Answer:
you can change the ice back into water
Explanation:
physical change is when you can revert what has happened, chemical change is eternal.
Organisms (belonging to the same species) may adapt in different ways to better exploit different environments or resources-- survival of the fittest. They also may evolve varied characteristics for attracting mates for reproduction. This means that different groups evolve differently. Over time, these groups or populations may become so different that they can no longer breed together -- and separate species are formed.
If a juice drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of drink on an average and any overfilling or underfilling results in the shutdown and readjustment of the machine, in order determine whether or not the machine is properly adjusted, the correct set of hypotheses is H0: µ=12 and Ha: µ≠12. (Option C).
In scientific context, a hypothesis or hypotheses refers is a testable statement defining the relationship between variables or a proposed justification for an observed phenomenon. In this case, since the drink filling machine that is perfectly adjusted fills 12 ounces of drink on an average, after readjustment to determine if the machine is properly adjusted, the hypotheses that must be test that if the average of filling is equal to 12 ounces or not.
Note: The question is incomplete as options are missing. The options are a) H0: µ < 12 and Ha: µ≥12, b) H0: µ≤12 and Ha: µ>12, c) H0: µ=12 and Ha: µ≠12, d) H0: µ≠12 and Ha: µ =12.
