Answer:
The majority of marine organisms are found in coastal regions.
Explanation:
The majority of marine organisms are found in coastal regions because ocean flows bring nutrient-rich water into coastal areas. Marine coasts are the type of environments that change through the weathering process and change in sea levels. Coastlines mostly consist of continental shelves that contain relatively shallow waters of having 200-meter depths only.
Since water is shallow here, photosynthetic processes are possible for marine life, which attracts more organisms to their primary food sources. Since the land is near shallow waters, discharges of nutrients from the soil are brought into the sea for the marine organisms so that they can use it. Aside from these reasons, cyclic upwellings in the sea also provide fresh and nutrient-rich waters for several species.
Answer:
C
Explanation:
In this question, we want to select which of the options that correctly attributes recent changes in climate to human activities
The correct answer is that global climate models can only reproduce recent temperature increases when anthropogenic green house gas emissions are included as forcing
What we have here is that for the models to show a pattern of temperature increase that we have seen recently, there must be a substantial effort by humans to have increased green house gases emission as a direct result of their activities
So this clearly put in the pattern detection of temperature increase by the model as a result of human actions thereby directly attributing what the model has developed as a result of what men has put into action
Answer:
b. behavioral isolation
Explanation:
It is a type of reproductive barrier that can lead to speciation. Behavioral behavior, such as mating rituals as in when two populations of the same species show some difference in behavior, typically in mating rituals
and signals.
A. describes the quantities of natural resources available
