D. butterflies (they eat plants so they are a consumer)
A. The variables in the problem include the miles traveled, the cost to rent the car and the cost per mile traveled in the car.
b. The rate of change in the problem is the amount of payment that is expected per mile traveled.
c.The y-intercept is the total cost of the miles traveled without including the deposit.
d. A straight-line function will work for this problem, where y = mx + c.
m = $0.15, c = $25 and x = total miles traveled.
e. y = ($0.15)(1200) + $25
= $180 + $25
= $205
<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>
Selective permeable means it selects what goes out and comes into the cell. If the cell membrane wasnt selective then things could enter the cell and destroy it.
