"Watermelon snow" in Antarctica is caused by a species of photosynthetic green algae that thrives in subzero temperatures (Chlamydomonas nivalis). These algae are also found in high altitude in year-round snowfields. In both locations, UV light levels tend to be high. The reddish-pink color of these algae is due to the presence of carotenoid pigments, which absorb blue light while reflecting red light. Those pigments protect the chloroplast from ultraviolet radiation, as well as absorbing heat, which provides the algae with liquid water as the snow melts around it. This molecular variation in plants illustrates
A) relative fitness because the molecular adaptations in chlorophyll pigments have passed to the next generation
B) innate variability because plants have evolved molecular differences to an environmental stimuli
C) unselective adaptation because plants have evolved molecular differences to adapt to different wavelengths of light
D) inclusive fitness because differences in chlorophyll pigments increase the proliferation of beneficial traits in the population

Atown located beside a river derives a large percentage of its revenues each year from the local logging industry. however, heavy traffic to and from the logging sites has increased pollution and contributed to soil erosion. this has also resulted in the loss of native bird species in the logged forests. which of the following is the most sustainable solution to this problem? protecting certain forested areas to allow the birds to recover relocating the equipment and vehicles to new forests for logging relocating the birds to new forests away from the town introducing new bird species to replace the species that have been lost reducing the number of trucks traveling through the forest by 10 percent
