What is the significance of coelom in the classification of animals?
Body cavity or coelom is generally the third most important criteria, after levels of organisation and body symmetry, in the classification of animals. Animals can be classified into four types on the basis of the type of body cavity they possess:Acoelomate (coelom absent): includes animals like sponges, coelenterates and flatworms,Pseudocoelomate (false coelom present): includes roundworms, andEucoelomate (true coelom present): includes all chordates, besides rest of the invertibrates.
Which phylum has a pseudocoelom?
The phylum Nematoda has a pseudocoelom. This type of body cavity is not completely lined by mesoderm tissue, giving it certain characteristics of a true coelom but lacking some key features.
What is the scientific name for sea stars?
asterios forbesii Well yes but it has more than that
What data type stores Web addresses in access?
The data type that stores web addresses (URLs) in Access is typically a "Hyperlink" data type. This data type allows users to store and access web addresses as clickable links within the database.
What are the objectives of selecting a data type for a field?
The objectives of selecting a data type for a field include ensuring data integrity by restricting the type of values that can be stored, optimizing storage space by choosing the most appropriate data type for the data being stored, and facilitating efficient data retrieval and manipulation by selecting a data type that best fits the operations that will be performed on the data.
What is the difference from a starfish and a brittle star?
a brittle star is a type of starfish.
What type of symmetry does a brittle star have?
They are very brittle and they can get up to a very bright temperature
What type of coelom does a hydra have?
Hydras are acoelomates.
Does a grasshopper have a coelom?
Yes, grasshoppers do have a coelom. This is the type of body cavity they have. There are over 10,000 known species of grasshoppers.
What type of coelom does an enterocoelous animal have?
A coelomate animal is the one which has a body cavity in which well developed organs can be accomodated.
What type of echinoderm has flexible arms that are easily broken to escape predators?
The brittle star has very flexible arms that can brake of in situations involving a predator. The broken arms will continue to wiggle and move to distract said preditor, allowing the brittle star itself to escape.
What type of coelom does ascaris have?
Ascaris has a pseudocoelom, which is a body cavity that is partially lined by mesoderm but lacks a full peritoneal lining like a true coelom.
The body cavity is a true coelom why?
A true coelom is a body cavity completely lined with mesoderm tissue. It provides space for organ development, protection, and flexibility. This type of coelom allows for efficient organ function and movement within the body.
Is splanchnocoel a true coelom?
The splanchnocoel is not a true coelom; rather, it is a type of body cavity found in certain organisms, particularly in some invertebrates like arthropods. It is derived from the embryonic mesoderm but is not entirely lined with mesodermal tissue, which is a defining characteristic of a true coelom. In contrast, a true coelom is a fully enclosed body cavity that is completely lined by mesoderm. Therefore, while the splanchnocoel serves as a body cavity, it does not meet the criteria to be classified as a true coelom.
Does brittle mean clever?
Brittle can mean:breakable, easily brokena type of candycold or unfeeling
Is the type of body cavity shared by all mollusks is a pseudocelom?
The type of body cavity shared by all mollusks is pseudocoelom is a false statement. The correct answer is coelom.
An ocean animal with five eyes one on each arm and has hundraads of tube feet?
This description matches the deep-sea creature known as a brittle star, which is a type of echinoderm. Brittle stars have a flexible disc-shaped body with five arms, each of which contains an eye at its tip. They also have hundreds of tube feet that they use for movement and sensing their environment.
