Penicillin acts against bacteria by suppressing their enersy metabolism 4. Anaerobic bacteria would not have to form heterocysts to fix nitrogen. 5. Saprobes parasitize plants 6. Their high mutation rates allow bacteria to adapt to changes in their environments 7. If a cell infected with a virus were treated with a drug that blocks mRNA translation, the virus would still be able to reproduce. 8. Humankind's most prevalent disease is caused by an apicomplexan. 9. Photosynthesis by protists supports aquatic food chain. 10. Many fungi depend on plants for mineral absorption. 11.The evolutionary advantage of brightly-colored fruits is that bright colors aid seed dispersal 12.
