The two correct answers that relate to how global warming alters the albedo of the Arctic are:
1. **Melting sea ice to reveal darker water** - Sea ice has a high albedo, reflecting much of the sunlight that hits it. When sea ice melts, it exposes the darker ocean water beneath, which absorbs more sunlight, thereby decreasing the overall albedo of the region and contributing to further warming.
2. **Replacing tundra with more rapid growth** - As temperatures rise, areas that were previously tundra may transition to different ecosystems, such as shrubs or forests, which can have a different albedo. Typically, these new ecosystems may have a lower albedo than the reflective tundra, further altering the heat absorption characteristics of the area.
The other options, such as changing migration patterns for sea life, do not directly relate to changes in albedo.
