Why do all vertebrate's have very similar forms during development?
The Genes that control development in different vertebrates are only slightly different from each other
What is embryonic development of the amphibian egg?
A frog egg is 1.6 million times larger than a single frog cell. The egg turns into a tadpole during embryonic development.
Where do testes form during embryonic development in a pig?
The testes of a fetal pig develop in the internal reproductive system. The reproductive system which has two scrotal sacs if the pig is old enough.
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.
What vertebrate group is a lizard in?
All vertebrates are members of the phylum Chordata, but not all creatures in Chordata are vertebrates. There are three subphylums in Chordata. Two of them are invertebrates - Urochordata (tunicates) and Cephalachordata (lancelets), while the third is Vertebrata (vertebrates). This phylum includes all animals which have a hollow nerve cord and a notochord at some stage during their development. In the case of vertebrates, the notochord is present in the embryo, and develops into the vertebral body. In the tunicates, the adult form no longer has the notochord. Another characteristic they share is that, at some stage during their lives, they have pharyngeal grooves and pouches that develop into other essential parts of their anatomy (many textbooks still state that all vertebrate embryos have gill slits, but there has been a great deal of development in the science of embryology to refute this claim). Chordates all have a post-anal tail, which means an extension of the notochord and nerve chord behind the anus, although this feature is no longer present in the mature forms of some creatures such as frogs, and some mammals such as people. Chordates also have a closed circulatory system, although not all Chordates have an actual heart like the vertebrate Chordates do.
Do vertebrates have a notochord during early embryonic development?
True
What tells cells to differentiate during embryonic development?
The inheritance of an organism tells cells to differentiate during embryonic development.
During embryonic development of animals tissue layers form This process of embryonic tissue development is called?
germination
When do cells take on their unique characteristics?
during embryonic development
Do tunicates and lanceletes have back bones?
No. They are both chordates, which means during embryonic development they have a notochord, the same as vertebrates. This does not persist in tunicates, but it does in lancelets (adults still have a notochord). Neither tunicates or lancelets have a backbone.
When does Anencephaly occur?
It occurs during the first month of embryonic development
What happens to genes during embryonic development?
They are replicated countless times.
Do sharks have notochords?
Sharks don't have notochords because they are vertebrates. All vertebrates go through an embryonic stage where a notochord is present, but then during development in the womb, this structure is replaced with a spine. The remnants of a notochord in these species can be found as the nucleus pulposus, a jelly-like center of intervertebral discs.
When the skull is membranous during embryonic development does the brain have room to grow?
False
What is an agrin?
An agrin is a protein involved in the neuromuscular junctions during embryonic development.
Which are the two body cavities that form during embryonic development?
Coelom and Peritoneal cavity
Genes located in different regions of the body during embryonic development may be what?
turned on and off
