Answer:
Following are the solution to this question:
Explanation:
In a spindle in prophetic (mitotic apparatus) spindle, pulley and cellular membranes form at the kinetochore of metaphase genes intended besides separation of anaphase daughter chromosomes.
Even though the cycle of creation of the cells move towards opposite poles, microtubules gradually form a network between them, and its duplicate chromosomes would be later removed.
Symptoms usually appear 30–60 minutes after eating toxic shellfish and includenumbness and tingling of the face, lips, tongue, arms, and legs. There may beheadache, nausea, vomiting, and diarrhea.
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.
The cranial nerve that carries visual impulses from the retina to the brain is the: optic nerve.
