Genetically Modified Organisms (GMOs) - Unsolved Practice Set

Q1. A Genetically Modified Organism (GMO) is defined as an organism:

1. Bred using only traditional cross-pollination methods
2. Whose genes have been altered using genetic engineering techniques
3. That has never been exposed to any environmental change
4. That reproduces asexually

Q2. Genetic modification of an organism is generally carried out to:

1. Introduce a desirable trait not naturally present, or to alter an existing trait
2. Remove all genetic material from the organism
3. Prevent the organism from reproducing at all
4. Reduce the organism's overall fitness

Q3. Which of the following is an example of a genetically modified organism?

1. A wild, unmodified rice plant
2. A crop plant genetically engineered to resist a specific insect pest
3. A naturally occurring bacterium with no genetic alteration
4. A hybrid plant bred purely through traditional cross-pollination

Q4. GM technology has been used to develop crops with improved:

1. Susceptibility to pests and diseases
2. Tolerance to environmental stresses, pest resistance, and nutritional value
3. Complete inability to grow
4. Reduced yield

Q5. One general concern often raised regarding GMOs is related to:

1. Their complete absence of any economic value
2. Potential ecological and health impacts that require careful evaluation
3. Their inability to be regulated at all
4. Their guaranteed harm in every case
