What else can I help you with?
Is this true to be classified as a animal you have to have a backbone?
No, not all animals have backbones. Animals are classified into two main categories: invertebrates (animals without backbones) and vertebrates (animals with backbones). Invertebrates make up the majority of animal species on Earth and include insects, mollusks, and jellyfish, among others.
The feeding relationships among plants and animals and among various animals in a biotic community is called a 1. trophic 2. biomass 3. symbiosis 4. niche 5. food web?
food web
Scientists view of animal relationships has changes since the mid-1900s. What development led to this change in scientist understanding of the relationships between animals?
Since the mid-1900s, the development of molecular biology, particularly the use of DNA sequencing, has significantly transformed scientists' understanding of animal relationships. This advancement allowed researchers to analyze genetic similarities and differences among species, leading to more accurate phylogenetic trees that reflect evolutionary relationships. Consequently, traditional classifications based on morphology alone have been re-evaluated, resulting in a more nuanced view of the evolutionary connections among animals.
Does a dichotomous key show evolutionary relationships among organisms?
yes
A sentence for food web?
The Food Wed has lot's of animals on it, and it's just like the water cycle but except with animals.

The study of embryological similarities and differences among species is called?
The study of embryological similarities and differences among species is called embryology. It involves comparing the development of embryos to understand evolutionary relationships and patterns in species.
How do similarities in developing embryos provide evidence of evolution?
Similarities in developing embryos provide evidence of evolution because they suggest a common ancestry among different species. These similarities in the early stages of development can indicate shared genetic and evolutionary relationships, supporting the idea of evolution through common descent.
How are embryos used as evidence of evolution?
Embryos provide evidence for evolution through comparative embryology, showing similarities in development among different species. This suggests a common ancestry and the existence of shared genetic information inherited from a common ancestor. By studying how embryos of different species develop, scientists can trace evolutionary relationships and infer evolutionary history.

food web
How can embroyotic development be used as evidence for evolution?
Embryonic development can show similarities among different species, which suggest a shared ancestry and evolution from a common ancestor. The presence of vestigial structures in embryos, such as gill slits in human embryos, can also provide evidence of evolutionary history. Additionally, comparisons of the timing and sequence of embryonic development in different species can provide insights into their evolutionary relationships.
How do developmental patterns help biologists determine evolutionary relationships among animals?
You know that Mrs. Lilliendahl doesn't approve of wikianswers... tisk tisk...
Why did DNA technology lead to more use to more use of cladistics?
It showed that different-looking animals are actually related. It showed new evolutionary relationships between animals. it changed ideas about which animals were closely related
Are ants and ladybugs invertebrates?
Yes, ants and ladybugs are invertebrates.Specifically, invertebrates have no backbones whereas vertebrates do. Vertebrates include amphibians, birds, fish, mammals and reptiles. Ants and ladybugs number among insects, which have no backbones and therefore are invertebrates.
Why humans are classified among the animals?
Are we not Animals?
What is the animals life among the Aztec?
They have animals
What is a field that focuses on people and the relationships among them?
sociology
