Solved by a verified expert:Unit 1 Discussion Board 1: ExperimentAs scientists and doing an experiment, you need to have an experimental group and a control group for testing a hypothesis. If you were a scientist, and with the knowledge you have, what kind of hypothesis would you test? Who would be in your control/experimental group?Unit 1 Discussion Board 2: WaterWhat is water, and why is water essential to life? List the three properties of water and how they are useful to many species on earth.Unit 2 Discussion Board: Binge DrinkingBinge drinking is the most serious drug problem on college campuses in the United States. What organ does ethanol effect? What long term health effects, and other related injuries does binge drinking have on college students?Unit 3 Discussion Board 1: CloningEthanol and other fuels manufactured from crops currently cost more than gasoline, but they are renewable energy sources and have fewer emissions. How much of a premium would you pay to drive a vehicle that runs on biofuels?Unit 3 Discussion Board 2: BiofuelsShould animal cloning be banned? Do you feel that in the future, as research progresses in the field of cloning, that a human may be cloned?Unit 4 DB: Henrietta LacksIn 1950, Henrietta Lacks was suffering with Cervical cancer. The resident who was treating Henrietta took a sample from her cervix, and this sample was used to develop the HeLa cell line. The HeLa cell line is an immortal cell line which helped research the different polio viruses and lead to the development of vaccines for polio, amongst other medical advances. The ethical dilemma that arises from this great discovery is that no one asked Henrietta for permission to take a sample and use her cells for research. Henrietta died at the age of 31 because her runaway cell divisions killed her. Her cervical cancer spread quickly to other organs. However, her legacy lives on, as her cells are still dividing and being used-60 years after she died. No one knew, until 25 years after she died, that her cells were the HeLa cell line which has advanced cancer research to where it is today, as well as other medical treatment research. The family has not received any compensation to date. It is now illegal to sell oneâ€™s own organs or tissues, but no one is under a legal obligation to share profits reaped from research on a patientâ€™s tissues-or cell lines derived from them. Should the family of Henrietta Lacks be compensated? Her cells are still being sold worldwide.Unit 5 DB1: Prenatal vs preimplantation diagnosisWhat is prenatal diagnosis vs preimplantation diagnosis? What are their similarities and differences? How do you personally feel the availability of prenatal and preimplantation diagnosis changes our ability to reproduce?Unit 5 DB2: GMOsGenetically modified food do not have to be labeled as such, even though packaged foods in the United States must be labeled with nutritional information. Should food producers and distributers be required to identify products made from GMO plants or livestock?Unit 6 DB: Antibiotic resistant bacteriaThe advances in biotechnology, genetic research, and pharmaceutical discoveries have lead to the development of super resistant bacteria and animals to drugs. There are antibiotic resistant strains of bacteria and there is a rise in pests that are resistant to poisons developed to destroy them. What can we do to protect ourselves from resistant strains of bacteria, and how can we control pests, like rats and mice, that are now becoming â€˜immuneâ€™ to the poisons developed to keep them under control? Provide the resources and websites you used.Unit 7 DB1: DrugsDeveloping drugs for fighting AIDS is expensive. The drugs are expensive and protected by patents. Some insurance companies do not cover the cost of the drugs. Some people choose to pay out of pocket to protect their identity. How do you feel about patenting medicine that can save lives, and can you think of ways where protecting your identity would be important?Unit 7 DB2: PaperLogging removes trees and disrupts relationships between plants and soil fungi. Removing trees for building and for paper products can destroy populations that may take a long time to recover, if not recover at all. Recycling is a benefit for paper products, but can add to the expense of the paper product. Would you be willing to pay more for recycled paper, and magazines printed on recycled paper? Why or why not?Unit 8 DB: Population ControlEncouraging hunting is the least expensive way to reduce the number of wild species (Canadian geese and white tailed deer, for example) that has become a nuisance due to its increased numbers. Do you favor hunting as a way to control the size of a population?
