What organisms have pharyngeal gill slits and a dorsal hollow nerve cord at some time in their development?
Organisms that have pharyngeal gill slits and a dorsal hollow nerve cord at some point in their development include chordates, such as fish, amphibians, reptiles, birds, and mammals. These features are key characteristics of chordates during their embryonic stages.
Why is the number of pharyngeal gill slits in sharks fewer than that of other marine fishes?
"Jaws are believed to have evolved from the first pair of gill arches of agnathans. The second pair of gill arches became support structures for the jaws." - Biology Laboratory Manual, Ninth Edition Darrel S. Vodopich and Randy MooreSo, sharks have fewer gill slits because the first two pairs became the jaw and the structural support for the jaw.
At some point in their lives all chordates have what characteristics?
All chordates have a notochord at some stage in their development, even if it is only at the embryonic stage. The notochord is a flexible structure located in front of the dorsal nerve, which all chordates also have.
Do frogs have Pharyngeal Pouches?
Yes, frogs have pharyngeal pouches, which are structures in their throat that aid in respiration. These pouches play a role in the exchange of gases during breathing.
The three things all chordates have?
Chordates all possess a notochord (dorsal supporting rod), gill slits, and a dorsal nerve cord some time in their life cycles.
What do Pharyngeal pouches become in Fish?
gill slits
What are the characteristics of nonvertebrate chordate?
Chordates are the organisms that have a rod like cartilagenous structure called notochord which gives rise to nervous system. These have pharyngeal gill slits. Nonchordates are the organisms that do not have a notochord. These do not have pharyngeal gill slits.
What are the respiratory organs of chordates?
Gills I think, like pharyngeal gill slits ... maybe ....
What organisms have pharyngeal gill slits and a dorsal hollow nerve cord at some time in their development?
Organisms that have pharyngeal gill slits and a dorsal hollow nerve cord at some point in their development include chordates, such as fish, amphibians, reptiles, birds, and mammals. These features are key characteristics of chordates during their embryonic stages.
What is the main characteristic of chordate?
They are: a. a dorsal, hollow nerve chord b. a notochord c. pharyngeal gill slits d. and a post-anal tail
What four characteristics set Chordates apart from other organisms?
for plato users the answer is B. notochrd, nerve cord, pharyngeal gill slits, postanal tail
Do sharks develope breathing organs from pharyngeal anrches?
Yes, sharks develop their breathing organs, specifically gills, from pharyngeal arches. During embryonic development, these arches form structures that eventually give rise to the gill filaments and other components of the respiratory system. This process is part of the broader evolutionary pattern seen in many vertebrates, where pharyngeal structures play a crucial role in respiratory development.
All vertebrate embryos develop gills during one of the many growth phases in their development?
It would be more appropriate to say that all vertebrate embryos develop pharyngeal gill slits during one of the many phases in their embryonic development. This is because while gills are specifically present in fishes, pharyngeal gill slits are a general chordate feature.

What is the correct spelling of the adjective for pharynx?
The correct spelling is "pharyngeal."
What organs do most fish breathe with?
Gills provide means of respiration for most fishes. Gills function very similar to that of our lungs. Pharyngeal gill slits usually help to filter out waste particles during breathing in of the water.
What chordate structure is paired?
The pharyngeal gill slits in chordates are typically paired structures, found on either side of the pharynx. These slits are important for respiration, filter feeding, and in some cases, evolved into other structures such as jaws in vertebrates.
