Answer:
B
Explanation:
Vaccinations prevent sicknesses and transmission of the pathogen by injecting the body with a small amount of the sickness. The body develops antibodies, which prevent the body from developing that disease. If most people in a population are vaccinated, illnesses will spread less quickly because all bodies will have antibodies to fight them. To check, let's use process of elimination.
A: Pathogens are microorganisms that spread diseases, so they should to be encouraged to spread.
C: Although everyone should have access to vaccines, fairness is not as important as keeping the population healthy.
D: Pandemics are disease outbreaks that impact the entire or the majority of the world. Vaccines prevent them, not spread them.
Note: I used the words disease, sickness, and illness interchangeably.
Answer:
Diffusion
Explanation:
Diffusion is the movement of a substance (majorly liquids and gases) from a region of high concentration to a region of low concentration. Liquid and gases excluding solids can undergo diffusion because of their ability to move randomly. Diffusion is driven by a gradient in concentration.
For example gases can easily diffuse quickly and easily into another gas, because of its ability to move randomly. The foul air from the back room (higher concentration) was able to quickly spread into the clean air at the front row (low concentration) by diffusion
