True. Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell.
A significant resistance mechanism in Gram-negative bacteria is drug efflux. It expel solutes from the cell. Antimicrobials and metabolites are just a few of the hazardous compounds that Efflux pumps help bacteria remove from their interior environments so they can regulate it.
The main efflux systems in Gram-negative bacteria are members of the RND superfamily and typically consist of an outer membrane protein channel, a periplasmic protein, and a cytoplasmic membrane pump. The most common example is MFS (such as Bmr and Blt in Bacillus subtilis) and the ABC transporters.

Answer:
the gar population will increase, the diving duck will decrease slightly and the crab population will decrease
Explanation:
Since the alligator population will decrease, the gar population won't have anything to limit their population, so they will increase fast. The crab population will decrease fast as there are more gars to eat them. The duck population will decrease slightly as the gar is eating more crabs then the duck

Animals contribute water vapor back into the atmosphere by respiring, breathing out water vapors that rise to the atmosphere. They're perspire to prevent overheating; during this process, water is excreted through the pores and evaporates off the skin, cooling the animal by absorbing the external heat.
