It go's directly to the brain.......... :) ;)
Answer:
The correct answer is - Altimeter.
Explanation:
An altimeter is a sensor that is present in the new Fitbit. Altimeter measures changes in air pressure or barometric pressure. This sensor is used to count floors and use each 10 feet elevation as one floor.
Altimeter shows reading by the pressure of the air and every time the air pressure increases altitude is decreases and if air pressure decreases there is an elevation in altitude from sea level.
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.
The factors limiting the size of cells include: Surface<span> area to </span>volume<span> ratio (</span>surface area / volume<span>) Nucleo-cytoplasmic ratio. Fragility of cell membrane.</span>
