Answer:
Charles Darwin
Explanation:
Natural selection, most famously proposed by Charles Darwin, states that when presented with an environmental challenge, some individuals in a species will develop adaptations to face these challenges. Successful individuals will be more likely to mate and their offspring will inherit these adaptive traits, and will continue to pass for generations.
In this sense, plants face the challenge of the cold. Those that adapt to the cold will survive and reproduce, those that can't adapt to the cold will die. Eventually, only plants that can tolerate the cold will survive.
Inflammatory response can be defined is a reaction of the body to injury or destruction of tissues. This reaction serves to dilute, destroy or simply wall off the agent causing the injury and is localized around the area of injury.
Inflammatory response takes place in the following steps:
1. Tissue damage caused by injury or bacterial infection is detected.
2. Vasodilators and chemotactic factors such as histamine are released.
3. As a result, there is increased capillary permeability and blood flow to the area.
4. There is migration of phagocytes to the site of infection.
5. Phagocytes and specific serum proteins attack and destroy bacteria.
6. Inflammation dies down once intruder has been destroyed.
Erosion and mixed composition. Wind,rain have a way of mixing and can create crystals
The answer to your question is solar radiation hitting the earth, a sphere which is tilted on its axis, puts into effect differential heating of the earth's surface. This affects weather and climate all across the globe. For example, the tropics along the equator get a lot more heat than at the poles. The air at the equator is heated.
