What are the differences between embryo and adult stem cells?
Adult stem cells are harvested from newborn's cord blood or human bone marrow while embryo stem cells come from the inner cell mass of a human embryo. No fetus is killed to use the stem cells, but the embryo cannot function and must be destroyed without a inner cell mass.
What is a plant structure in a seed plant that contains an egg cell?
a seed plant embryo is part of a seed, consisting of precursor tissues for the leaves, stem (see hypocotyl), and root (see radicle), as well as one or more cotyledons. Once the embryo begins to germinate - grow out from the seed - it is called a seedling (plantlet). Plants that do not produce seeds, but do produce an embryo, include the bryophytes and ferns. In these plants, the embryo is a young plant that grows attached to a parental gametophyte.
What are facts about reproduction?
Cells can reproduce (I think) about 10,000 cells a second.
How many sex chromosomes does a sperm carry?
Each parent donates 23 chromosomes to fertilization process however only the male can determin the sex.
Do the cells of the receptor organ in the inner ear regenerate?
No, once damaged the cells will scar but not regenerate.
If parts of the embryo is still inside you can you still be pregnant?
You will get infection if the remains are not removed. And no, once the embryo died the pregnancy ended.
What happens to the embryo when the hen lays the egg?
When a hen lays a fertilized egg, there is no embryo inside. Embryo's only start to form once they are incubated.
Does the brain reproduce brain cells?
NO. The brain cells and other nerve cells once formed in the embryo do not divide further in the entire lifetime. Once dead they are not replace. No matter what you do even medicine wont make new ones. Nothing can remake the cells and the cells do not get cut in half to make two.
When does organogenesis occur?
Organogenesis is the process by which a mass of cells in a developing embryo differentiates and develops into a functioning organ. In the embryo, all cells are basically stem cells and all alike. Once the process of organogenesis takes place and the beginnings of specialized organs form, the fetal stage begins.
What happens to the seed coat of a bean embryo as it grows?
Once the bean plant starts to develop its first pair of leaves, the seed coat will be shed.
What are the differences between embryo and adult stem cells?
Adult stem cells are harvested from newborn's cord blood or human bone marrow while embryo stem cells come from the inner cell mass of a human embryo. No fetus is killed to use the stem cells, but the embryo cannot function and must be destroyed without a inner cell mass.
What organ attaches the embryo to the uterus?
Once the egg is fertilized the outer cells of the blastocyst (Blastocyst is the early stage in the developing embryo) will absorb nutrients from your endometrium (which is the wall of the uterus). The Blastocyst completes attachment to the uterus about 7 days after fertilization. It burrows into the walll of the uterus and adheres; some women experience spotting during this stage. The outer cells of the blastocyst will become the placenta and umbilical cord. That is what attaches the embryo to the uterus. Hope this helps!
What is an embryo called once its skeleton has formed?
Fetus
Why does meiosis happen twice?
Meiosis happens twice to create FOUR non-identical cells. If it only happened once, only TWO non-identical cells would be made. When it happens twice, FOUR non-identical cells are made.
Why is the growth of the embryo different from the growth of the fetus?
Once the zygote becomes an embryo it starts developing all of its organs, nervous system etc. then after 8 weeks of development everything is there so it becomes a fetus, and the fetus just grows bigger.
How are you related to the children of your first cousin once removed?
The nephews of your first cousin once removed, like the children of your first cousin once removed, are your first cousins twice removed.
What do you call your first cousin once removed's child?
The child of your first cousin, once removed, is your first cousin, twice removed, if your first cousin once removed is the child of your first cousin. If your first cousin once removed in the first cousin of one of your parents, the child is your second cousin.
