Explanation:

First of all, if you pay attention to the details of the question it states that scientific hypothesis should be specific and demonstrate the relationship between the independent and dependant variable.

Answer A - Does demonstrate the relationship between the independent and dependant variable. but it's not very specific. Thus it is Not the answer.

Answer B - is not specific or demonstrates the relationship between the independent and dependant variable. Thus it is Not the right answer.

Answer C - Fits the criteria as it is specific, and demonstrates the relationship between the independent and dependant variable. Thus it is the Right answer

Therefore your only option is C. Your welcome, and have a wonderful day

All physical changes can be identified at the macroscopic level. true or false
Aliun [14]

Answer:

True

Explanation:

The physical changes are reversible in most cases and these changes are not the chemical changes which means that it is only the change in its state not in their nature. Just take the example of water, on cooling it becomes solid and change in color can be seen which is white in solid form and colorless in liquid form. This is also reversible and is a physical change. This means that physical changes can be identified at macroscopic level. Hence the answer is true.
