Question 3

The adjustable opening in the eye,through which light passes,is the

Accepted Answer

The adjustable opening in the eye, through which light passes, is called the pupil. Option A, retina, is the layer at the back of the eye where the image is formed. Option B, iris, is the colored part of the eye that surrounds the pupil and controls its size. Option C, fovea, is a small depression on the retina that contains a high concentration of cones and is responsible for central vision.

Question 4

Which part of the electromagnetic spectrum are humans capable of detecting with the unaided eye?

Accepted Answer

Humans are capable of detecting light within the visible spectrum, which ranges from approximately 400 to 700 nanometers in wavelength. This includes colors ranging from violet to red.

Question 5

Briefly describe hyperopia and myopia and how these two common disorders of vision differ.

Accepted Answer

The answer of Briefly describe hyperopia and myopia and how...

Question 6

The conversion of energy from the environment into a pattern of responses by the nervous system (as opposed to interpreting that information)is called

Accepted Answer

The conversion of energy from the environment into a pattern of responses by the nervous system is called sensation. Perception, on the other hand, involves interpreting that information and giving it meaning. Assimilation and accommodation are terms typically used in the field of cognitive development.

Question 7

As light passes through the eye it is focused by the __________,which always focuses light in the same way,and the __________,which is flexible and enables focusing on objects at different distances by varying its thickness.

Accepted Answer

The cornea is responsible for the initial focusing of light, while the lens is flexible and can adjust its thickness to focus on objects at different distances. The other choices mentioned (aqueous humor, vitreous humor, fovea, retina, iris, and pupil) are all important parts of the eye, but they do not directly focus light.

Question 8

When you see something,

Accepted Answer

When light reflects off an object and enters your eyes, energy is absorbed by the cells in your retina, which then sends signals to your brain, allowing you to perceive the object. Therefore, energy comes from the object into your eyes.

Question 9

The interpretation of a pattern of stimuli from the environment (as opposed to mere conversion of energy into a pattern of responses)is called

Accepted Answer

The interpretation of a pattern of stimuli from the environment is called perception. Sensation refers to the process of converting energy (such as light waves or sound waves) into a pattern of responses in the nervous system. Assimilation and accommodation are terms used in the context of Jean Piaget's theory of cognitive development.

Question 10

When you see something,

Accepted Answer

When you see something, light energy enters your eye through the cornea and passes through the lens to reach the retina at the back of your eye. This energy is then converted into electrical signals that are sent to your brain, allowing you to perceive the image. Therefore, energy goes into your eye when you see something.

Question 11

Which of our senses detects part of the electromagnetic spectrum?

Accepted Answer

Our sense of vision detects part of the electromagnetic spectrum, specifically the visible light spectrum.

Question 12

What makes the electromagnetic radiation from 400 nm to 700 nm visible?

Accepted Answer

Our visual receptors, specifically the cones in our eyes, are adapted to respond to wavelengths between 400 and 700 nm. These cones contain specialized pigments that absorb light at specific wavelengths within this range, which triggers a neural signal to our brain that results in our perception of color.

Question 13

What happens during vision?

Accepted Answer

The answer of What happens during vision?
...

Question 14

Which of the following is necessary for vision?

Accepted Answer

Energy, in the form of light, enters the eyes and is detected by the retina which then sends signals to the brain to create visual images. None of the other choices accurately describe the process of vision.

Question 15

The continuum of all frequencies of radiated energy,from gamma rays to TV transmissions,is referred to as

Accepted Answer

The continuum of all frequencies of radiated energy, from gamma rays to TV transmissions, is known as the electromagnetic spectrum.

Question 16

The Gestalt psychologists described several principles of how we organize perceptions into meaningful wholes.Define the principles of (a)proximity, (b)similarity, (c)continuation,and (d)closure.

Question 17

The route of visual information from the visual receptors (rods and cones)to the brain goes from receptors to the bipolar cells to the ganglion cells through the optic nerve and finally to the brain.Describe in greater detail the route from the bipolar cells to the brain,specifically defining the ganglion cells and optic nerve.

Accepted Answer

The answer of The route of visual information from the...

Question 18

Our sense organs are packed with specialized cells called __________ that convert environmental energies into signals for the nervous system.

Accepted Answer

The given description of the specialized cells that convert environmental energies into signals for the nervous system clearly matches the definition of receptors. A stimulus refers to any form of energy or information that triggers a response in an organism, while adaptors and receivers are not specific terms used in the context of sensory organs. Therefore, the best choice is D, receptors.
