Scientists are interested in determining if selenium, from a nearby mine, magnifies in the tissues of fish living in a lake. Whi
kykrilka [37]

Answer:

The answer is A.

Explanation:

To test if the selenium from the mine has an effect on the fish living in the lake which i assume is close to the mine, testing the tissue of the fish from that lake and comparing it to the selenium levels of the fish from a nearby lake would be a testable hypothesis because there is a comparable aspect and there should be a difference in the numbers between the fish from the two lakes because of their distance to the mine.

I hope this answer helps.

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.
