Embryology is a branch of biology. It involves the study of the embryo from conception until the point at which the zygote becomes a fetus.
The little black dot in the egg is the part that grows into an embryo.
A quick internet search using the phrase "photos of embryodevelopment" yields a wealth of items from photos to illustrations.If more specific information about the embryonic development of aparticular animal is of interest, adding that information to thesearch "photos of (horse) embryonic...
The human embryo is protected from the environment because itdevelops in the uterus. It receives nutritional support from the mother and is protected byher immune system.
It would be more appropriate to say that all vertebrate embryosdevelop pharyngeal gill slits during one of the many phasesin their embryonic development. This is because while gills arespecifically present in fishes, pharyngeal gill slits are a generalchordate feature.
There is no food supply for seeds but there is a food supply for animals that eat seeds is called food seed supply.
Parthenogenesis. The wikipedia site associated with answers has agood page on this phenomenon as well as on similar reproductiveprocesses that result in offspring with the DNA of only the femaleparent but still require mating.
i need the same answer as well D;
i think it is called. Pregnentcy or pregnent woman
Food is definitely one structure which diffuses from the mother's blood to the embryo. I need to find out another one to answer my question?
As it has food already coming from the person having the baby.
Female embryos with a single X chromosome can develop into viableoffspring although they are not fertile. Autosomal aneuploidies arealways lethal.
During development, embryos of multiple groups of animals exhibit similar characteristics, but may change as they grow. This supports the idea that all of today's organisms share a common ancestor. 'An example is bird limbs. Birds are tetrapods, all of which have five-digit limbs, but adult...
Which organism is not a consumer?
The development of a fruit fly is egg to embyro and then throughthree larval stages before it pupates and develops into an adult. Alarva is an undeveloped worm like eating machine that in no wayresembles the adult. The development of frogs varies by species but the most well knowncycle is egg to...
they look the same when you take x-rays so it most mean the we came from the same organism improved ans: by monitoring how and what an embryo grows as it matures, you can see a lot of things that you cannot see in a fully grown animal, for instance, human embryos have a tail at certain stages in...
A study of the embryos could help show the relationships amonganimals with backbones. This will reveal the symmetry of the embryowhich can be used for classification purposes.
The cells in a developing embryo differentiate so that the cells develop different sructures so they can perform different functions.
The stages of development of the embryos of certain organisms are extremely similar, a fact that suggests the organisms had common ancestors.
It provides aqueous medium and protection .
Before a cell divides, its nucleus must divide, in order to pass on this information to both daughter cells. In higher plants and animals a process known as mitosis ensures that chromosomes, after dividing, are distributed evenly between the MORE?
Continuation of the species. The embryo will grow into a chick in 21 days.
Posterior placenta is when the placenta is located at the back ofthe motherÃ?s uterus. Placenta praevia means the placenta has notmoved up towards the top of the uterus to get ready for birth.Grade 2 means the placenta is near the cervix but not blocking it.
I am doing some homework on reptiles and i think that is the case.
Ectoderm: Brain and medulla spinalis, epidermis (outermost layer of skin), eye and part of ear, most bones and cartilages of skull, pigment cells, teeth, meninges, and so called conotruncal sept which is crucial in development of heart. Endoderm: Gastrointestinal tract, bladder and urethra, part...
Yes, however in vivo transplants generally occur quite early afterconception when the conceptus is still mobile within the donor'suterus. in vitro fertilization, where the egg is fertilized outsideof the womb, is the more common procedure as it is easier to makean effective transfer from the donor...
the amnion is a fluid-filled sac that will protect the embryo from mechanical shock.
Embryos get their nutrients through the placenta.
The economic advantages of cloning and transplanting cattle embryos is the you can mass produce cows for succulent beef also you can provide wonderful creamy milk which will give your country and family a more rich and wealthy life. The disadvantages of cloning is that the beef could become toxic if...
As all animals including chicken come form the same domain of life eucariota they have similar characteristics. as in principle the embrio of animals forms the same way and seperates its development at a certin stage acording to the different specie. the main reson for this similarity in development...
There are not many ethical issues with embryo cloning in cattle but one of them is that it's not natural.
When people say that babies get their food from what their mother eat, their wrong that's just a myth. The developing embryo gets its food from the umbilical cord because it transfers blood and liquids to the developing embryo and that's how they get their food.
I am not sure if this is a correct answer to your question, because i am no expert on fowl, but I am not aware of birds ever having gill slits in there formation. Humans have slits that have been misconstrued to be gill slits but those are there to help with the formation of your neck and ears. I...

The fluid-filled cavity in an embryo, in the early embryonic stage, is called a blastocoele , or blastocyst cavity ; this is perhaps the cavity you're referring to. See the link below for more information on the human embryo.
What do you mean by explain? Advise what it is that you need explaining on.
just look up ectoderm by itself you will find it
Hey there! OK well unlike the amphibian the reptile's eggs have a shell and membranes that protect the embryo and keep it from drying out:-). Hope you found this helpfull!
the fish will develop at a normal rate for approximately 5 week and then it will grow legs and arms and get into a fight with a shark
It is called the amniotic. I am sure people out there needs thisbecause it took me forever to find it f.irst of all the person who answered think is so damb stupid cuzthats not the answers that person is a dick head
The amniotic sac is the sac in which the fetus develops in amniotes. Its wall is the amnion, the inner of the two fetal membranes. It encloses the amniotic cavity and the embryo.
The placenta is where the material between mother and child, like nutrients and oxygen, travel from one to another.
A spore has a seed coat that provides it with protection, as wellas a food supply. As a result, seeds can stay dormant until they'reready to germinate.
Humans don't ever really look very pig like during development.There are early periods in development where pig and human embryoslook similar but by the time human and pig fetuses have developedto the point of looking even somewhat like their future selves theyin no way resemble each other.
The ectoderm is the germ layer covering the surface of the embryo and develops into the outer covering of the animal (in our case, our skin) and in some phyla, the nervous system. The mesoderm forms the muscles and most other organs between the digestive tract and the outer covering of the animal...
A living anything needs food and lots of living things need oxygen. So, yes, embryos need food and oxygen too.

In 72 hours the tail bud and allantois vitelline vein, wing bud, also the nasal pit appears, all the things that are not present in the 48 hour chick.
The cells of the embryo split up into groups; a or two cell forlung tissue, a cell or two for the muscle in your ankle etc,everything you need to become whatever species you are. These cellscopy themselves until they have a mass large enough to function.These cells continue to copy until they are...
Cytoplasmic embryo or cybrid: where a human cell is inserted into an animal's egg that has been stripped of nearly all its nuclear DNA. The embryo would be 99.9 per cent human and 0.1 per cent animal.
the hollow ball of cells is called the Blastocyst. At which point this occurs depends on the particular species.
In protostome ("first mouth") the blastopore, or the first opening formed becomes the mouth. In deuterostomes ("second mouth"), the blastopore forms the anus and the mouth develops from a second opening.

In plants embryo develops in new seedling and in animals it develops into feotus which later develops into baby
No, if you put it back in its nest the mother will kick it outand it will die overnight.
When you crack open an egg you will see the yellow part called the yolk. The yolk is surrounded by the clear white substance called albumen. As the embryo develops within the shell, it is protected by the albumen.
the organ i believe your talking about is the placenta and the thing that connects is a umbilical cord.
It reduces the posibility of a child haveing a poor quality of life.
