Question: Jezelyn needs to create a project that shows reproductive isolation in action and decides to make a video. Which of the following would make the best project?
a video that shows a large river that has penguin populations on both sides
a video that shows penguin species that have different mating dances a video that shows
a penguin that is laying eggs a video that shows penguins in a tidal pool and an open ocean
Answer:
The right option is a video that shows penguin species that have different mating dances.
Explanation:
Reproductive isolation is the inability of animals of closely-related species to interbreed with one another successfully as a result of various differences which can be ecological, behavioral, psychological, or genetic. From the question given above, the difference in the mating dances of the penguin species will not allow the animals to unite and mate. This condition describes reproductive isolation. Reproductive isolation is caused by mating differences, sterility or environmental barriers that eventually lead to the adaptive splitting into two species. However, reproductive isolation is not sufficient but internal barriers to gene flow are required for speciation to evolve.
Where are the answer options and a picture of the problem?
Answer:
Question one: Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change. Question two: If those resources limit growth, then increasing functional richness should lead to greater total productivity and decreased loss of resources from the ecosystem. Facilitative interactions among species could also lead to increases in ecosystem pools or process rates as species or functional richness increases. Question three: Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution.
