What is the embryonic structure in chordates that is usually replaced?
In chordates, the embryonic structure that is usually replaced is the notochord. The notochord serves as a flexible rod that provides support during early development but is typically replaced by the more rigid vertebral column (spine) in vertebrates. While it is prominent in the embryonic stages, the notochord may persist in some organisms, such as in certain species of invertebrate chordates.
Why would you be unlikely to find a notochord in an adult chordate?
In adult chordates, the notochord is typically replaced by the vertebral column (spine) during development, providing a more rigid structure for support and movement. While some primitive chordates retain the notochord throughout their life, most vertebrates exhibit a transition to a bony or cartilaginous backbone, which serves similar functions but offers greater protection and strength. Consequently, the notochord is usually only present in the embryonic stages or in specific chordate groups that do not develop a backbone.
What are common carbon backbone structures?
The three kinds of carbon backbones are straight chain,branched chain,and the ring.
Explains what happens to the structure of ATP when energy is released?
The structure of ATP usually has an ordered carbon compound as a backbone, but the most critical part is the phosphorous part, the triphosphate.
What are the different subgroups of vertebrate animals?
A vertebrate is an animal with a backbone (spine) and an invertebrate has no backbone, usually it has an exoskeleton.
Is a pipe fish vertebrate?
wea vertebrate is an animal with a backbone (spine) and an invertebrate has no backbone, usually it has an exoskeleton.... you tell me...
Why do spiders not need a backbone?
Spiders do not have a backbone because they belong to a group of animals called arachnids, which have an exoskeleton instead of an internal skeleton. This exoskeleton provides support and protection for their bodies. Spiders are able to move and function effectively without a backbone due to this exoskeleton.
Why are animals without skeletons usually small and live in water?
There are various animals that are without a skeleton are usually small and live in water, like the squid. They are usually small and live in water because there is no backbone to support a large structure.
What are the phosphate ions in the DNA chemical backbone?
Usually made of sugar
What are backbones usually made out of?
the backbone is made of the spinal cord and nerves!
Do carbohydrates usually have a hydrocarbon chain?
Yes, carbohydrates are organic molecules made up of carbon, hydrogen, and oxygen atoms. They typically have a backbone of carbon atoms bonded to each other, forming a chain or ring structure.
What kind of atom forms the backbone of monomer and a polymer?
The Carbon atom usually forms the backbone of polymers and quite often oxygen can do also as in polyether polyols etc.
