Is an animal with a backbone and gills but no notochord still a chordate?
No, an animal with a backbone and gills but no notochord would not be considered a chordate. Chordates are defined by the presence of a notochord at some stage of their development, along with a dorsal nerve cord, pharyngeal slits, and a post-anal tail.
Can chordates not have a notochord and still be what they are?
The presence of a notochord at some point in the organism's development is one of the characteristics that distinguishes chordates from other phyla. Without it, I'm not sure if the organism would be considered a chordate.
What makes an invertebarte an invertebarte?
An animal that would be defined an invertebrate would be any animal lacking a backbone or a notochord.
What problems could take place if all the fish eggs survived to grow into adult fish?
Well it is very unlikely for all of the fish's eggs to survive to adult but if they do they can fight so if i were you i would separate them.
Where would you find the ventral heart in a chordate?
In all higher Chordates heart is found in thorax .
Who would win an American aligator or Cuban croc?
Though physical encounters would be highly unlikely - the american alligator would probably be the victor. Adult specimens are approximately twice the size of their Cuban counterparts.
Difference between notochord and vertebral coloum?
1) The notochord is the defining structure of the phylum Chordata, which includes all vertebrates. In its "mature" state, the notochord is a rod of large cells constrained by a thick extracellular sheath and positioned between the developing spinal cord and gut. Turgor pressure generated by notochord cells exerted against the sheath gives the notochord stiffness, imparting the mechanical properties required for one of its main functions as the central axial skeletal element of the developing embryo. 2) The notochord exists transiently during the life of most vertebrates. During its short life, however, the notochord plays another critical role for developing embryos,.producing a variety of secreted growth factors, such as Sonic hedgehog, which instruct surrounding tissues to acquire particular differentiated fates. A number of embryological experiments, for example, tell us that, without notochord-derived signals, motorneurons in the spinal cord would not form, the pancreas insulin-producing cell would not differentiate, and the body muscles would not be produced properly. Without the axial skeletal support of the notochord, many lower vertebrate larvae, such as fish fry and tadpoles, become severely shortened and cannot swim or feed properly. Thus many of the mutations affecting zebrafish notochord development are named after the seven dwarves.
Can a 19year old be covered on parents health insurance?
It depends on the wording of the policy, but if the policy was a family policy it would not normally cover adult children (normally those 18 or over would be adult) and thus it is unlikely that a 19year old would be covered. The 19year old would need separate health insurance cover of his/her own.
Would an adult ribbon snake eat a baby ribbon snake if left in the same cage?
This is unlikely but the possibility exists. It is important that they are kept separate at feeding time and that there is plenty of space in the enclosure.
Can a human adult weigh 799 oz?
There are 16 ounces to a pound. Divide 799 by 16 and you get 49.94 pounds. It is highly unlikely. Even a Little Person would weigh more than that.
How do you make a sentence with unlikely?
It is unlikely that you are older than 8, because otherwise you would know how to use unlikely in a sentence. :)
Would a clan of three adult cats kill a kitten new to your home?
It is very unlikely. Most adult cats don't kill kittens. Adult cats are territorial and want their space. Otherwise, they usually avoid the kitten. Normally adult cats will hiss and growl at the kitten. Then pop the kitten with its paw. Then go away. Some adult cats will adopt the kitten. I have an adult female cat that adopts kittens as her own. She lets the kitten nurse, she cleans it and plays with it.
