Hawaii sits smack dab in the middle of the Ring of Fire, a 25,000 mile boundary around the Pacific Ocean where tectonic plates meet to create volcanoes, earthquakes, and deep ocean trenches. Since Hawaii sits in the middle of the Pacific plate, not on a tectonic plate boundary, its volcanoes form in a different way.

Answer:
The 2 types of behavioral adaptation are migration, and hibernation.
Explanation:
Adaptation of animal is the fitness towards its environment. If an animal can't adapt, it will perish with time. Adaptation may be genetic or acquired. But basically, adaptation is 2 types - physical adaptation, and behavioral adaptation.
Physical adaptation includes the coloring of the body, camouflage activity of an organism. The behavioral adaptation is the respond of the organisms to their habitat. This includes hibernation, estivation, migration, etc.
Some animals are affected by the temperature difference of the environment. Therefore, they adopt some methods to survive in extreme temperatures.
The cold-blooded like amphibians hibernate during winter. They undergo a long sleep during cold weather and become active in summer. Similarly some animals like desert lizard active in the morning. When the temperature increase they burrow themselves under the ground. This is called estivation.
Birds migrate during the adverse season i.e. in winter. They temporarily go to a different place to spend the cold month and return during the advent of summer. This is one type of behavioral adaptation. They also migrate for better breeding ground and food.
Some fishes also migrate for breeding and food.

English Translation:
V: Virus, is a very small organism, which does not have the capacity to reproduce itself. This particular virus reproduces only by invading human cells, it does not affect animals. HIV is a fragile virus that cannot survive outside the body.
I: Immunodeficiency, because the effect of this virus is to create a deficiency in the proper functioning of the body's immune system. It infects and destroys immune cells, called T4, to grow and reproduce. It causes the organism to be defenseless, this situation is used by various infections and cancers to attack the organism and cause its death. These diseases are called "opportunists," because they take advantage of the weakness of the immune system to attack. Over time the virus weakens the person's defenses against the disease, leaving him vulnerable to many infections and forms of cancer that would not develop in healthy people.
H: Human, because the virus can only be contracted by humans. In the animal kingdom there are viruses with similar characteristics in apes and felines. It is believed to come from a specific type of African monkey.
HIV belongs to retroviruses. HIV can only replicate inside the cells, ordering the reproduction to the machinery of the cell. It belongs to the family of retroviruses, which means that it is able to reverse the direction of the information that normally flows from DNA to RNA, but in this case it does it in the opposite direction thanks to the reverse transcriptase, thus introducing its genetic code and through the integrase it "integrates" the code of the infected CD4 cell, which allows it instead of multiplying, what it does is produce new viruses, called virions.
HIV is a lentivirus. HIV belongs to a subset of retroviruses called lentiviruses, or "slow" viruses. The course of infection by these viruses is characterized by a prolonged period between the initial infection and the appearance of severe symptoms. It is known that from the moment of the initial infection it reproduces constantly, mainly in the lymphatic system.
Typhoid fever is a bacterial infection that affects the intestine and occasionally the bloodstream. The germ that causes typhoid is a variety of salmonella, called Salmonella typhi. The disease can be contracted by anyone, but the greatest risk is that of people who visit countries where the disease is common.
Answer:
P-waves travel through the fluid layers of Earth's interior, and yet are slightly refracted as they pass through the transition between the semi-solid mantle and the outer core liquid.
