True/False: 24) Studies of invertebrate and vertebrate development suggest that there is a universal body plan for bilateral animal development.Answer: 25) One of the four overlapping stages in animal development is apoptosisAnswer: 26) The primary interest of genetic research into stem cells is the desire to be able to clone a human being.Answer: 27) Unipotent cells may differentiate into all other cell types of the body.Answer: 28) The reduction of pollutants in the environment by microorganisms is called biodegradation.Answer: 29) A transgenic organism has recombinant DNA integrated into its genome.Answer: 30) An organism that can be regenerated by somatic cells is called multipotent.Answer:
People could observe the development of an embryo before they had the tools to see cells and parts of cells such as DNA. How they explained the development from embryo to organism and how would the discovery of DNA and how DNA "works" have changed how scientists could research development?

- Using the space below please address the items below as they relate to human embryology; a) discuss when the germ layers of human development begin to form, explain how each originates, explain what each will differentiate into, and what happens to each layer immediately after formation b) distinguish the developmental differences between a 20 day old embryo and a 4wk embryo in humans.arrow_forwardAnswer the following: More recently evolved organisms have modified the stages of embryological development. Would you expect early or late stages to be modified the most? Why? The basic stages of embryological development are remarkably similar for a wide range of organisms. How would you explain such consistency? As cells invaginate and move about, do they “know” where they are? If not, how is movement controlled? If so, how do they perceive their position.
