ch4aika [34]

Answer:

The correct answer is "1. cornea 2. retina 3. rods and cones 4. ganglion cells

5. optic nerve 6. thalamus 7. primary visual cortex"

Explanation:

Light must pass a series of structures for the brain being able to interpret the data that comes from the eyes. The order that light stimuli travels from the eye to the brain is as follows:

1. cornea

2. retina

3. rods and cones

4. ganglion cells

5. optic nerve

6. thalamus

7. primary visual cortex

Light enters trough the cornea, the transparent front part of the eye that covers two-thirds of its total optical power; then it goes to the retina which receives the image that could go to the rods or the cones (depending if the light is at low or high levels, respectively). Then, ganglion cells increase the rate of the impulse within the optic nerve, and finally thalamus passes the sensory signal to the primary visual cortex. In this area of the brain, the basic visual features are extracted and interpreted.

Elza [17]

"Dave", the feathered lizard fossil is thought of as a(n)<u> </u><u>homologous</u> species, or an organism that may represent a common ancestor shared by different but related lineages of organisms.

<h3>What is homologous evolution?</h3>

Homologous evolution is similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor.

Homologous structures include the human arm, a bird or bat's wing, a dog's leg, a dolphin or whale's flipper, and the wing of a bird or a bat. They are distinct and serve different purposes, although they are comparable and have similar characteristics. They are regarded as homologous structures because their underlying anatomies are comparable.
