Explain what is meant by the statement, “without the water cycle we could eventually run out of water on earth.”
thxs ppl

All living organisms require water and the water cycle describes the process of how water moves through the planet. Plants wouldn't grow without precipitation (and thus anything consuming the plants wouldn't survive and so forth). The water cycle brings water to everywhere on land, and is the reason that we have rain, snow, streams, and all other kinds of precipitation. Stopping it would cause an endless drought. No water flow in lakes would cause overgrowth, killing many species of fish and other lake wildlife.

yes, post it and i can try to you out.

i believe the answer is: b. mr. head had a long, tube-like face with a rounded open jaw and a short depressed nose.

this is because in the un-revised sentence it said that mr. heads face was long and tube-like, and he had a rounded open jaw. this is not a very grammatically correct because of how it seems to drag on with the and, replaced with, with, makes it sound more fluent in the description.
