Answer:
Two possible reasons for the massive extinction at the end of the Paleozoic Era are an asteroid collision and massive volcanic eruptions.
Explanation:
The massive extinction that occurred at the end of the Paleozoic Era is the biggest extinction from what is known so far. The majority of the species died out, and whole families of animals and plants were wiped out of the face of the Earth. It was only small and highly adaptable organisms that managed to survive and give rise to the later life-forms.
The two possible reasons for this massive extinction are an asteroid impact and massive volcanic eruptions. An asteroid collision would have created drastic changes in a matter of minutes and hours, with effects lasting for a long period of time, thus eliminating the majority of the life. Massive volcanic eruptions, with the Siberian super-volcano being the prime candidate, may have caused enormous amounts of carbon dioxide and sulfur dioxide to end up in the atmosphere, thus rapidly changing the living conditions on the planet.
Answer:
Mimicry
Explanation:
Living organisms are known to be able to adapt to the natural environment in which they exist over time. One of the adaptation techniques is called MIMICRY. Mimicry is a type of physical adaptation whereby an organism (animal) looks similar in appearance to another organism in order to discourage or push away predators.
This is the case of the viceroy butterfly in this question, which has coloration that is almost identical to the poisonous monarch butterfly. Although, the viceroy butterfly is not poisonous but its coloration that looks like poisonous monarch butterfly makes it appear poisonous to predators. Viceroy butterfly is said to mimick the poisonous monarch butterfly in order to deceive predators.
If you have choices, it would be really helpful if you'd include them with your question, but I'd say
More than half of the forests in the Czech Republic have been destroyed by pollution.
This is due to the amount of infrastructure in the city. All that metal holds heat making inside the city hotter than outside the city.
Population distribution and density patterns can be useful to understand because they help to explain how and why people migrate and develop in certain places around the world. These factors influence human migration and development and are therefore important to understand if you seek to understand how the world has developed over time and what are the forces that are driving this development.
