Questions and answers

  1. Easy How do ships calculate how deep the ocean is using sound waves?

    Ships measure the time it takes for a pulse of sound to bounce off the seabed and return.

  2. Easy How do bats avoid obstacles while flying in pitch darkness?

    Bats use echoes from their high-frequency calls to locate objects.

  3. Easy Which sense organ helps a migrating robin detect Earth's magnetic field?

    Specialized light-sensitive proteins in the robin's eyes allow it to sense the planet's magnetic field.

  4. Medium Why are juvenile basilisk lizards much better at running across water than fully grown adults?

    Adults are too heavy, and their muscle power cannot generate the necessary speed to slap the water effectively.

  5. Medium What evolutionary development allowed elephants to accumulate an unprecedented number of olfactory receptor genes over time?

    Repeated duplication of existing scent genes occurred as their elongated trunk evolved into a primary sensory tool.

  6. Medium Why do scallops have dozens of tiny eyes lined along the open rim of their shell?

    Their numerous perimeter eyes detect nearby motion and approaching predators from almost any angle so the scallop can escape.

  7. Hard Why did researchers Donald Griffin and Robert Galambos introduce the specific term echolocation in 1944 rather than relying on existing acoustic navigation terms?

    They wanted a term clearly describing animal navigation via self-emitted vocal sounds and returning echoes rather than passive listening.

  8. Hard Among a human, a dog, a bat, and a greater wax moth, which organism can detect the highest sound frequencies?

    The greater wax moth can detect the highest sound frequencies among the listed organisms.
