In a word, no, but scientists can make educated guesses. The closest living relatives of the dinosaurs are crocodilians and birds, and we can look to the ways they vocalize to give us a hint.
Alligators and crocodiles use their larynxes to communicate—they’ll hiss, groan, and yes, roar (here’s a compilation of their sounds). Dinosaurs might have had larynxes, but since those don’t fossilize, it’s impossible to know for sure. Birds, meanwhile, use an organ called a syrinx, which seems to have evolved after dinosaurs. That might indicate that dinos couldn’t vocalize at all, which would be a bummer.
However, there’s also a possibility that they evolved a unique way to vocalize. For example, based on studying their skulls and inner ears, some have theorized that hadrosaurs used their crests to bellow at each other.
So, they probably didn’t roar, but bellowing can be pretty cool too, right?
No. Turtle are from a branch of reptiles completely separate from dinosaurs.
A paleontologist (pay-lee-un-TAH-lah-jist) studies the fossils of dinosaurs.
No, not all dinosaurs were carnivores. There were herbivorous dinosaurs that primarily ate plants, such as the Triceratops and the Apatosaurus. Additionally, some dinosaurs were omnivores, meaning they ate both plants and meat.
Considering that most eukaryotic cells have mitochondria and that dinosaurs are eukaryotes like all other animals that ever lived, it is certain that they did have mitochondria in their cells. In fact, birds are considered dinosaurs (they certainly descended from dinosaurs) and their cells have mitochondria, so we can be as sure as scientifically possible that dinosaurs indeed did have mitochondria.
The two major groups of dinosaurs are the Saurischia (lizard-hipped dinosaurs) and the Ornithischia (bird-hipped dinosaurs). These groups are distinguished by differences in their pelvic bone structure.
Like lizards, crocodiles, and other reptiles, Spinosaurus didn't have external ears. However, they did have internal ears that detected sounds, and, like other dinosaurs, were definitely not deaf.
HA! there are no genetic mutations! DINOSAURS ARE DINOSAURS! DINOSAURS ARE DINOSAURS! no mutants

Platypuses are not dinosaurs; nor are they related to dinosaurs.
Sharks are Sharks and dinosaurs are dinosaurs. But there were animals recognizable as Sharks living when the dinosaurs did.
Young dinosaurs would have been called hatchlings. If you are asking what evolved from dinosaurs, the only descendants of dinosaurs are the birds.
Most dinosaurs were herbivores. There was a wide variety or carnivorous dinosaurs, though, and all herbivorous dinosaurs evolved from the earliest carnivorous dinosaurs. Birds are descendants of carnivorous dinosaurs.
Dinosaurs never flew dinosaurs were land reptiles although some dinosaurs could swim

No. Dinosaurs evolved from reptiles. Birds evolved from dinosaurs.
