Q:

What causes extinction?

A:

The heating and cooling of the earth, changes in sea level, asteroids, acid rain and diseases can all be natural factors that cause a species to become extinct. Humans can also be the cause of extinction for certain species.

When a species cannot adapt to changing conditions, such as changing temperatures, they will not be able to survive. This inability to survive will hinder the repopulation of their species and will eventually lead to extinction. Many species also cannot adjust to changing sea levels and the effects that higher sea levels have on the environment. High sea levels not only change the way that species function in the ocean, but also alter the environments that are within the ocean.

Humans are one of the biggest non-natural threats to species and their rates of survival. Humans are responsible for overpopulating the earth with their species. Humans are also responsible for deforestation and air pollution that can be detrimental to many different species. Humans also use other species for their survival, such as the use of meat from animals. Hunting for survival, in combination with other human factors and natural causes, can result in the extinction of many different species.

    How did the Triceratops become extinct?

    A:

    There are numerous theories regarding the extinction of the dinosaurs, including the triceratops, at the end of the Cretaceous period. The most prevalent theory describes the sudden destruction of the dinosaurs, and 50 to 75 percent of the planet's flora and other fauna, being due to a huge asteroid impact that dramatically altered the environment. However, despite strong evidence, there is no conclusive proof, explains the Smithsonian Institution.

    How did dinosaurs become extinct?

    A:

    Scientists can't say for sure what caused the extinction of the dinosaurs, but theories suggest that diseases, climatic change, geologic events and changing plant communities may be to blame. Scientists say that dinosaurs, along with 50 percent of all other life on Earth, died out around 65 million years ago.

    Why is it important for organisms to maintain homeostasis?

    A:

    Homeostasis is the process through which an organism maintains certain internal conditions, such as a human body's internal mechanisms maintaining body temperature at a specific level to prevent over or under heating; this process is important because it makes it possible for cells and organs to function properly. For example, certain parts of the human body cease to function if they become too hot or too cold; this is why it is possible for people to freeze to death or die from overheating.

    What is behavioral adaptation?

    A:

    Behavioral adaptation is the process by which an organism or a species changes its pattern of action to better suit its environment. It is contrasted with structural adaptation, which is the appearance of physical features that confer an advantage upon a species.
