PLEASE HELP!!!!!! Find out more about sound frequencies and write 1-2 pages about your discoveries. Did you know that some animals can hear sounds that we humans can't? Do some research on dogs, cats, bats, whales and dolphins (or any other animals you may be interested in) and find out what frequencies they can hear. Find out how they use sound. Do they use it for navigating? For gathering food? For other specialized tasks?
