Answer:

13. Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state.

14.Chromatography is a laboratory technique for the separation of a mixture.

15.The word "amphibian" comes from a Greek word that means "both lives." This is because frogs start their lives in the water and then live on land.

16.Most amphibians breathe through lungs and their skin. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist.
