Scientists have cloned more than 20 mammal species. Zhong Zhong & Hua Hua In Jan.2018 much harder/ more complicated Get animals with edited genes and produce animal models that are helpful for medical research and human health. Read paragraphs 4-5. Check answers. P54 5 Potential benefits Moral concerns will lead to cures for various diseases has refreshed the technical possibility of cloning of other species prevent aging save research time reduce the number of animals being tested on producing more accurate results better treatments clones should be treated as objects or individuals clones are inferior some organisations may abuse the technology Read the last paragraph and answer the questions. Einstein’s quote means that science itself cannot be judged as good or bad, because it can only function when it is used by humans. He also indicates that humans need to be careful w ... ...
