What are some of the applications of animal reproduction and development in the real world?
Step by step
Solved in 3 steps
- Do all of them please 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:What is biological constraints ?What are some unique complications that can arise during specific life stages in organisms, and how do these complications impact their overall survival and reproductive success?
- What Are the Principles of Animal Development?Animal research is a necessary practice in the world of medical research, allowing scientists to develop life-saving interventions and to spot catastrophic problems before new techniques or products make their way to actual patients. However, this does not mean that we should deny that there are serious ethical issues involved. Animal testing is not a pretty or pleasant process. It causes pain and suffering to animal subjects, and legitimate cases of abuse have been uncovered by animal rights groups. Consequently, the practice should be tightly regulated, and alternative methods should be employed whenever possible. • Discuss a specific research study involving animals that had ethical issues. • What were the ethical issues involved? • What could have been done to conduct the research study differently to avoid these ethical issues?Answer 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. Is parental care of a species a factor that affects embryological development? If so, how?
- Which of the following statements best describes the advantage of sexual reproduction in organisms? It reduces genetic variation, which may be useful in the future. It prevents adaptation in a changing environment. It yields offspring with novel combinations of traits. It eliminates the possibility of harmful traits being passed on. tnf: Which of the following statements best describes the functions of villi and microvilli? Villi and microvilli form the inner layer of epithelial tissue in the small intestine and increase the absorption of nutrients from chyme. Villi and microvilli absorb food through the small intestine via smooth muscle contractions called peristalsis. Villi and microvilli increase the surface area of the small intestine, which increases the absorption of nutrients by diffusion. Villi and microvilli increase the surface area of the small intestine, which aids in the absorption of bile salts and vitamin B12.What is the food needed by dogs? How do they obtain their food? How do they perform reproduction? How does development takes place in dogs?Which of the following is true regarding the use of animal models in health research? Primates are the most common animal model used in medical research in Canada Rats fed a high fat diet are a good model to study lifestyle-induced effects on metabolism and health Drosophila cannot be used as a model for human genetics due to extreme differences in emergent properties between drosophila and humans Two of the above are true
