Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.
When injected, benzedrine, dexedrine, and methamphetamine increase the release of serotonin, norepinephrine, and dopamine in the brain. Benzedrine, dexedrine, and methamphetamine are examples of amphetamines. They are stimulants, which speed up the messages travelling between the brain and the body. They may be used to treat attention deficit hyperactivity disorder.
Answer:
Dispersion of white light by a prism
Explanation:
When white light is passed through a prism, the white light separates into its component wavelengths which are:
Red
Orange
Yellow
Green
Blue
Indigo
Violet
Together, all of these wavelengths constitute the spectrum of white light.
Hence, the dispersion of white light shows that each color of visible light has a specific wavelength.
Newton's Second Law of Motion says that acceleration happens when a force acts on a mass. Riding your bicycle is a good example of this law of motion at work.Your leg muscles pushing pushing on the pedals of your bicycle is the force. When you push on the pedals, your bicycle accelerates.
Answer: Light Refraction
Explanation:
Light rays travel in straight lines. When they strike an opaque surface, the rays bounce, and light is reflected back to your eye so that you see an image. When light strikes a transparent object, some of the light passes through. If that light strikes the object straight on, it continues to travel in a straight line. If the light enters the transparent object at an angle, though, it changes direction, bending.This bending of light is called refraction. Refraction occurs because light entering an object slows down. When it enters at an angle, one side of the light ray enters before the other, slowing down first.Looking from above, an object under water appears larger than it does in air. It's not that the image the light gave our eyes is bigger. It's that the image is actually closer to our eyes, since the light is not passing straight down, but is instead bending relative to the water's surface. Light passing straight down would be perpendicular to the water's surface, like the vertical line on the letter T.
