I believe it is behavioural isolation. When there are changes within a certain species, e.g. new birdcalls are formed in certain individuals in a species, "traditional" birds may not like such mating calls and only choose to mate with the more common birdcalls from majority of the birds. There are also some birds that may like the new birdcalls, and choose to mate with birds with those birdcalls. They become genetically isolated as they continue such behavior. Eventually, through genetic drift and other mutations, different species form from a single specie.
Hope this helps! :)

The correct answer is Polar climates.
The polar climate areas are featured by an absence of warm summers. Each month in a polar climate exhibit a mean temperature of fewer than 10 degrees Celcius. Even in their warmest months, they have a mean temperature of fewer than 10 degrees Celcius.
The countries coming under the polar climate regions are Alaska (United States), Yukon (Canada), Greenland (Denmark), Finland, Norway, Iceland, Sweden, and Russia.
The only answer that makes any sense is D. The rest of the answers do not make any sense. Be wary of answers that use the word "always." For example, domesticated swine are raised on farms and wild pigs live in the woods. But they are related and would have the similar genetics.
All living things need water and food. Light is nourishment for plants. They use it in a vital process known as photosynthesis, where chloroplasts capture the energy of light, sparking multiple metabolic reactions — one of which creates plant sugars (food).
So your answer would be A. Yes, sunlight helps plants to live
