1. Which of the following are scientific hypotheses? (a) Chlorophyll makes grass green. (b) Earth rotates about its axis because living things need an alternation of light and darkness. (c) Tides are caused by the moon. 2. Well from science I know Tides are caused by the moon. Whether chlorophyll makes grass green, on the other hand I don't have a clue I have the internet but in a list of so many things I don't know what to choose. 3. With an under educated guess I would say the correct answer would be B Earth rotates about its axis because living things need an alternation of light and darkness. Yet I am conflicted in this answer because we know scientifically that every planet rotates with living organisms or not well at least every planet in this solar system. So in my mind all of these can be hypotheses.
