Question

3 multiple choice 20 points which technique is often used to create genetically modified crops? gene splicing selective breeding natural pollination crop rotation 4 multiple choice 20 points what is one ethical concern often discussed about gmos crops? they require more water usage. they may affect biodiversity and natural ecosystems. they are always cheaper to produce. they grow slower than traditional crops.

Explanation:

For question 3, gene splicing is a genetic - engineering technique used to create genetically modified crops by inserting or altering genes. Selective breeding is a traditional method, natural pollination is a natural process for plant reproduction, and crop rotation is an agricultural practice for soil management.
For question 4, one of the major ethical concerns about GMO crops is their potential impact on biodiversity and natural ecosystems. Higher water usage is an environmental - resource concern, lower production cost is an economic aspect, and GMOs generally do not grow slower than traditional crops.

Answer:

1. Gene splicing
2. They may affect biodiversity and natural ecosystems.
