Compare and contrast: vaccines versus antibiotics mark each statement as true for either (v)vaccines or (a)antibiotics. a. work only against bacterial infections. b. work primarily against viral infections. c. immunity is provided by injecting a killed or live attenuated (weakened) type of pathogen into a person. the person’s own immune system then creates antibodies against that pathogen that keep them from becoming ill when they come in contact with it in the future. d. if used improperly, can cause bacteria to mutate and become resistant to the medication. e. work because of the types of memory cells in our immune system.

What substance acts to prevent sudden ph changes in bodily fluids?

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
