Unit 2 Chapter 4 2023-2024

A scientist observed a gecko and skink with their

prey. The skink reacted to its prey, but the gecko

did nothing. Which of the following best explains

why the skink had a reaction to its prey but the

gecko did not?

• The gecko was able to form an image of its prey,

  but the skink did not.

• The light bounced off of the prey into the gecko’s

  eyes, but the gecko didn’t react because it

  wasn’t hungry.

• Different animals have different ways of

  processing information, so they react differently

• Different animals have different light receptors

  with different sensitivities, causing them to react

  differently.

A mole is able to respond to

small amounts of information through its nose,

which means that its nose is ___________.

• big

• receptive

• nocturnal

• sensitive

Animals that look for food at night (nocturnal)

need to be able to see well in what type of light?

• LOW

• HIGH

Animals that look for food during the day (diurnal)

need to be able to see well in what type of light?

• HIGH

• LOW

A mole is able to respond to

small amounts of information through its nose,

which means that its nose is ___________.

• big

• receptive

• nocturnal

• sensitive

Alligators have highly sensitive skin. Parts of their skin have bundles of nerves that can sense very small changes in vibrations in their surroundings in and out of the water. These senses travel from the skin to the brain, and the alligator then uses these changes in vibrations to detect its prey. A student wants to make a model to test how alligator skin works. Which kind of model would best test this sensory system?

• Place a sheet of paper on a drum and hit

  the drum.

• Take leathery fabric and place it over a burner.

• Put rocks with smooth surfaces underwater

  and add ice cubes.

• Fill a balloon with water.

Which of the following best explains why a tarsier

cannot see during the daytime?

• The tarsier cannot tolerate the sun.

• The tarsier is nocturnal,

• The tarsier has high sensitivity light receptors,

  so there is too much bright light.

• The tarsier has low sensitivity light receptors, so

  it needs low light.

A squirrel looks for its food during the day since

the sun is shining bright and there is a lot of light.

Which type of light receptors does a squirrel

have?

• Squirrels have medium sensitivity light

  receptors.

• Squirrels have high sensitivity light receptors.

• Squirrels have low sensitivity light receptors.

• Squirrels have high and low sensitivity light

  receptors
