Water flows of the plants stem in force of gravity in which of the following ways could the movement of water up a plant be modeled? a. blow air through a clear straw in glass of water. observe the level of water inside the staw. b. place a clear pipe in a small tub of water. shake the tub back and forth. watch how water moves around pipe. c place the tip of a sponge in water dyed with food coloring. watch how the water moves up the sponge. d pour a glass of water of top of a towel thats is spread out on a table.

C because the sponge will take up the water through absorption which is how plants pull water up

The correct answer will be option-C.

Explanation:

The water moves from the ground to the top of the plants against the force of gravity in xylem tracheids and vessels. The physical force that acts on the upward movement of water is the "capillary action".  

In the given questions the demonstration of the upward movement of the water can be demonstrated by the placing a sponge in colored water as. When the sponge will be placed in colored water the water will move upward through capillary action which will be easily observed as the water is colored.

Thus, option- C is the correct answer.

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.
