The correct answer is "all the above". This is because both frost-resistant strawberries and Bt "caterpillar killing" corn are examples of genetically modified organisms (GMOs). GMOs are organisms whose genetic material has been altered using genetic engineering techniques. In the case of frost-resistant strawberries, genes from other organisms may have been inserted to make the strawberries more resistant to frost. Similarly, Bt "caterpillar killing" corn has been genetically modified to produce a toxin that kills certain pests. Therefore, both examples given in the question are valid examples of GMOs.

Insects can damage a plant by eating it and spreading plant diseases. When insects feed on plants, they can consume large amounts of plant tissue, causing physical damage. Additionally, some insects act as carriers for plant diseases, spreading pathogens from one plant to another as they move and feed. This can result in the spread of diseases that can weaken or kill plants. Therefore, both eating plants and spreading diseases are ways in which insects can cause damage to plants.

Of each dollar you spend on food, 19% of it goes to the farmer. This means that out of the total amount you spend on food, 19% of it is allocated to the farmers who grow and produce the food. The remaining percentage is likely distributed among other stakeholders in the food supply chain such as processors, packagers, truckers, wholesalers, and marketers.
