Yes. 'Its' in that sentence is short for 'it is' so it should have an apostrophe.
The apostrophe should go before the "s" in "Drs" to show that it is a contraction for "doctor's." The correct sentence is: "That was the Dr.'s order."
The correct sentence would be:This is Luke's book.If Luke ended in an s, the apostrophe would be after the s ; since it doesn't, an apostrophe and then an s must be added for possession.Example: Jesus' disciples, John's disciples....
There is no apostrophe in that sentence. It would be in: The scouts' tents.

There are three types of apostrophe. The possessive apostrophe, to show that a letter is missing and to highlight a word or phrase, eg 'hasn't', doesn't', 'can't'. The possessive apostrophe would be used in a sentence such as 'The student's work was of a high standard' meaning the work of the student. However if you are using the word students in the plural form, it would be written 'students' work'.
You don't need an apostrophe in that sentence. Studentsis a plural word, not a possessive.
The apostrophe in "cyclist" would be placed before the last letter when indicating possession: cyclist's.
The apostrophe is not needed because deer is a singular and plural word. The sentence should read 'These deer antlers all have eight points.'
Bushfires shouldn't have an apostrophe.
The correct possessive form of "womens" is "women's," with an apostrophe before the s.
