Only in the most general sense, in that both giraffes and whales are mammals.
Whales live in the ocean, giraffes lives on the Savannah, and aren't known to go wading on the beach. So no, whales don't eat giraffes, as they never meet.
The only mammals that do not have live birth are monotremes. Giraffes and whales are mammals, but not monotremes. So yes.
No, giraffes and zebras are not related.
Yes!
No they aren't. Blue whales are.
Dolphins and cows are both mammals, but they are not closely related. Dolphins belong to the order Cetacea along with whales and porpoises, while cows belong to the order Artiodactyla, which includes pigs, giraffes, and deer.
Giraffes are the tallest animals, so no animals are taller. Some whales are longer, so there are bigger animals.
