What are the ten biomes, and what appears to be the most prominent biome in north america, south america, asia, africa, australia, and europe? (since this is an approximation, more than one answer is possible for africa, north america, and asia.)

Well, the ten biomes are:
Tropical Rainforests, Sub-tropical rainforests, savanna, tundra, arctic, boreal forests, conniferous forests, mediterrean, grassland, and desert. I'm doing this off the top of my head, but I know that Africa is mostly savanna. South America is mostly rainforest and Austrailia is mostly desert. The poles North/South are mostly frozen and tundras are the closest lands outside the arctic/anarctic circles. Other places will have a variety of biomes.
Hope this helps!

Ithink option a is correct because you cannot donate a different blood group than yours because it won't match.option a says betsy can donate to mark. they have the same blood group so donation can happen.
