The OP forgot to add: “Need answer fast!”
You never need an answer fast when you have a time machine.
Them’s the rules.
You’d think so, but apparently not. (see #5)

It’s not internally (ha!) consistent. However, as far as they’ve told us, yes. You should be able to send back anything as long as it’s covered in a live thing.
Why the T-1000 arrived naked, however, I have no idea.
So the ladies could take a gander at some sweet, sweet, Schwarzenegger beefcake.
Is it just me, or are we starting to get more and more bizarre and pointless OPs? I am starting to think we have some posters who are just bots stringing together random questions. On that note: If the moon was made of Roquefort cheese, could it be destroyed with a nuclear bomb? How many megatons would it take? I just gotta know.
No, no, Arnold was an exoskeleton with a skin covering. He would have been naked. Whatshisface the T-1000 is liquid metal. His clothes are him.
In one of the Terminator comics from Dark Horse, a Terminator is sent back in time with a couple of humans. After they all arrive, the Terminator tears the humans apart to extract futuristic weapons.
In the first Terminator comic (before Dark Horse bought the rights) a group of Terminators sew a pistol into a live human’s stomach so they can bring a weapon back with them.
In one scene in Robocop Vs Terminator, Robo simply uses a huge pile of vat grown meat and skin to cover a large weapon he wants to send back.

Outside a dog, a gun is a man’s best friend.
Inside a dog, it’s too dark to shoot.
