C) Occurs in areas without soil.
Primary succession occurs in lifeless areas in which <span>soil that is incapable of sustaining life is formed due to lava, sand dunes, and </span><span>rocks left from a retreating glacier.</span>
The answer is a. to determine what sort of data table will be most useful.
Controlled experiment is used parallel with experiment in which some alteration of the subject is induced. This is because this way can be compared in treated and non-treated subject. When sort of data table is necessary, using the controlled experiment, it can be determined what sort of data table will be most <span>useful.</span>
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 correct option is D. This is because, mucus, inflammation and fever perform different functions in the immune system.The mucus membrane produces mucus which traps microbes. Inflammation refers to a localized tissue response which occurs when a tissue is damaged. Fever inhibits bacterial growth and speed up the rate of healing of a damaged tissue.
Answer: Carcinogens
Explanation:
Carcinoids refer to a specific type of slow growing tumor, tumors are the cancerous growths within a body, and sarcomas are tumors that occur in bones and soft tissues.
