Answer 1

The answer your looking for is bacteria

Answer 2

The answer to this is A, bacteria.

Bateria are unicellular, which means they're single celled orangisms. They do not have a nucleus, though their genetic materials are in a circular DNA strand and are not bounded by a nuclear membrane.
In addition, the bacteria can also be classified as a bacillus, which means the bacteria is in a rod shape.
