What else can I help you with?
Do human embryos have gills in the womb?
yes.
What structure do chicken embryos have around them that human embryos do not?
Chickens have an actual shell. The shell along with the embryo is called an egg. Human embryos are inside a females' womb which is made of skin, not keratin like egg shells are.
What are the key differences between a chicken embryo and a human embryo in terms of development and structure?
Chicken embryos and human embryos have key differences in their development and structure. One major difference is that chicken embryos develop outside the mother's body in an egg, while human embryos develop inside the mother's womb. Additionally, the structures of the two embryos differ, with chicken embryos having a yolk sac for nutrition and a hard shell for protection, while human embryos rely on the mother's placenta for nutrition and protection. Overall, these differences reflect the unique evolutionary adaptations of each species for embryonic development.
Do human embryos have tails during development?
Yes, human embryos do have tails during early development, but they typically disappear as the embryo continues to grow and develop.
Where do human embryos develop in?
Human embryos develop in the uterus, specifically in the lining of the uterus called the endometrium. The fertilized egg implants itself into the endometrial lining where it will continue to grow and develop into a fetus.
Which type of system compose of the skeleton of sharks and human embryos?
Cartilage.
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 has the author Marie-Luise Pannke written?
Marie-Luise Pannke has written: 'Der Schutz des extrakorporalen Embryos' -- subject(s): Fertilization in vitro, Human, Frozen human embryos, Human Fertilization in vitro, Law and legislation, Legal status, laws
What is one concern that people have with stem cell research?
The first concern is the destruction of human embryos to extract stem cells. Pro-life activists argue that embryos are a form of life and should be allowed to live. Another argument is that stem cell research can devalue human life as it can lead to consent of reproductive cloning.
What percent of human embryos are spontaneously aborted?
About half of human embryos are spontaneously aborted (that is, with no overt actions taken by the mother or others); see http://www.emcom.ca/health/abortion.shtml for more details.
Fruit Fly embryos and frog embryos differ from each other more than frog embryos and human embryos do What does this tell us about how the three species are related?
Fruit Flies and frog eggs are long-time,well characterized standbys in the lab environment,and specific manipulations allow researches to introduce genes from other organisms into these species
How do embryos demonstrate evolution?
Basically, its the shape of the embryos of vertebrates. If the shape of the embryos are similar, that means they evolved from a common ancestor.More specifically, it's the pattern of nested hierarchies that is found when one compares the embryological developmentof species. Also, developmental atavisms, such as the branchial arches in human embryos, are important clues telling us about our ancestry.
