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
Vertebrates do not have exoskeletons. However, they do have internal organs, vertebral columns, and tails. Lampreys are vertebrates that also do not have jaws.
No, not all vertebrates stand up straight. Some vertebrates, like humans and birds, are capable of standing upright, but others, like most fish and reptiles, have different body shapes and movement patterns that do not involve standing upright.
No. The 1st vertebrates appeared in the fossil record about 525 million years ago during the Cambrian Period. This was in the Paleozoic Era.
humans are vertebrates as hey have the vertebral column(to be more specific the notochord). u can feel your vertebral column by placing your hand on your back.the bony structure that seems to divide your back into two equal halves is nothing but your vertebral column.
Some of the specific kinds of AIOs include the file system programming.
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.
Vertebrates do not have exoskeletons. However, they do have internal organs, vertebral columns, and tails. Lampreys are vertebrates that also do not have jaws.
no
90% of animals are invertebrates and only 10% are vertebrates they have backbones
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.
