The correct answer is: Disruptive selection
Disruptive selection is a type of natural selection that favors both extreme traits in a population (it is bimodal) over intermediate traits. In the example above, it favors dark and light-snails (both are extreme traits). As a consequence, the population of snails is divided into two distinct groups. This happens because snails with intermediate brightness wouldn’t have suitable environment for them, wouldn’t be adopted to either shady forest or brushy edge areas.
False, there is about 0.001 kilograms in a gram
Well there alot of challenges faced by biologist researchers during the research of infectious disease, however major of those include the followings:
1- Defining and measuring the fitness for pathogens across the scales
2- Developing models to capture the impact of co-infection on the evolutionary process
3- Modeling how pathogen characteristics shape the evolution of hose immune diversity
4- Understanding the maintenance of pathogen diversity
5- Developing the better models for the impact of genetic systems on pathogen evolution .
Since lizards are cold blooded, they will usually lie in the sun.
