I believe that all the above are ethical concerns regarding genetic engineering. Ethics is the study of moral or socially acceptable behavior. With the advent of genetic engineering and the ability to modify the genome of various organs, many ethical questions arise concerning the various scenarios and possibilities. There are many ethical concerns regarding genetic engineering in plants, animals, and humans. One of the ethical concerns regarding genetically modified plants used for food is whether the nutritional value will be sacrificed in favor of a higher yield or drought resistantancy.
The answer is negative controls. These are groups where no phenomenon is probable. They ensure that there is no effect when there should be no effect. Where there are only two possible outcomes, e.g. positive or negative, if the treatment group and the negative control both produce a negative result, it can be concluded that the treatment had no effect. If the negative control group and the treatment group both yield a positive result, it can be inferred that a puzzling variable is involved in the occurrence under study, and the positive results are not only due to the treatment. In other examples, outcomes might be measured as lengths, times, percentages, and so forth.
The answer is true. They cannot only replicate themselves within cells, but they cannot outside of a cell.
