Animal phyla are defined by vertebrae — which refers to what body part?

Question

Here is the question : ANIMAL PHYLA ARE DEFINED BY VERTEBRAE — WHICH REFERS TO WHAT BODY PART?

Option

Here is the option for the question :

  • Brain
  • Spine
  • Heart
  • Eyes

The Answer:

And, the answer for the the question is :

Spine

Explanation:

Animals are classified into the vertebrate and invertebrate groups by the taxonomical system. Members of the phylum Chordata, which includes humans and other animals with vertebrae, have spinal columns. Insects make up the vast majority of the world’s animal species, and this is despite the fact that all mammals and many other types of animals have spines.

Animal phyla are defined by vertebrae — which refers to what body part?
Animal phyla are a classification system used to group animals based on their physical characteristics, evolutionary history, and genetic traits. One of the primary ways that animal phyla are defined is by the presence or absence of vertebrae. Vertebrae are bones that make up the spinal column, or backbone, of animals. The spine is a critical part of the anatomy of animals with a backbone, providing support and protection for the nervous system.

Animals with vertebrae belong to the subphylum Vertebrata, which includes fish, amphibians, reptiles, birds, and mammals. Vertebrates are characterized by the presence of a spinal column, which is composed of individual vertebrae that are connected by ligaments and muscles. The spinal column serves several essential functions, including providing support for the body, protecting the spinal cord, and allowing for movement and flexibility.

In contrast, animals without vertebrae belong to the subphylum Invertebrata, which includes a vast array of animals, such as insects, crustaceans, mollusks, and worms. Invertebrates lack a spinal column and instead have a variety of other structural adaptations that provide support and protection for their bodies.

The presence or absence of vertebrae is just one of the many ways that animal phyla are classified. Animals are also grouped by their body symmetry, the presence or absence of a coelom (a fluid-filled body cavity), and the type of digestive system they possess.

Understanding the classification of animal phyla is essential for scientists studying animal biology and evolution. By grouping animals based on their physical characteristics, researchers can better understand the relationships between different species and how they evolved over time. This information can be used to develop new treatments and therapies for human diseases, as many animal species share similar biological processes and genetic traits with humans.
