Answer: Light goes into the eye via the cornea, it then pass through the pupil, the lens, the vitreous humor and finally forms an image on the retina.
Explanation:
Light goes into the eye via the cornea. The cornea is a clear, dome-shaped surface that covers the front of the eye.
From the cornea, the light passes through the pupil. The pupil regulates the amount of light passing through.
From the pupil, , light hits the lens. The lens is the clear structure inside the eye. It focuses light rays onto the retina.
Subsequently, light passes through the vitreous humor. A clear, jelly-like substance that fills the center of the eye. It helps to keep the eye round in shape.
Finally, the light reaches the retina where the image is formed the image is usually inverted. The retina is a light-sensitive nerve layer that is situated at the back of the eye.
The main function of the optic nerve is to carry the signals to the visual cortex of the brain. The visual cortex turns the signals into images.
<h2>b) option is correct </h2>
Explanation:
- Archaea are the closest modern relatives of Earth's first living cells
- Archaea are famous because of living in extreme environments
- If it’s super hot (more than 100° Celsius), freezing, acidic, alkaline, salty, deep in the ocean, even bombarded by gamma or UV radiation, there’s probably life there, and that life is probably archaeal species
- They’re also considered very resourceful
- Many forms of archaea can utilize totally inorganic forms of matter—hydrogen, carbon dioxide or ammonia for example—to generate organic matter themselves
