I believe the answer is a. thick layer of blubber
Mammal is an warm-blooded animal that need to keep their body warm. Organ that could insulate the heat would be beneficial to keep the temperature, like layer of fat or thick fur. The example of marine mammals would be dolphin, whale, sea lion and polar bear. Thick fur will not give much benefit for mammals in water, so only polar bear have thick fur. But all of them has thick layer of blubber, so option A will be the most appropriate.
Answer:
Its people would leave and migrate to other locations
Explanation:
Those areas where amount of precipitation having less than 8 inches, these areas are the arid regions. In these areas, water is present in very low amount which is not sufficient for the needs of high population. Minimum agricultural should be done because planting and growing of crops need a lot of water so most of the people migrate to other regions where water is present in large amount.
In this experiment, researchers compared how fast the junco populations adapted.
<h3>What is the focus of the study?</h3>
This study focuses on the adaption process of Juncos (a specific bird population) in urban environments and how they behave in terms of stress and boldness behavior (interest in exploring unknown areas).
<h3>How did the study work?</h3>
In this study, scientists compared the behavior of a population of birds in an urban area with the behavior of another population of birds that lived in a novel urban area to determine the adaptation process of the second population.
Note: This question is incomplete because the information about the study is missing; here is the name of the possible study: Boldness behavior and stress physiology in a novel urban environment suggest rapid correlated evolutionary adaptation
