What kind of symmetry do arthropoda crustacea have?
Phylum arthropoda is classified under a taxonomical unit (subregnum) Bilateria, which includes all phyla except the placozoans, cnidarians, ctenophores and sponges (porifera). Bilateria all have bilateral symmetry, or could be reflected in a hypothetical mirror placed down the midline, and includes the crustaceans.
Why make sure you protect species of porifera in the ocean and ensure they do not go extinict?
Every species in this planet has a significant role to play in the environmental balance, hence it is impoortant to preserve them all. Porifera is a species in ocean that supports many other organisms to flourish. in fact there are living organisms that cannot live without them. For example, a kind of sea grass grows on the bed made of these sponges so that it is placed higher and gets enough sunlight. In return , the seagrass meadow does not allow starfished to feed on the sponges. And there are many species of shrimps whoes home are these sponges.
What phylum are animals placed in that have a notochord?
Chordata
What is another term for the classification categories into which organisms are placed?
The term, phylum, is a term used for classification categories into which organisms are placed. A phylum is a subcategory of a species.
Phylum that also called a conjugation fungi?
Conjugation fungi are placed in the phylum Zygomycota. They are characterized by their unique method of sexual reproduction called conjugation. Members of this phylum include bread molds such as Rhizopus.
Why are sponges placed in a taxonomic group beside the other animals and considered an evolutionary dead-end by many zoologists?
Sponges are placed in a separate taxonomic group, the Porifera, because they possess a simple cellular organization and lack true tissues and organs, distinguishing them from more complex animals. Their unique feeding and reproductive mechanisms, along with their asymmetrical body structures, indicate an ancient lineage that has not significantly evolved over time. Many zoologists consider them an evolutionary dead-end because they do not exhibit the advanced characteristics seen in other animal groups, limiting their evolutionary adaptability and diversification.
What is the classifacation for a spider?
The classification of a spider is Arachnida And is placed in Phylum Arthroda And order is Araneae
Nickname given to King Louis Phillippe?
the "Citizen King" - called this because he was a "bourgeois" king This question is more appropriately placed in the 19th century context rather than the French Revolution the "Citizen King" - called this because he was a "bourgeois" king This question is more appropriately placed in the 19th century context rather than the French Revolution
How do sponges die?
Sponges can die if they are exposed to air, starved, improperly placed, or experience algae overgrowth. The will also die, or course, if they are eaten by a predator.
What is a sac fungi?
Mushrooms were originally classifed in the phylum Basidiomycota, and the sac fungi were originally placed in the phylum Ascomycota. Recently, these two phyla have been merged to form the Dikaryomycota.
What food group is peppermint in?
Peppermint is not truly located in any food group. It would most appropriately be placed in the junk food (use sparingly) category.
Why were living sponges placed in Ca2 plus Mg2 plus free seawater overnight?
Living sponges are often placed in a solution of Ca²⁺ and Mg²⁺ in free seawater to study their physiological responses and to maintain their osmotic balance. Calcium and magnesium ions are essential for various cellular processes, including maintaining cell structure and function, as well as facilitating certain biochemical reactions. The overnight immersion helps ensure that the sponges remain healthy, hydrated, and able to perform their natural filtering and feeding functions in a controlled environment. This setup is commonly used in research to investigate sponge biology and ecology.
