Answer:
When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive.
Explanation:
You might expect that sheltered areas of stone buildings and monuments would not be affected by acid precipitation. However, sheltered areas on limestone and marble buildings and monuments show blackened crusts that have peeled off in some places, revealing crumbling stone beneath. This black crust is primarily composed of gypsum, a mineral that forms from the reaction between calcite, water, and sulfuric acid. Gypsum is soluble in water; although it can form anywhere on carbonate stone surfaces that are exposed to sulfur dioxide gas (SO2), it is usually washed away. It remains only on protected surfaces that are not directly washed by the rain.
1 - introduced to a habitat similar to their own

<span>A psychological response to an out-of-the-ordinary stressor defines the posttraumatic stress disorder (PTSD).
When people are exposed to a traumatic event, such as war, or sexual assault, or generally any type of threat or tragedy, they may develop PTSD as a result. This means that the person will still have strong and negative emotions, such as fear, or hatred, months or years after the event occurred, and it is very difficult to treat.

Answer & explanation:
Non-native species may be animals, plants or microorganisms introduced into an ecosystem of which they are not originally part, but where they adapt and come to dominate, harming natural processes and native organisms.
When a new species is introduced into an environment other than its own, it may compete with others, prey heavily on some species, over-breed and even cause disease.
Therefore, it can be concluded that this action may cause the destruction of some species, directly affecting the balance of that ecosystem.

Purpose is it provides cells with the energy they need to function.
