A. The fish's brain would not be able to send information to the rest of its body.
B. The fish would not be able to send useful information from its eyes to its brain.
B. The fish would not be able to send useful information from its eyes to its brain.
How does a Tokay gecko usually see, and why does more light make it hard for it to see?
A. The gecko sees well in bright light, but too much light can overwhelm its vision
B. The gecko's eyes are adapted to dark, and too much light can confuse it
C. The gecko uses sound to see, and light does not affect it
D. The gecko can only see during the day, and light does not matter at night
B. The gecko's eye are adapted to dark, and too much light can confuse it
Which claim about a night and day hunter's light sensitivity is most accurate?
A. The night hunter has low sensitivity light receptors while the day hunter has high sensitivity receptors.
B. The night hunter and the day hunter both have low sensitivity light receptors.
C. The night hunter and the day hunter both have high sensitivity light receptors.
D. The night hunter has high sensitivity light receptors while the day hunter has low sensitivity receptors.
D. The night hunter has high sensitivity light receptors while the day hunter has low sensitivity receptors.
Worms are covered in tiny hairs that help them understand what their environment looks like because they don't have_________
eyes
How something works is called its __________?
Explain how the brain and eyes work together when an animals sees a predator.
When an animal sees a predator, the eyes send the image to the brain, which then decides how the animal should react, usually by running away to safety.
True or False
Animals that see best at night have low light receptor sensitivity.
False, animals that can see at night have high light receptor sensitivity
Why is the student's claim that light is not necessary to see objects inaccurate?
A. Light is not necessary to see objects and when it is dark outside.
B. The eyes work with other parts of the brain to see objects when there is no light outside.
C. Even the smallest amount of light that is outside at night reflects off the surface of an object, and then the eyes can see the object.
D. The eyes convert light into an object that can be seen against shadows.
C. Even the smallest amount of light that is outside at night reflects off the surface of an object, and then the eyes can see the object.
What is the definition of survive?
To stay alive
Light needs to ____________ off an object and get to the eye for an animal to see the object.
reflect
Describe how a Tokay gecko uses its eyes to see its prey.
A Tokay gecko uses its eyes to detect movement and shape of its prey. The brain processes this information so the gecko can react quickly and catch the prey.
Describe the path of light going into the eye.
Light comes from a source and first enters the pupil. Then light goes to the light receptors. Next, the light receptors lead to the optic nerve that sends information to the brain for the brain to form an image.
How does a shrew's nose and hears help it survive in it's environment?
The shrew's nose picks up the scent of food, which sends signals to the brain. The brain processes this information and triggers the shrew to move towards the food. Its ears help it detect any nearby predators.
