What Is The Correlation Between Mirna Diversity And Animal Complexity?

What can we infer about the function of miRNA variety in the development of animal complexity based on the fact that there is a positive connection between animal complexity and the number of different miRNAs? It seems to imply that discrepancies in the developmental control of gene expression are to blame for the variances in the complexity of different animal species.

What is the key difference between a Coelom and a Pseudocoelom?

  1. What is the most significant distinction that can be made between a coelom and a pseudocoelom?
  2. A real bodily cavity is referred to as a coelom, whereas a false coelom that is only partially functioning is referred to as a pseudocoelom.
  3. Only a coelom has mesoderm tissue completely lining its inside.
  4. Pseudocoeloms were present at an early stage in the evolution of animals and eventually developed into coeloms.

What animal phylum gave rise to the animal kingdom?

Porifera is the animal phylum that is most similar to the protists that were responsible for the origin of the animal world. (There is no real tissue in sponges, which is one piece of evidence that supports this theory. Another piece of evidence is the close resemblance between choanocytes and choanoflagellates.)

Which of the following statements applies to both nematodes and arthropods?

Nematodes and arthropods both have segmented body designs due to their shared ancestry. Nematodes and arthropods alike must undergo the process of molting in order to progress in size. – The length of the cuticle of nematodes increases as the animal develops.

How does a pseudocoelomate animal differ from a acoelomate animal?

Acoelomates are creatures that do not have a bodily cavity within their bodies. The phylum Platyhelminthes is comprised of organisms that are considered to be acoelomates since they lack body cavities. Animals that are classified as pseudocoelomates are those in which the body cavity does not grow from the mesoderm but rather from the blastocoel (cavity present within the embryo).

What is the difference between an animal that is a Coelomate and one that is a pseudocoelomate?

The creatures known as coelomates and pseudocoelomates are both triploblastic and have fully developed digestive systems. Coelomates are characterized by the presence of a body cavity known as the coelom inside the mesoderm. There is a hollow in the body of pseudocoelomates known as the pseudocoelom, which is located between the endoderm and the mesoderm.

What is the relationship between choanoflagellates and animals?

Choanoflagellates are among the most closely related single-celled organisms to metazoans that are still alive today. Because of this link, choanoflagellates are to metazoans (which include all animals, from sponges to flatworms to chordates) what chimps are to humans.

How did the animal kingdom evolve?

According to the findings of genetic research, the evolution of multicellular organisms probably occurred around one billion years ago; this theory is confirmed by fossil embryos found in rocks in China that date back approximately 600 million years.

Why do scientists believe animals arose from protists?

Animal Origins Researchers believe that cells in some protist colonies become specialized through time to perform a variety of tasks. After some time, the specialized cells began to rely on one another for their continued existence. This led to the evolution of the first multicellular animal.

What are the advantages of the arthropod’s body structure compared to the structure of the less complex animals?

Arthropods were able to have a far larger degree of flexibility and range of movement because to their jointed appendages. Protection, water retention, structural support (especially on land), and counterforce for attachment and contraction of muscles are some of the benefits of having a hard outer layer. Other advantages include a longer lifespan.

What do arthropods and nematodes have in common?

Ecdysozoa is the name of the group of organisms that have a common ancestor, which includes both nematodes and arthropods. The word ″ecdysis,″ which refers to the process of shedding or molting the exoskeleton at regular intervals, is where the term ″ecdysis″ originates from.

What is a common feature shared by both roundworms and arthropods?

1. Which group of organisms, the arthropods or the roundworms, have certain characteristics in common? chitin.

What is the true advantage for a Coelomate organism compare to acoelomate organism?

Figure 01: Coelomates In addition to this, the coelomic fluid serves as a transport channel for a wide variety of soluble gases and metabolites. As a consequence of this, this is an advantage that is more significant for organisms that have complex body shapes and a low surface to volume ratio.

Which group of animals have pseudocoelomate is made up of?

Nematodes, rotifers, gastrotrichs, and introverts are all examples of the class of organisms known as pseudocoelomates. To use the correct terminology, certain members of other phyla are also considered to be pseudocoelomates.

What advantages does a coelom give to an animal?

  1. The following is a list of the benefits that the coelom offers: The organs, such as those in the digestive tract, require additional room so that they may continue to develop
  2. During the breeding season, certain organs, such the gonads, have a greater demand for space.
  3. Additionally, coelom enables the construction of a well-organized circulatory system, complete with a heart that is capable of efficiently drawing blood from arteries
