Explanation:
Host-pathogen models resembels the host-parasite models and predator-prey which is used to evaluate the evolutionary strategies of pathogens.
The host-vector-pathogen system can be demonstarted as a change in the number of 4 types of people: healthy hosts, uninfected vectors, infected hosts, and infected vectors.
The threshold density should decrease by half, stay the same, or double, according to the standard host-pathogen model, if the combined death and recovery rate from a disease doubles, and the ability of the disease to spread from infected to uninfected persons.
Hence, the correct options are A. decrease by half, B. stay the same, and C. double.
An example of osmosis is when the water leaves the tubules of the kidney in response to the hypertonic fluid surrounding the tubules. Osmosis in the kidneys is a filtration. Osmosis will filter the water molecules and solutes in the kidneys from the plasma to the tubule. The other choices given are not an example of osmosis. The correct answer to this question is A.
