1. easter egg coloring:

a blue food coloring tablet is placed in a cup of vinegar and water. after several seconds, the blue tablet will begin to dissolve and will eventually spread evenly throughout the liquid.
image: beaker, blue food color tablet, water and vinegar, arrows
a. the blue dye is traveling from a __ to a __ concentration.
b. identify the type of transport illustrated in this scenario:
c. does this movement of particles require energy?
for each scenario, answer the questions and draw an arrow to illustrate the movement of molecules.

Explanation:

Question 11

Diffusion is the movement of particles from high to low concentration until equilibrium (equal concentration on both sides) is reached. So the answer is "equilibrium is reached".

When a cell is in salt water (high solute outside), water leaves the cell via osmosis (movement of water across a semipermeable membrane from low to high solute concentration areas).

Moving from low to high concentration with the help of a protein (no energy for facilitated diffusion, but here the direction is low to high which is active transport? Wait, no—wait, the options: facilitated diffusion is passive (high to low with help), osmosis is water, passive transport is high to low, active is low to high. So if moving from low to high concentration, it's active transport. Wait, the question: "A cell moves particles from a region of low concentration to a region of high concentration by" — active transport requires energy to move against concentration gradient (low to high). So the answer is active transport.

Answer:

equilibrium is reached
