Vitamins are organic substances because you get your vitamin D from the sun and the sun is not artificial is it. So that is false
Info:
Well, I do not know where you got that information from, but, it is true. Physics is a branch of science that studies something that is quite far from biology. Chemistry though, shares a lot of common studies though, and many times they depend on each other.

Comparison:
Physics: studies the behaviour of the universe, to keep it simple.
Chemistry: it's the study of matter and their properties/interactions.
Biology: studies life.
As you can see, the studies of physics cannot be used frequently while studying biology. But, the study of matter can really be helpful to the study of life because they're really related.

Amino acids contain nitrogen, in which helps make proteins in your muscles, skin and hair, otherwise if we had none, we would probably just wither away
Answer:
A hypothesis is an educated guess about something in the world around you. It should be testable, either by experiment or observation.
For example: A new medicine you think might work.
Explanation:
The answer is the butter contains a new arrangement of atoms.
When melting, the atoms breaks bonds between them, they spread further apart and therefore became liquid.
For A, butter does not change into another substance, nothing is added or combined.
For C, butter can turn into a solid again if we cool it down below it's melting point.
For D, butter still contains the same number of atoms, again, only they became further apart.
Therefore the answer is B.
