Explanation and answer:
A rain shadow is a patch of land that has been forced to become a desert because mountain ranges blocked all plant-growing, rainy weather. On one side of the mountain, wet weather systems drop rain and snow. On the other side of the mountain—the rain shadow side—all that precipitation is blocked.
In a rain shadow, it’s warm and dry. On the other side of the mountain, it’s wet and cool. Why is there a difference? When an air mass moves from a low elevation to a high elevation, it expands and cools. This cool air cannot hold moisture as well as warm air. Cool air forms clouds, which drop rain and snow, as it rises up a mountain. After the air mass crosses over the peak of the mountain and starts down the other side, the air warms up and the clouds dissipate. That means there is less rainfall.
You’ll often find rain shadows next to some of the world’s most famous mountain ranges. Death Valley, a desert in the U.S. states of California and Nevada, is so hot and dry because it is in the rain shadow of the Sierra Nevada mountain range. The Tibetan Plateau, a rain shadow in Tibet, China, and India has the enormous Himalaya mountain range to thank for its dry climate.
Answer:
Federalism
Explanation:
Those who framed the constitution institute federalism as the system of governance so as to ensure that the powers of the government doesn't pose a threat to the liberty of the people.
Federalism is that system of governance which has a written constitution that divides the governmental power based on the territories between the regional government and the one at the center.
In this, both the central government and the state government exercise
their own powers separately.
Answer:
A). Innate behaviors.
Explanation:
As per the question, the 'innate behaviors' support the idea that behaviors play a significant role in the survival and thereby, influence the natural selection. Innate behaviors are elucidated as the inborn ability of an organism to display a particular behavioral response to a specific stimulus. Since these behaviors are genetically inherited and therefore, inflexible; it assists the animals in surviving as they may or may not be exposed to an environment through which they can learn a particular behavior. But <u>these 'inherited' abilities allow them to survive and select naturally even without training or experience(as required in case of learned behavior)</u>. Thus, <u>option A</u> is the correct answer.
