the purpose of the development of a vacuole is correct answers digest food, regulate excess water and regulate internal environment if a virus that normally infects cells in the lining of an elephant's lungs enters a rhinoceros correct answers it cannot infect the rhinoceros because a virus is specific to a cell type and a species photoheterotrophs get their energy from blank and their carbon source is correct answers light carbon source chloroplast arose twice on a phylogentic tree ma...

Hershey and Chase performed an experiment in order to determine how bacteriophages infect bacteria. What did they find? CORRECT ANSWER The bacteriophage injects DNA into the host cell. This was found because, after centrifugation, the pellet was radioactive The largest difference between a Gram + and Gram - bacterial cell is: CORRECT ANSWER The gram + cell has a much thicker peptidoglycan layer Why does a Gram + cell stain blue/purple in a gram stain? CORRECT ANSWER The Gram + cell stains ...
