Refer to the figure.        This Walter climate diagram suggests which type of biome characterized by which type of plants?

Which interaction would be considered a mutualism?

The branches and canopy of fig trees in tropical rainforests provide habitat for several thousand animal species, including insects, reptiles, birds, and rodents. Their fruit serves as a food source for many species during times of the year when other fruit is scarce. These fruit-eating species in turn provide prey for many different predator species. The benefits provided by fig trees suggest that, in the rainforest, they serve as

After mitosis, the chromosome number of a daughter cell is _______ the parent cell’s.

Rising global temperatures increase the rate of evaporation. The warmer air also holds more moisture. These changing factors are most likely to directly affect which process in the hydrologic cycle?

Refer to the graphs.        Based on the graphs, which conclusion can reasonably be drawn about future extinctions?

Compared with related species, members of a newly-discovered beetle species are larger, stronger, and faster, and they have stronger jaws. These characteristics suggest that the new species most likely feeds on

Monoecious organisms

Some invasive species carry pathogens or parasites with them. Scientists think this might be one reason why some introduced species become invasive. Carrying pathogens or parasites might make an invading species more successful if the invading pathogen or parasite

One strategy considered for preventing introduction of invasive species is deoxygenating ballast water. This strategy is
