Concept explainers
The eyes of vertebrates and cephalopods are similar in structure and function. A difference between the vertebrate eye and the cephalopod eye is that the vertebrate eye has:
a. an iris surrounding the pupil, whereas in cephalopods the pupil surrounds the iris.
b. a lens that changes shape when focusing, whereas in cephalopods the lens moves back and forth to focus.
c. a retina that moves in the socket when recording the image, whereas in cephalopods the retina changes shape when stimulated.
d. a pupil that shrinks in size in bright light, whereas cephalopods have a pupil that enlarges in bright light.
e. retinal synthesized from vitamin A, whereas cephalopods lack retinal.

- Which of the following is TRUE about cone cells? a. The three types of cones that humans have are called Q-cones, R-cones, and S-cones b. There are no cones at all in areas important for peripheral vision c. There are more cones than rods in areas of the retina that are important for peripheral vision d. There are no cones where the optic nerve leaves the eyeballarrow_forwardVision is a complex process. The human eye has many structures that contribute to vision. Which of the following statements describing the structures involved in the process of vision is NOT correct? a. Ciliary muscles change the shape of the lens to focus both near and distant objects. b. The cornea and lens bend light to focus the image on the retina. c. The iris relaxes and contracts to protect the retina from excess light. d. Lenses move forward or backward to control the amount of light striking the retina.arrow_forwardFor each of the following, match the pattern with its description. Not all terms will be used. Although the eyes of the octopus and vertebrates have evolved entirely independently, each has a retina, cornea, iris, lens, and a fluid-filled interior. These similarities of structure, despite different origins, provide a classic example of .... Insects and birds are far removed from one another, yet at a glance it is difficult to tell the difference between a humming bird and a humming moth. Both are the same in size, and both live off nectar in flowers, and hover in flight. This is a classic example of.... The apple maggot fly once infested the fruit of a native Australian hawthorn tree. In the 1860s some maggot flies began to infest apples. They multiplied rapidly because they were able to make use of an abundant food supply. Now there are two distinct species, one that reproduces when the apples are ripe, and another that continues to infest the native hawthor tree. This is an example…arrow_forward
- Answer the following questions in reference to the five eye structures listed below. This structure is found in the compound eyes of insects but not in the eyes of vertebrates. a. cornea Cephalopods use this structure to produce a sharply defined, detailed image. b. lens C. camera eye vThis structure forms the transparent front of the eye. d. ommatidium This structure primarily acts to focus light waves. This structure acts to maintain the shape of the eye and to transmit light e. vitreous body to other structures.arrow_forwardRegarding the sensation of various species, which of the following statements is false? A. The eyes of honeybees transduce parts of the electromagnetic spectrum that are invisible to humans B. Bats ears transduce sound waves that humans cannot hear C. Research has shown that the human eye transducers all of the electromagnetic spectrum to the brain, but the brain is unable to perceive it. D. Sharks have special organs that can sense the bioelectric fields of other living thingsarrow_forwardOf the following statements about the human eye, which would Gould agree with the most? A. The eye has lost its purpose and it's obsolete. B. The eye is a perfect fine-tuned machine well suited to its purpose. C. The eye has a use, but it was not evolved for that use.arrow_forward
- Of the following statements about the human eye, which would Paley agree with the most? A. The eye has lost its purpose and it's obsolete. B. The eye is a perfect fine-tuned machine well suited to its purpose. C. The eye has a use, but it was not evolved for that use.arrow_forwardThe transduction process of converting light into neural signals sent to the central nervous system involves which of these steps? A. Bipolar Cells collect signals from Rods and Cones. B. The Optic Nerve carries signals about light from the Lateral Geniculate Nuclues to the Retinal Ganglion Cells. C. Retinal Ganglion Cells relay information to Rods and Cones. D. Light that reaches the eyes passes first through the Retina which focuses that light onto the Cornea.arrow_forwardWhat is unusual about the olfactory receptors? a. Olfactory neurons have more than one axon. b. Humans do not begin forming olfactory neurons until nearly 2 years old. c. We continue forming new olfactory neurons throughout life. d. An unusually strong blood–brain barrier protects olfactory neurons from damage.arrow_forward
- What do the sensory systems of annelids, mollusks, arthropods, and vertebrates have in common?a. They all use the same stimuli for taste.b. They all use neurons to detect vibration.c. They all have image-forming eyes that evolved independently.d. They all use chemoreceptors in their skin to detect food.arrow_forwardWhat is the function of the three ossicles shown in blue (10, 12, 13)? ear with labels colorful.png a. amplify the motion created by sound waves hitting the tympanic membrane (ear drum) and conveying that to the labyrinth's little oval window, causing fluid to slosh inside the cochlea B . move when the tympanic membrane (ear drum) moves, creating pressure waves in the middle ear that feed down into the pharynx and combine with sound wave information from our jaws C. When the tympanic membrane (ear drum) moves, their mechanoreceptors are activated to send neural impulses to the brain about the sound wave intensities (loudness) D. they equalize the pressure inside the ear to protect the delicate sensory cells inside the inner eararrow_forwardKip enjoys playing with sparklers on the 4th of July. He always loves watching a friend run with a sparkler and the momentary trail of light that seems to be left behind. Which aspect of our visual system best explains this trail of light? a. lateral inhibition b. microsaccades of the eyes c. persistence of vision d. achromatopsiaarrow_forward
