question 34

Multiple Choice

Read the following scenario and answer the question below
Human activities, including fossil fuel combustion, farming, and deforestation, are known to increase the levels of carbon dioxide, methane, and nitrous oxides in our atmosphere. Measurable warming of Earth due to these greenhouse gases can alter ecosystem dynamics. In addition to the direct climatic effects on organisms within biomes, warming can lower levels of sea ice and increase precipitation in Arctic areas. Global warming also can melt permafrost in the tundra and increase sea surface temperatures, which could increase the intensity of hurricanes in vulnerable areas. Within communities, climatic change can shift interdependent species "out of sync," potentially causing indirect loss of species. For example, if pollinators and the plants they pollinate become out of synch, the pollinators may not be able to use a different food source, and the plants may not be able to reproduce.
-Intense hurricanes resulting from global warming can directly lead to _______________ within communities.

• A)coevolution
• B)secondary succession
• C)facilitation
• D)primary succession
• E)climax

Definitions:

Adenine

A nucleobase (a building block for DNA and RNA) that pairs with thymine in DNA and with uracil in RNA.

Hydrogen Bonds

A type of weak chemical bond formed when the slightly positive hydrogen atom of one molecule is attracted to the slightly negative atom of another molecule, often oxygen or nitrogen.

Guanine

One of the four main nucleobases found in the nucleic acids DNA and RNA, characterized by its ability to form three hydrogen bonds when paired with cytosine.

Cytosine

A nitrogenous base found in DNA and RNA molecules, pairing with guanine in the genetic code.
