How does Dr. Laurel Symes describe the process of male tree crickets creating vibrations?
Dr. Laurel Symes explains that male tree crickets produce vibrations by rubbing their wings together.
What is the role of the cochlea in the hearing process?
a) It amplifies sound waves
b) It processes sound signals and sends them to the brain
c) It protects the eardrum from damage
b) It processes sound signals and sends them to the brain
According to Dr. Laurel Symes' research, what influences the rate at which male crickets rub their wings together?

b) The time of day
c) The species of cricket

Can you explain how larger animals such as mammals produce sound?
Larger animals, such as mammals, produce sound by sending air through their vocal cords, which causes the cords to vibrate and create sound.

c) Antennae
What is the primary difference between insect and mammalian ears?
a) Mammalian ears are smaller
b) Insect ears are more complex
c) Mammalian ears contain hearing hairs
d) Insect ears are located internally
b) Insect ears are more complex
What advantage do insects gain from having specific ranges of hearing?
a) They can communicate with other species
b) They can filter out irrelevant noises
c) They can hear sounds from long distances
d) They can perceive sounds in multiple frequencies
b) They can filter out irrelevant noises
How do most mammals hear sound?
a) Through their skin
b) Using their eardrum, bones, and cochlea
c) By flapping their ears
b) Using their eardrum, bones, and cochlea
How do elephants interpret low, rumbling calls from a distance?
a) By flapping their ears
b) By sensing vibrations through the ground
c) By using their trunk to amplify sound
b) By sensing vibrations through the ground
What distinguishes the hearing mechanism of insects from mammals?
a) Insects have large external ears
b) Mammals have "hearing hairs" inside their cochlea c) Insects use their body to sense vibrations
c) Insects use their body to sense vibrations
How do insects perceive sound vibrations?
a) Through large and complex ears
b) Through small and simple ears
c) Through their mouths
d) Through their antennae

What is the similarity between the buzzing sound of insects and the ringing of a guitar string?
Both the buzzing sound of insects and the ringing of a guitar string result from rapid vibrations.
How do insects perceive vibrations differently from mammals?
a) Mammals feel vibrations through hairs and appendages
b) Insects have larger ears for hearing
c) Mammals use antennae to sense vibrations
d) Insects have specialized hearing organs
a) Mammals feel vibrations through hairs and appendages
What role do vibrations play in the creation of sound in mammals like humans?
Vibrations play a crucial role in the creation of sound in mammals like humans by causing their vocal cords to vibrate when air passes through them.
What is unique about elephants' ability to hear low-frequency sounds?
a) They use their trunk to amplify sound waves
b) They conduct sound through their skin and bone
c) They have a special ear structure
b) They conduct sound through their skin and bone
What is one consequence of insects having specific ranges of hearing?
a) They can hear only loud noises

c) They can only hear other insects of the same species
d) They can hear sounds from long distances
c) They can only hear other insects of the same species
What does Dr. Laurel Symes' research suggest about the communication abilities of female crickets?
