ANSWER: Your answers are correct with these exceptions Destiny

#5 is a bad question.  The first law tells neither mayyer nor energy can be destroyed. This is because they are the same thing

# 9 B is correct

#12 D is correct

#13 D is correct

#14  C is correct

#16 Information is missing here

$ 18 D is correct

Destiny Hmm! You are not Miley Cyrus are you?

QUESTION: My name is Destiny, but she must be doing home schooling too, taking the same exam as me. Is all the other questions you didn't mention wrong?

ANSWER: The questions I did not mention are correct.  The ones I listed are ones I corrected.  I answered # 14 wrong.  A neurons is the right answer

I was kidding about Miley Cyrus.  She is probably the most famous young performer today (Hannah Montana)  Her real name is Destiny Hope.

---------- FOLLOW-UP ----------

QUESTION:
Really! I thought Hannah Montana was her birth name; more-or-less the name Hannah Montana fits her so will. The man that plays Destiny Hope father on The Hannah Montana Show is really her father...Right? I don't watch TV as much as I should. O'yeah, I really want to thank you for checking my work over for me.

I found it," Destiny Hope Miley Cyrus". Thank you!

Answer
Her Father is country star Billy Ray Cyrus who also plays her father on TV.  They called her smiley as a baby and she called herself Miley.  Her success is ,in my opinion, the result of Disney merchandizing because althrough she is cute and a good young actress I don't think she can sing.
