Answer:
an independent variable is a variable that changes an a dependent variable is something that doesn't change
Explanation:
like if i put two fish is different size tanks and measured them after so long
measuring them would be dependent and putting them in different size tanks would be independent
Density - Calculated from measurements of mass and volume
Atom - the basic particle of matter
Motion - calculated from measurements of distance and time
Energy - can change form and move matter
Can't see the last one but you know process of elimination soo
Answer:
carbohydrates, proteins, fats, vitamins, and minerals
Explanation:
<span> For a start, when you have a question that needs answering in science, you formulate a null hypothesis. That is a negative statement which you then set out to prove or disprove. This is just a convention. So if your initial question is for example, "Does sugar dissolve in water?"
Your null hypothesis will be "Sugar does not dissolve in water."
You then set up your experiment and get some data.
Now if your data doesn't support your null hypothesis then you reject it and make the statement ,"Sugar does dissolve in water." As you can see from this simple example, a non-result is still a result so the idea of formulating new tests as mentioned by another answerer isn't necessary and in some ways is the incorrect thing to do. In science, hypotheses are often not supported by data and i would argue that this is the case a lot of the time. A non-result is still a result and you will have plenty to write about whichever way it goes. </span>
