They’re known as gateway drugs.
The hepatitis B and the human papillomavirus (HPV) vaccines are made this way. The vaccine is composed of a protein that resides on the surface of the virus. This strategy can be used when an immune response to one part of the virus (or bacteria) is responsible for protection against disease.Jun 28, 2016
First, there is a need to understand what the carrying capacity is as it relates to the environment:
- Carrying capacity refers to the maximum number of individuals of a particular species that and environment can support based on the resources it has.
- The population of a species in an environment grows and oscillates around the carrying capacity of the environment.
Now let us look at the graph. The population size grew from 0 and then leveled off at 2,000 with time. The leveling-off also happened without any oscillation, meaning that the maximum population size the environment can support is 2,000.
Hence, the portion on the graph that indicates the carrying capacity would be the plot where the population size is 2,000 and the time being between 12 and 18. This has been circled and labeled as 'K' in the attached image.
