Vertebrates have an internal skeleton of cartilage or bone, with vertebrae surrounding the dorsal nerve cord.
A different Perspective:
There are overlaps, but generally:
Animal oxigenates using gills, or using lungs
Has hollow bones, or solid
Is ectothermic, or endothermic
Has fins, or no fins
Requires moist, water, or air environment
Lays eggs in water, or out of water
Lays eggs, or gives live births
Number of each type of vertebrae
No, infact some vertebrates cannot stand at all.
Vertebrates do not have exoskeletons. However, they do have internal organs, vertebral columns, and tails. Lampreys are vertebrates that also do not have jaws.
The kind and numbers of fossils found in different kinds of rocks give clues about past ecosystems. Fossils give evidence that, in any ecosystem, some plants and animals survive well, and some do not.
i wouldn't classify bugs as decomposers. Decomposers are monera and fungi. i would probably classify bugs as some sort of scavenger.
matter and animatter ! :) GET SOME.
The presece of a vertebrate.
because some vertebrates that have high offs doesnt drink many milk so her bones break when they have many babys.
Because some animals have features of different groups of vertebrate. For example the duck built platypus is classified as a mammal but has some bird (a beak) and it lays eggs which a mammal doesn't do.
some are, some aren't. Reptiles are vertebrates and cold-blooded.
Some of the reptiles that are vertebrates: -snake -lizard -tortoise -crocodile
Let's classify some of these samples.
According to science there is about 100 kinds of cancer but we only know 87 however the are some sickness that are being discovered that will classify as caner.
Some scientists classify seaweed as plants, and some classify seaweed as protists.
no
90% of animals are invertebrates and only 10% are vertebrates they have backbones
No, infact some vertebrates cannot stand at all.
Some good topics to classify could be foods or animals. Classifying people is a good idea too. Try to classify something that you are interested in, and try to think of something creative as well.
