One of the main ones are whether they are vertebrates orinvertebrates. vertebrates have a spinal column, invertebrates do not. 95% of all animal species do not.
I'm not sure what the second one would be.
the second one is whether they nurse their young
chordata and mammalia are the two great dividers
Fertilizers and Insecticides.
they use what their cells are made up of. they used to do how they look for example if the beaver and the chipmunk looked alike they would say that they are in the same group.
Biologists classify animals by their body structure, the way their body structure develops, and by their DNA.
Biologists often look for traits such as high yield potential and resistance to pests or diseases in crops. These characteristics help ensure that crops can produce abundant harvests while being able to withstand challenges in their environment.
All animals have unique characteristics.
No one name, as that is a VERY broad term. It would include ranchers, farmers, veterinarians, zookeepers, biologists, exterminators, cowboys and fishermen.
Not all animals look the same because they have evolved different physical characteristics to adapt to their environments and fulfill specific roles in their ecosystems. This diversity in appearance helps them survive and thrive in their habitats.
Some animals that are considered axolotl look-alikes include mudpuppies, newts, and salamanders. These amphibians share similar physical characteristics such as external gills and a similar body shape.
Many animals can camouflage themselves into their surroundings. This is why you should be familiar with how animals look and behave so you will always be able to spot them.
Molecular biologists, microbiologists, geneticists, immunohistologists, pathologists, neuroscientists, etc..
Yes, usually you can observe all of the charateristics of an animal with the naked eye.Yes, all characteristics that animals share can be observed with the naked eye.
Personally, from experience, dogs. But I bet that is not what you want. It sorta depends on opinion. And well, you can look up certain animals, and see their characteristics.
