The ethics of researching the benefits of using chicken embryos in studying human development is a complex issue that involves balancing scientific advancement with ethical considerations. Some argue that using chicken embryos can provide valuable insights into human development, while others raise concerns about the ethical implications of using animal embryos for research purposes. Ultimately, the ethicality of this research depends on factors such as the potential benefits, the welfare of the animals involved, and adherence to ethical guidelines and regulations.
Scientists use electrons instead of light to see atoms because electrons have a smaller wavelength compared to visible light, enabling them to resolve smaller details of atomic structures. This allows scientists to achieve higher resolution images and better analysis of atomic structures using techniques such as electron microscopy.
It is green, and this is due to their equivolent of hemoglobulin using copper instead iron.
Animal testing is to find out how medicines work and how they help or don't help. Instead of using people for this system they use animals. Animal testing is to find out how medicines work and how they help or don't help. Instead of using people for this system they use animals.
Using the earliest microscopes, scientists observed and described microorganisms like bacteria and protozoa for the first time. They also examined cells, blood cells, and plant tissues in more detail, leading to advancements in the understanding of biology and medicine.
Instead of using antisera for blood grouping , pooled known RBCs are used. the process is serum typing.so serum of patient whose Rbcs are auto aggluting is used.
Non-scientists provide additional sources of data that scientists can use.
