Answer:
guanine, cytosine, cytosine,adenine,thymine,guanine
Explanation:
This is because during DNA replication the complementary base pairings are Adenine and Guanine, Thymine and Cytosine.
Correct matching of invertebrates and its characteristics are as follows:
Sponges are animals which have many cell but no mouth, muscles , heart or brain. They are sessile and can not move from place to place like other animals do, filter feeding animals with an asymmetrical body plan.
Cnidarians are the animals with radial symmetry and stinging cnidocyte cells. These animals consists a special cell cnida which functions in preying catch and defense. example- jellyfish, anemone.
Flatworms are the worm like animal which do not consist a body cavity or coelom. example- fluke and tapeworms.
Roundworms or threadworms are segmented worms that can live in water or land. They consist a body cavity and internal organs. examples- pinworms and hookworms.
Mollusks are the animals which consist mentle, foot and and sometimes a shell. example- octopus, squids.
Echinoderms are the animals which have radial symmetry and an endoskeleton made out of calcareous plate. These animals live only in marine environment.These animals lack circulatory and excretory systems.
Arthopods are the animals with jointed legs and an exoskeleton made out of chitin. example- spiders, shrimps and crabs.

Answer:
If we're talking about human organism then
It is multicelular.
It has a backbone.
It contains cells without nuclei.
Explanation:
human as almost all animals in the world is multicellular meaning they have more than one cell (some bacterias has only one)
backbone or "vertebra" is the is the bone of our back who supports us making us stand up.
Yes our cells contain nuclei
, The nucleus contains nucleoplasm, a component where it is immersed in genetic material and as structures that are important for the performance of its functions
And finally our body don't have radial symmetry, radial symmetry is when you can "cut" the image in more than one piece keeping the symmetry in every side, some animals with radial symmetry are the starfish and the jellyfish.
Answer:
Complex brain.
Explanation:
The cranial capacity of Homo sapiens are responsible for their successful adaptation on earth. They have the cranial capacity of around 1400cc.
The major environmental conditions has changed but the complex human brain has helped him to sustain and understanding the nature. Humans are successful to sustain on this earth due to their complex brain.
