Questions: Question 1 1 pts Genetically Modified Organisms (GMO)? Are organisms hat have been physically altered through selective breeding or cross-breeding with unrelated species. Are organisms whose genetic material has been altered using genetic engineering techniques. Are organisms that have undergone natural mutations due to environmental factors or radiation exposure, resulting in changes to their genetic makeup. Next

The answer is the second one: Are organisms whose genetic material has been altered using genetic engineering techniques.

Explanation:

1. "Are organisms that have been physically altered through selective breeding or cross-breeding with unrelated species." - This describes traditional breeding methods, not genetic modification.
2. "Are organisms whose genetic material has been altered using genetic engineering techniques." - This is the correct definition of GMOs, as it involves direct manipulation of an organism's DNA using biotechnology.
3. "Are organisms that have undergone natural mutations due to environmental factors or radiation exposure, resulting in changes to their genetic makeup." - This describes natural mutations, not genetic modification through engineering techniques.

Summary: Genetically Modified Organisms (GMOs) are organisms whose genetic material has been altered using genetic engineering techniques.
