Animals – a separate Kingdom, eukaryote (has cell nucleus), and almost always – heterotrophs (feed on ready organic substances).
In contrast to the kingdoms of Plants, Fungi (eukaryotes) and Bacteria and Archaea (prokaryotes), animals have nervous and muscle tissue. It's only their feature.
Therefore it is not suitable answer 1 is photosynthesis ( Plants, some Bacteria and Animals are rarely as exception).
Not suitable: the answer is 3 (the metabolism is in all living things, except the Viruses when they are outside the cells) and response 4 (breathe by the representatives of all the kingdoms of the Empire Cellular, with the exception of certain anaerobic organisms).
The correct answer is 2.
The truth here is the Subkingdom Protozoa (Protozoa) quite badly with the nervous impulses, as this is a single-celled animals. But the drafters of the exam do not care.
We'll pass the biology exam for 100!
