Which of the following scenarios involves the introduction of a potentially invasive species?The migration of spiders in fruit shipped to the United States from South AmericaThe escape of rattlesnakes from a zoo exhibitPicking flowers while on vacation in California and planting them in your garden in Texas I and II only I and III only II and III only I, II, and III

The scenarios that involve the introduction of a potentially invasive species are:

1. The migration of spiders in fruit shipped to the United States from South America: This scenario involves the introduction of a potentially invasive species because the spiders, which are not native to the United States, are being brought into the country. If these spiders were to establish a population, they could potentially disrupt local ecosystems.

2. The escape of rattlesnakes from a zoo exhibit: This scenario does not involve the introduction of a potentially invasive species. While the rattlesnakes may not be native to the area around the zoo, they are still within their native range in the United States. Therefore, they would not be considered an invasive species.

3. Picking flowers while on vacation in California and planting them in your garden in Texas: This scenario involves the introduction of a potentially invasive species. The flowers, which are native to California, are being planted in Texas. If these flowers were to spread beyond the garden, they could potentially disrupt local ecosystems.

Therefore, the correct answer is "I and III only".
