Question 17 braiding and cutting hair are both examples of physical changes. true false 2 points question 18 if you were to take several random samples from a mixture of salt and sand, the samples would: be identical no matter where in the mixture they were taken from be identical as long as the samples were taken at the same time be identical as long as the samples were the same size not be identical

Question 17:

False; cutting hair would change what it looks like but, braiding it keeps it the same substance it is.

Question 18 :

My best guess would either be A or D. I would lean more towards D because if there are different mixtures then it depends on what you are mixing.

Hope it helps in some way. <3
