Answer:
A, O
Explanation:
O is oxygen, which is a gas at room temperature. It cannot conduct electricity as there are no delocalised electrons free to carry and electric charge.
A shield<span> is generally a large area of exposed Precambrian crystalline igneous and high-grade metamorphic rocks that </span>form<span> tectonically stable areas. In all cases, the age of these rocks is greater than 570 million years and sometimes dates back 2 to 3.5 billion years.</span>
Acid rain was an environmental hyperbole covering the effect of sulfur dioxide and nitrogen dioxide gasses being washed out of the atmosphere by rainfall. Downstream from coal-fired power generation and metal reduction processes, these gasses were part of the gas stack chemistry; sourced as minor constituents of the process coal. The pollutants were only measured in ppm quantities in major smoke stacks … famously I measured 200 ppm in the air from the Inco Superstack, measured over Toronto air space. Ontario has no coal plants or stacks left after environmentally forced decommissioning.
Phylogentic Trees are also called Evolutionary Trees. They're also a part of a group called Taxa.
Human impacts on biomes are best characterized by interruption of natural biome process.
<h3>What is a Biome?</h3>
An area of the globe that may be categorized based on the kind of plants and animals that inhabit there is known as a biome. What life there is in a biome depends on factors like temperature, soil, light, and water availability.
An ecosystem is distinct from a biome. An ecosystem is a habitat where living and nonliving things coexist. A biome is a particular geographical region distinguished by the organisms that call it home. Many different ecosystems can make up a biome. For instance, habitats like coral reefs and kelp forests can be found in aquatic biomes.
