object reaches the roach’s body. a cockroach has very sensitive wind sensors on its cerci, which are small appendages at the end of its abdomen. one cercus points slightly to the right, the other to the left. use what you know about moth orientation to bat cries to suggest how this simple system might provide the information the roach needs to turn away from an attacking toad, rather than toward it. how might you test your hypothesis experimentally?

The roaches antennas

Explanation:

the roaches antennas sense movement from far so the antennas sense when the roach is in danger their for it moves away not towards it.

human didn't come from monkeys man i hate these stupid teachers

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
