Answer:
Isolation
Explanation:
On a island, there are three mice population in which one population cannot contact other populations. This situation is an example of allopatric speciation.
What is Allopatric speciation?Allopatric speciation is also referred to as geographic speciation. It is also called vicariant speciation. Allopatric speciation is a mode of speciation which occurs when the biological populations become geographically isolated from each other to an extent that it prevents or interferes with the normal gene flow in a population.
There are several factors which are required for the allopatric speciation to take place such as isolation of a population, time, and natural selection in an environment. Earthquakes, floods, and migration all are the ways through which a group of individuals of the same species can become isolated.

Warm fronts cause several days of cloudy weather, while cold fronts cause heavy snow in the winter.
Warm fronts cause thunderstorms in the summer, while cold fronts cause rain when the air is humid.
Answer:
Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather.
Explanation:
i'm pretty sure
Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather. So, the correct option is B.
What are Warm and cold fronts?A warm front forms when a mass of warm air enters a space that previously held cold air. As warm air passes over cooler air, it rises and cools, which can result in the formation of clouds and precipitation. Unlike a cold front, a warm front often brings with it lighter and more widespread precipitation. Warm fronts often bring warm temperatures and high humidity levels.
When a mass of cold air approaches an area that was previously surrounded by warm air, a cold front is formed. When cold air flows into warm air, the warm air is forced to rise rapidly, which can result in thunderstorms and heavy rainfall. More extreme weather changes, such as a sharp drop in temperature and drop in humidity, are often brought about by cold fronts.
So, the correct option is B.

What process occurs when a river velocity increase and why
Answer:
Flood Erosion and Deposition: As flood waters rise, the slope of the stream as it flows to its base level (e.g., the ocean or a lake) increases. Also, as stream depth increases, the hydraulic radius increases thereby making the stream more free flowing. Both of these factors lead to an increase in stream velocity.
