blood type B could have a genotype of either BB or BO.
Well, put simply, biology is the study of life. Everything living is organic (everything living decomposes). Biologists study living things which have organic chemistry.
Rain forests are huge carbon sinks, as plants and trees actively remove carbon dioxide from the atmosphere and store the carbon in biomass. This is a vital ecosystem service for counteracting climate change. Forests regulate the climate, as evapotranspiration from forests influence precipitation patterns and the temperature. Many as yet underdiscovered plants may be of benefit to us as sources of useful products or drugs. Rain forests act as a refuge for vulnerable plant species, thereby protecting them from human over-exploitation and saving biodiversity for future human generations.
