Answer:
Option C, Each subpopulation is linked to all other subpopulations by dispersal.
Explanation:
Each sub-population with in a metapopulation is not only connected by the dispersal distance travelled by an organism but also by the distance between the patches on which two sub population live. There are several other factors that limitise the concept of connection of subpopulation by dispersal factor and these vulnerable factors are – properties of terrain between the patches and its adverse affect on the dispersal behaviour of dispersing agent/species.
Hence, option C is correct.
Carbon Dioxide is the gas that contributes most to the greenhouse effect.
A I believe because cars produce a lot of gas contributing to global warming
Answer:
The correct answer would be - "bacterial populations evolve in response to the selection pressure imposed by antibiotics".
Explanation:
The given information provided in the question about the bacterial infection supports the hypothesis that the bacterial population shows the evolution in response to the selection pressure caused by the antibiotics due to the fact that bacteria increased resistance gradually with time. This resistance towards antibiotics increased the percentage of bacterially infected children in the late 1980s and early 1990s.
In this case, the population of bacteria having resistance genes is selected to evolved selected to increase their offsprings.
