Final answer:
Reyna is likely to encounter conifer trees like evergreen spruce, pine, fir, and juniper on her snowy mountain camping trip, rather than palm trees which thrive in warm climates.
Step-by-step explanation:
Given the conditions described, with snowfall and a mountainous region, the types of trees that Reyna is likely to see on her camping trip are conifer trees. Conifer trees, also called evergreens, are well-adapted to cold environments due to their needle-shaped leaves and conical shape, which help them endure and shed snow. Examples of conifer trees include the evergreen spruce, pine, fir, and the juniper. These evergreen trees can photosynthesize earlier in the spring than deciduous trees because they retain their foliage year-round, allowing them to take advantage of the sun's energy as soon as it becomes strong enough. Palm trees, on the other hand, are associated with warm, tropical climates and are unlikely to be found in cold, snowy mountain regions where Reyna and her foster mother are camping.
