Yes, it is correct to say 'when you get back home, tell her to call me'. You insert a comma after the word 'home'.
Neither is correct, first because the understood subject of the verb is "you" and second "respond back" is wrong. Otherwise there is a convention about the order of pronouns and names, but it is not a grammatical rule.
The comma is relatively new to the punctuation family (couple hundred years old), so let's go back even farther than that. Jim has a farm and he wants to tell someone he owns this farm, so he's going to say "Jim's farm", right? Wrong. There was no such thing as ('s) to show possession. He would have to say "Jim his farm" to show possession. Fast-forward a couple hundred years and people start to say that doesn't make since, so they changed "Jim his farm" to "Jim's farm" replacing the (hi) in his with a comma. Thus the comma was created. The funny thing about this is that women did not own anything back in the days, so you would never say "Jenny her farm" and therefore ('r) was never created. Think about it further and when someone shows possession for a female (jenny's farm) they're actually saying (Jenny his farm) replacing the (hi) in his with a comma. If we wanted to be politically correct it should be: Jenny'r farm And Jim's farm

If a particle were sent back in time, it could potentially cause paradoxes and disrupt the natural flow of events. The consequences of time travel are not fully understood and could have unpredictable effects on the timeline.

the mechanism for continental drift was not well understood at the time, and there was no evidence to support the idea of continents moving. It wasn't until the theory of plate tectonics was developed that the idea of continental drift became widely accepted.
You could either wait until it grows there or get extensions
In modern writing style, it is common to use only one space after a comma when it is used as a punctuation mark. The double-spacing after a comma is a convention that dates back to the typewriter era, but it is no longer necessary with the use of modern word processing software and typesetting tools.
