Which of the following organisms are Deuterostomes?

The three major clades of deuterostomes are Chordata (e.g. vertebrates), Echinodermata (e.g. starfish), and Hemichordata (e.g. acorn worms). Together with Protostomia and their out-group Xenacoelomorpha, these compose the Bilateria, animals with bilateral symmetry and three germ layers.

Which organism would you classify as an animal?

Kingdom	Types of Organisms

What do all deuterostomes have in common?

The unique feature which all deuterostomes have in common is that the blastopore formed during gastrulation becomes the anus which would be consistent…

What do many organisms with deuterostome development have in common?

Most deuterostomes have indeterminate cleavage, meaning that each cell produced by early cleavage divisions retains the capacity to develop into a complete embryo.

What do all animals have in common?

All animals are eukaryotic, multicellular organisms, and almost all animals have specialized tissues. Most animals are motile, at least during certain life stages. Animals require a source of food to grow and develop. All animals are heterotrophic, ingesting living or dead organic matter.

What makes the animal kingdom diverse?

Barring a few exceptions, animals are multicellular eukaryotes that move, consume organic matter, and reproduce sexually. Although these attributes are shared, species within this kingdom are also extremely diverse. This diversity is due to adaptation of each species to a different niche.

Which of the following characteristics is common to all known animals?

Which characteristic are unique to animals?

Animals are multicellular eukaryotes that lack cell walls. All animals are heterotrophs. Animals have sensory organs, the ability to move, and internal digestion. They also have sexual reproduction.

Which of the following was probably an important factor in bringing about the Cambrian explosion?

Thus the correct answer is the origin of bilateral animals happened in the Cambrian explosion.

Which feature of Deuterostome development explains the formation of identical human twins?

Which feature of deuterostome development explains the formation of identical human twins? Which feature of deuterostome development explains the formation of identical human twins? A. Deuterostomes have radial cleavage.

What are three developmental traits that all deuterostomes have in common?

The chordates are a phylum of animals within the deuterostomes, which have the following common similarities:

A notochord. …
A hollow dorsal nerve chord—This is formed from the ectoderm and runs the length of the body. …
A post-anal tail. …
Pharyngeal gill slits in at least some point of their development.

What traits are common in the two groups of animals?

What features are common to both animal groups?

All animals are eukaryotic, multicellular organisms, and almost all animals have a complex tissue structure with differentiated and specialized tissues. Most animals are motile, at least during certain life stages.

What do all Animalia have in common?

Animaliaanimals All members of Animalia are multicellular, and all are heterotrophs (that is, they rely directly or indirectly on other organisms for their nourishment). Most ingest food and digest it in an internal cavity. Animal cells lack the rigid cell walls that characterize plant cells.

What are 4 Traits shared by all animals?

The set of characteristics provided by Audesirk and Audesirk are:

Animals are multicellular.
Animals are heterotrophic, obtaining their energy by consuming energy-releasing food substances.
Animals typically reproduce sexually.
Animals are made up of cells that do not have cell walls.

What are some characteristics that all animals share?

Summary

Animals are multicellular eukaryotes that lack cell walls.
All animals are heterotrophs.
Animals have sensory organs, the ability to move, and internal digestion. They also have sexual reproduction.

Which of the following statements best represents evidence supporting the leading hypothesis regarding the evolution of jaws in vertebrates?

Which of the following statements best represents evidence supporting the leading hypothesis regarding the evolution of jaws in vertebrates? Both jaws and gill supports are derived from the same type of specialized embryonic cells.

How is the Cambrian explosion related to changes in the atmosphere?

A team of researchers from the University of Oxford, University of Leeds and UCL have found that extreme fluctuations in atmospheric oxygen levels corresponded with evolutionary surges and extinctions in animal biodiversity during the Cambrian explosion.

What happened during evolution that led to the appearance of jaws and skulls in chordates?

–Evolution of neural crests forming between the neural tube and ectoderm. These cells give rise to some structures unique to vertebrate skull and jaw. -The pharyngeal gill slits become gill slits associated with breathing.

Which evidence supports the hypothesis that four limbed animals came from fish Select all that apply?

Which evidence supports the hypothesis that four-limbed animals came from fish? –DNA analysis shows that fish are tetrapods' closest relatives. -The fossil record shows more and more tetrapod-like fish before the appearance of tetrapods about 365 million years ago. -Both fish and four-limbed animals are vertebrates.

What occurred during the Cambrian explosion How is this significant in terms of common ancestry?

The Cambrian period, part of the Paleozoic era, produced the most intense burst of evolution ever known. The Cambrian Explosion saw an incredible diversity of life emerge, including many major animal groups alive today. Among them were the chordates, to which vertebrates (animals with backbones) such as humans belong.

How does the geologists hypothesis explain the Cambrian explosion that gave rise to the diversity of species?

They called this the Cambrian Explosion. Today, scientists have several theories to explain the phenomenon. One theory is that life may have been able to evolve quickly because the Earth had changed so much that it created enough new niches that species could rapidly fill them.
