What is low concentration of dye?
Answer: The correct answer will be option-at the bottom of the cup. Explanation: In the given figure, the mixing of the dye in water has been shown which shows that dye in water gets mixes slowly.
How do you determine concentration of a dye?
If the concentration of a solution is unknown, the concentration can be measured by determining the amount of light it absorbs (its absorbance, A) at a particular wavelength (λ), using a spectrophotometer. Absorbance and concentration, c, are directly related by Beer’s Law.
What do diffusion and osmosis have in common?
Osmosis and diffusion are related processes that display similarities: Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.
What similarities and differences can we observe from diffusion and facilitated diffusion?
In facilitated diffusion, the molecules can pass both in direction and opposite of the concentration gradient. Simple diffusion permits the passage of only small and nonpolar molecules across the plasma membrane. Facilitated diffusion permits the passage of large and polar molecules across the plasma membrane.
What is the similarities of simple diffusion and facilitated diffusion?
Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient. The difference is how the substance gets through the cell membrane.
What do active transport and diffusion have in common?
What do facilitated diffusion and active transport have in common? How are they different? They both change the concentration level inside and outside the cell. Active transport requires energy and moves low concentration to high concentration.
What is facilitated diffusion is it active or passive?
Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.
