Match the number with the letters correctly
(i will give the award)
1- a dog being dragged into a bathtub against its will
2- a child eating a doughnut
3- a dog pulled on a wagon through a spring loaded door
4- a woman drinking tea
5- a crowded roomful of people gradually standing up, wandering around, and leaving the room
a- pinocytosis
b- passive diffusion
c- facilitated diffusion
d- phagocytosis
e- active transport

Here are the following solutions:

1. E, because energy is needed to move the dog into the bathtub, like movement of particular molecule in the direction where it does not tend to move to, against the concentration gradient as in active transport.

2. D. I believe it's phagocytosis, as the depiction of the child eating the donut can be thought of as a macrophage or white blood cell engulfing a substance, which is encaptured by a vesicle.

3. C, I believe the dog being pulled by the wagon through the spring loaded door, can be thought of a particular ion and or larger molecule moving through the selectively permeable membrane via or through a channel protein as the spring loaded door.

4. A, again similar to the analogy of the child eating, the woman drinking can be analogous to a phagocyte, white blood cell, drinking and or taking in small amounts of fluid through vesicles.

5. B, the last
description would describe passive diffusion, as people representing as molecules are compacted and highly concentrated and as a result are constantly moving and staying still, moving from one area of the cell to another area, to ultimately be evenly spread out, and for the cell to acquire the material needed for its metabolism etc.
