The appropriate answer is c. global warming. Global warming is an increase in the global temperature caused by the increased use of fossil fuels. Using fossil fuels since the industrial revolution has pumped extra carbon dioxide in the atmosphere than what would actually enter from natural processes. This extra carbon dioxide is increasing the green house effect and causing the temperature to increase.
1.Magnification is the ability of optical instruments, such as a telescope or a microscope, to make an object bigger while resolution is the ability of optical instruments to produce images that are clearer, finer, and sharper.
2.Resolution is the power of an optical instrument to capture and produce more details of an image while magnification is the power of an instrument to create and produce a much larger image of an object.
3.Resolution can be expressed in arcsec or seconds while magnification can be expressed by a whole number and the letter “X.”
4.Although both are dependent upon each other, a high magnification does not always guarantee a high resolution.
5.Magnification allows us to see small objects, especially those that are not visible to the naked eye, while resolution allows us to see these objects more clearly and with more details.
A scientific theory changes when there is more information available about what the theory covers.
· Abiotic factors are nonliving, such as temperature, sunlight, and soil in an ecosystem.
· Biotic factors are the living parts of an ecosystem, such as plants and animals.
Given the above, the biotic factor listed is evergreen trees in a coniferous forest.
The other options - soil, precipitation, and temperature - are abiotic.
