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 embryo  development" yields a wealth of items from photos to illustrations.  If more specific information about the embryonic development of a  particular animal is of interest, adding that information to the  search "photos of (horse)...
The human embryo is protected from the environment because it  develops in the uterus.   It receives nutritional support from the mother and is protected by  her immune system.
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.
Parthenogenesis. The wikipedia site associated with answers has a  good page on this phenomenon as well as on similar reproductive  processes that result in offspring with the DNA of only the female  parent 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 viable  offspring although they are not fertile. Autosomal aneuploidies are  always 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 birds...
Which organism is not a consumer?
is a embryo a organism at its early age
The development of a fruit fly is egg to embyro and then through  three larval stages before it pupates and develops into an adult. A  larva is an undeveloped worm like eating machine that in no way  resembles the adult.   The development of frogs varies by species but the most well known ...
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 among  animals with backbones. This will reveal the symmetry of the embryo  which 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.
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?
Posterior placenta is when the placenta is located at the back of  the motherÃ?s uterus. Placenta praevia means the placenta has not  moved 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 of...
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...
platypus and spinney anteater
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 this  because it took me forever to find it    f.irst of all the person who answered think is so damb stupid cuz  thats 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 well  as a food supply. As a result, seeds can stay dormant until they're  ready 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 for  lung tissue, a cell or two for the muscle in your ankle etc,  everything you need to become whatever species you are. These cells  copy themselves until they have a mass large enough to function.  These cells continue to copy until...
  * 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 humans, gender is determined by the x and y chromosomes, with xxbeing a genetic female and xy being a genetic male

There are two main branches of Biology. Zoology and Botany. However  there are many subdivisions and supplementary disciplines such as  ecology and mycology.
Human and chick embryos are quite similar. Heart action and eye  slits begin at approximately the same time in chicken and human  gestation.
By nutrients contained in the uterine lining.
Ther is no such thing as period of embryo .
After cleavage a zygote forms embryo until it is born or hatched .
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 out  and 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.
Type your answer here... they are developed in the posterior abdominal wall at the level of l1 (lumbar) vertebra.
ya it smells like booty(;
No. With the odd exception (eg. mature red blood cells because they have no nucleus) every cell in a multicellular organism has the same set of genes. What gives the cells their different character, their phenotype, is which of these genes are expressed at any given time.
Fetus is name given to human embryo after it is recognizable as human embryo .
Whatever the mother eats becomes the food supply for the baby. Maythe food is broken down into small particles for the embryo.
In some animals the embryo develops inside the egg. In mammals, the egg and sperm become an embryo that develops into a life form.
all chordates - novanet now all you guys get back to work :D
they cut 1 of a human
The higher number of embryos produces, the lower their chances of  survival.
