Final answer:
The outcome regarding wet and dry adapted plant species is: drought-resistant plants are expected to thrive in warm climates, while other species might decline.
Step-by-step explanation:
The question pertains to the predicted outcomes of an experiment on different plant species' adaptation to climate conditions. In the context of climate change, researchers have been examining the geographic distribution and phenology of plants, which indicates how temperature and precipitation influence their life cycle events, such as flowering.
Based on the provided information, the correct answer would be option d, which states: "Plant species that are drought-resistant would thrive in warm temperatures whereas other species would decline in number in such a climate." This is because drought-resistant species have adaptations that allow them to manage better under conditions of low water availability, which are more likely to occur in warmer climates.
