Answer the following statements true (T) or false (F)
1. All rain forests are tropical. 2. The same biome cannot occur on more than one continent. 3. Only temperature can limit a species' fundamental niche. 4. Microclimate is a term used to describe local variation in climatic conditions. 5. The range of the sugar maple could decrease in response to warming due to climate change.
The antibiotic rifamycin is selectively toxic in blocking protein synthesis in Mycobacterium tuberculosis because
A. the antibiotic binds to the mRNA once synthesized, preventing it from participating in the initiation complex with the ribosome. B. it binds preferentially to bacterial RNA polymerase rather than the eukaryotic protein, effectively halting transcription in the pathogen but not the host. C. bacterial ribosomes are 70s whereas host ribosome are 80s, thus the antibiotic binds to the M. tuberculosis ribosome but does not bind to the eukaryotic machinery. D. the drug binds to the initiator tRNA, preventing the formation of the protein synthesis initiation complex in the bacterial cell.
