The cells are known as stem cells meaning they can become any cell type. The embryo becomes bigger because certain genes in the DNA are activated allowing the cell to divide or produce certain determination factors that will make a stem cell become a neuron, muscle cell, etc.... The embryo grows in size as the stem cells divide repeatedly and then some of the stem cells become actual specific cells.

What happen f the girl always excrete out there egg cell to their vagina?
The way the anatomy of the female reproductive tract is prevents this. The only way it might happen is if the uterus is removed and the ovaries remain. The egg may end in the vagina. If the egg is excreted into the vagina and if fertilized, the embryo would be lost. If some how the embryo attaches to the wall of the uterus, it would also be lost. There is not enough room for it to grow.
Where does the developing fertilised egg cell get its food from?
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.
What will happen if the urethra is removed?
The main thing that will happen if the urethra is removed is that urine will not have a way to exit the body. This primary way the body gets rid of toxins and excessive fluids before they cause harm.
Is it possible to have an uneven split of an embryo?
This was a research done by Hans Spemann, an embryologist of the early 20th century in Germany. His research lead him to conclude that the dorsal and ventral (top and bottom) halves of the embryo were different. The top half contained a certain group of cells that organize development. They are visible on the dorsal surface of a 2-cell-stage embryo. The outcome of his constriction experiments depended on exactly where this structure was in relation to the constriction. If one half of the constriction contained the entire structure, it would develop into an embryo that could live and the other half developed into the belly-piece. If the structure was evenly split during the constriction, the result was twin, including Siamese twin, embryos. If it was split unevenly, it resulted (in some cases) an embryo with two heads (a Siamese twin). He also inadvertently discovered a way to clone during this process of constricting embryos as they split.
Is cloning humans diffrent procedurally from cloning animals?
The cloning of humans and animals can be done the exact same way for both. The methods that can be used are artificial embryo twinning and somatic cell nuclear transfer.
How does the way that the plant embryo gets its food compare with that of the seedling?
i dont know if its righ orwrong
How does a bear embryo develop?
The same way that a human embryo or any other mammalian embryo does.
How do you get bigger breast without pills and surgey?
The only way is to gain a lot of weight. But they won't be the only thing that gets bigger.
What needs to happen before the plant embryo can push its way out the seed coat?
The embryo is the baby plant. It has an embryo root to push its way eventually out of the seed coat, and embryo stem, and embryo leaves which will later start food production.
What is the main way the plant gets water for it petals?
through the roots
What happens when a embryo splits?
A twin is on the way
What affect is an increasing population creating in relation to greenhouse gases?
Think of it this way: The bigger the population gets, the more resources they use, the more pollution they emit and the bigger this problem gets. Reduce the population, and you reduce the levels of greenhouse gases in the atmospere.
Do volcanoes work in the same way?
yes because every volcano explodes and gets bigger and bigger until it is enormous. is the way we used the volcano and it can erupt anywhere or any second. overall a volcano can explode more or less than 300.
Is streching your ears painful?

Does the placenta supply food for the developing embryo?
everything. It is the way the fetus gets all it needs from the mother and disposes of of practically all waste except heat. The fetus gets nutrients and oxygen from the placenta and the placenta filters the fetus' blood and takes out wastes
What are the disadvantages of embryo transplant?
by miscarriage
What if your penis when erects only gets half an inch bigger?
A percentage of men are just built that way. You will get hard and some increase in diameter but little increase in length. That's just the way it is and you shouldn't worry about it.
