Which of the following statements are true for both the recrystallization and replacement modes of preservation? Choose one or m
vladimir2022 [97]

A similarity in both recrystallization and replacement modes of preservation is that delicate tissue and organs are not preserved.

<h3>What are recrystallization and replacement modes of preservation?</h3>

Recrystallization is a mode of preservation of fossils in which the internal structure of the fossils is changed by addition of more minerals to form larger crystal of the same material.

Replacement is a mode of preservation in which new material replaces the original material in the fossil.

In both methods of preservation, delicate tissue and organs are not preserved.

Therefore, a similarity in both recrystallization and replacement modes of preservation is that delicate tissue and organs are not preserved.

Light stimuli entering the eye encounter a series of structures while traveling to the brain. Place the structures in the correc
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.
