Question 1

How does an insect such as a moth or cricket detect sound?

Accepted Answer

D

Question 2

What does an invertebrate statocyst contain, which surrounds movable elements, so that changes in body position move the latter and thus trigger an action potential?

Accepted Answer

Invertebrate statocysts contain sensory hair cells that surround statoliths. When the body position changes, the statoliths move, bending the sensory hair cells and triggering an action potential.

Question 3

Where is fluid found in a healthy human ear?

Accepted Answer

A

Question 4

Which of the following comprise a fish's lateral line, which allows them to detect vibrations and water currents?

Accepted Answer

Neuromasts are sensory organs found in fish's lateral line. They help in sensing vibrations and water currents. Stereocilia and statoliths are structures found in the inner ear of fish and are not associated with the lateral line. Statocysts are sensory organs found in invertebrates such as jellyfish and are not found in fish.

-In the figure, which number identifies the...

Question 6

Sensory input from the eyes and ears travels in neurons to the brain. Why are the different stimuli perceived as light and sound?

Accepted Answer

Different types of sensory information are processed in distinct regions of the brain, allowing the brain to interpret them as different senses such as light and sound.

Question 7

Mechanoreceptors for touch and pressure are located in all of the following locations in the vertebrate body EXCEPT which?

Accepted Answer

Mechanoreceptors for touch and pressure are not located in bones.

Question 8

Which structures are used by many aquatic invertebrates to perceive changes in their body's position and orientation?

Accepted Answer

Statocysts are fluid-filled structures that contain small sensory hairs and mineralized crystals called statoliths. When the animal changes its position or orientation, the statoliths move, bending the sensory hairs and triggering nerve impulses that inform the animal of its new position. Otoliths and saccules are also sensory structures used for perceiving balance and hearing in aquatic vertebrates, and stereocilia are hair-like structures found in the inner ear of many animals that convert mechanical vibrations into electrical signals.

Question 9

-In the figure, which number identifies the structure that vibrates and bends the sensory hairs?

Accepted Answer

The stapes (3) is the smallest bone in the body and is located in the middle ear. It vibrates and bends the sensory hairs (4) in the inner ear, which converts sound waves into electrical signals that are sent to the brain.

Question 10

How can organisms perceive different intensities of a stimulus?

Accepted Answer

The answer of How can organisms perceive different intensities of...

Question 11

Where is the tympanic membrane in humans?

Accepted Answer

The tympanic membrane, also known as the eardrum, is located between the ear canal and the middle ear's cavity. It separates the outer ear from the middle ear and plays a crucial role in transmitting sound waves to the inner ear.

Question 12

If a fish loses one of its sensory structures, it will remain unable to school. Which structure, if lost, would render a fish unable to school?

Accepted Answer

The lateral line is a sensory structure in fish that allows them to detect movements and vibrations in the water around them. This sense is crucial for fish to navigate and school effectively. If a fish loses its lateral line, it will be unable to sense the movements of other fish and will not be able to coordinate its movements with the rest of the school. Therefore, the loss of the lateral line would render a fish unable to school.

Question 16

Which of the following is a feature of sensory adaptation?

Accepted Answer

Sensory adaptation is the phenomenon where sensory receptors become less sensitive to constant or unchanging stimuli over time. As a result, it decreases our sensitivity to constant stimuli and increases our sensitivity to changes in stimuli. This applies to all types of sensory receptors, not just pain receptors. Therefore, the best choice is D.

Question 17

Bats use high ultrasonic sounds to perceive their environment much like humans use radar. What is this process of detecting objects called in animals?

Accepted Answer

The process of detecting objects using high-frequency sound waves, as done by bats, is known as echolocation.

Question 18

What are stretch receptors?

Accepted Answer

Stretch receptors are also known as muscle spindles. These sensory receptors are found in muscles and respond to changes in muscle length and rate of change, providing information about muscle position and movement.

Question 19

How does an earthworm detect sound?

Accepted Answer

Earthworms do not have ears or specialized tympanic membranes. Instead, they detect sound through general mechanoreceptors on their skin. These mechanoreceptors are sensitive to vibrations and changes in pressure, allowing the earthworm to detect the movements of predators and other nearby animals.

Question 20

-In the figure, which number identifies the structure that vibrates and directly creates the pressure waves in the cochlea's fluid?

Accepted Answer
