in heat transfer, as the fluid flows along the tube, the wall layers are heated or cooled. temp. variation occurs in the wall layers.

good luck :)

it should be all of them because it asks if you included all of those in your answer

explanation:

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
