Question

despite antarcticas extreme cold, dryness, and limited sunlight, two flowering plants thrive: antarctic hair grass and antarctic pearlwort. the hair grass features long, thin leaves, while the pearlwort has bright yellow blooms. both of these plants possess strong roots, capable of withstanding harsh antarctic winds. hair grass and pearlwort also have a vascular system. this internal structure takes up nutrients from the antarctic soil and distributes them to the plants stems and leaves.
these traits reveal how hair grass successfully competes with pearlwort for nutrients.
these traits highlight how antarctic hair grass and pearlwort survive in a difficult environment.
these traits demonstrate how flowering plants dominate the antarctic ecosystem.
these traits suggest that flowering plants recently adapted to the antarctic climate.

Explanation:

The text describes traits like strong roots and vascular systems of Antarctic hair grass and pearlwort. These traits help them survive in the harsh Antarctic environment of extreme cold, dryness, and limited sunlight. It doesn't focus on competition between the two plants, nor do the traits show that flowering plants dominate the Antarctic ecosystem or that they recently adapted.

Answer:

These traits highlight how Antarctic hair grass and pearlwort survive in a difficult environment.
