<span>The trick here is to understand the definition of each of the cellular transport or function mechanisms listed. These are some interesting (and strange) analogies!
Facilitated Diffusion
This is when a mechanism assists in diffusing (spreading) some material into an environment. The dog on the wagon going through a spring loaded door would shoot it out into the environment. This is an odd analogy but Point 3 would be the one.
Active Transport
Is when energy is expended to transport molecules somewhere against a concentration gradient or some other barrier. Examples include transporting molecules across a cell wall. The best analogy is the dog being dragged into a bathtub (Point 1).
Phagocytosis
This is when a larger cell consumes a molecule often like eating. This matches to point 2 - the child eating the doughnut.
Passive Diffusion
Is when a concentration of molecules naturally diffuse into an environment. This suits point 5 - the crowded room full of people.
Pinocytosis
Is the budding of cell membranes to consume liquid in the surrounding environment. I guess a woman drinking tea is the closest analogy listed (Point 4).</span>
2 is the answer I THINK look at other ones first
D= m/v
solve this formula to find v
by solving we get,
v = m/D
v = 13/19.3
v = 0.67 cm^3
Directional selection I'm pretty sure hope it helps!
Answer: you didn't state the answers to choose from so i"ll just list common organic molicules: nucleic acids, proteins, carbohydrates and lipids.
