How are vertebrate embryos evidence of evolution?
All vertebrate embryos look roughly the same, showing that they come from a common ancestor.
Do the majority of animal embryos develop inside the mother?
No, the majority of animal embryos develop outside the mother's body. This includes animals such as birds, reptiles, and most fish. Embryos that develop inside the mother's body are found in live-bearing mammals as well as some fish and sharks.
Do embryos search for food outside the egg?

What are three ways that embryo's are protected in sexually reproducing organisms?
Embryos are protected by the physical structures of the reproductive system, such as the uterus in mammals. Embryos are protected by the presence of amniotic fluid or egg membranes that surround and cushion the developing embryo. Embryos are protected by parental care, such as brooding behaviors in birds or the provision of nutrients and a safe environment in mammals.
What might you expect to see when you look at embryos from lions and house cats?

What are the advantages and disadvantages of frozen embryos?
Advantages: Allows possible pregnancy to occur should a woman's reproductive health be compromised (such as through cancer treatments). Allows for In vitro fertilization to occur. Woman can become pregnant later in life. Surrogate pregnancy can result. Disadvantages: It is possible that none of the embryos will survive the thawing process. Expensive.
What are the ethical issues with cloning cattle embryos?
There are not many ethical issues with embryo cloning in cattle but one of them is that it's not natural.
What are the social advantages of cloning and transplanting cattle embryos?
Social Advantages:Mass amounts of animals reproduced.The stem cells in the embryos could be used as treatment for human illnesses.More animals can be reproduced with the desired traits.The animals that have been reproduced this way can be used as a supply of organs for transplanting to humans.Scientists could use this type of cloning to help endangered species.Scientists could also attempt to bring extinct species back to life for example mammoths or dodo birds.Social Disadvantages:If for example a cow was reproduced this way and the cloning was incorrectly carried out at some point, its milk and beef could contain toxic resulting in people becoming seriously ill.If one animal was to be infected and die by an organism because of its genetic make-up, all the other animals that were part of that cloning process will also get infected and die as every clone is genetically identical to each other.
What are the 3 types of reproductive cloning?
The three types of reproductive cloning are embryo cloning, adult DNA cloning, and therapeutic cloning. Embryo cloning involves transferring genetically identical embryos to surrogate mothers. Adult DNA cloning creates an animal that is an exact genetic copy of an existing animal. Therapeutic cloning involves creating embryonic stem cells for research and medical purposes.
Is human cloning legal in the US?
Human cloning is currently not legal in the United States. Federal law prohibits the creation of cloned human embryos for any purpose, including reproduction or research. There are strict regulations in place governing the use of human embryos in scientific research.
What is cloning and transplanting cattle embryos?
It is more known as "Embryo Transfer" than cloning and transplanting embryos of cattle. A cow is flushed so that she will super-ovulate, and artificially inseminated, then she's flushed again so that the embryos can be collected and transferred to donor cows. The donor cows hopefully accept the embryo that they have inserted into them and grow the embryo into a fetus then birthed as a calf. The super-ovulation is a method that encourages natural cloning, even though it's not natural itself by many standards.
What is cloning embryo?
Embryo cloning is when you go through the process of cloning an original embryo
What is Obama's opinion on cloning?
I dug this out of my recycling bin just for you, so enjoy! :) Anyways ... Obama co - sponsored a bill (s. 1520) in 2005 that would allow the cloning of human embryos to be used in research, but prohibited placing them in wombs. Essentially, he's for particle cloning. On the other hand, McCain stated on his campaign website that "opposes the Intentional creation of a human embryos for research purposes"
What are the advantages and disadvantages of embryo transplants?
Advantages of embryo transplants include the ability to improve genetic diversity within a population and increase the number of offspring from superior individuals. However, disadvantages may include the potential for decreased success rates compared to traditional breeding methods, higher costs associated with the procedure, and ethical concerns related to manipulating embryos.
What is the difference between therapeutic and reproductive cloning?
Therapeutic cloning involves creating cloned embryos for the purpose of harvesting stem cells to treat diseases or injuries. Reproductive cloning, on the other hand, aims to create a new organism that is genetically identical to the donor organism.
Statistics about cloning?
4 out of 12 birth mothers died and it took 276 embryos to make Dolly, the first cloned sheep.
Name of Animal Cloning Inventor?
Not really the inventor(s) but the first to clone embryos (Tadpoles in this case) were Thomas King and Robert Briggs.
