Two ethical issues of using Biotechnology are Affordability and Privacy. Two social issues of Biotechnology are Harm to the environment and Bio-terrorism.
<u>EXPLANATION: </u>
- The most concerning ethical issue of using biotechnology is the cost and access to new treatments.
- The drugs that break clots that cause heart attacks, for example, are extremely expensive and so the common people cannot afford them.
- The second ethical issue is Privacy.
- The technology can decode the human genome which might reveal the future health information of a person.
- The first social issue of using biotechnology is the harm to the environment.
- It is not sure how will the ecosystem react when a new organism is introduced in the ecosystem.
- Another social issue is that terrorists might make new superbugs or infectious viruses, using biotechnology, which might not have any cure.
Nitrogen. The acronym CHON is an easy was to remember these four biomolecules that make up life. Carbon, Hydrogen, Oxygen and Nitrogen are essential for life as we know it. Nitrogen plays a critical role in the construction of proteins and DNA. And Nitrogen is considered essential in the overall process of photosynthesis for the production of chlorophyll in plants.
1.A control group is important to an experiment because it allows you to eliminate and isolate those variables.
2. Controlling variables is important because slight variations to the experiment set up could affect the outcome significantly
Hope this helps :)
