Earth receives thermal energy from the sun via radiation. Which of the following is a result of this energy transfer?A. There is matter to produce carbon compounds on Earth.
B. Earth is a closed system in terms of energy.
C. There is energy to support life on earth.
D. Energy is created but not destroyed in the earth system

Answers

Answer: C. There is energy to support life on earth.

The earth receives thermal energy from the sun via. radiation. This energy is captured by chlorophyll pigments of plants and other organisms to conduct photosynthesis. The sunlight energy is necessary for synthesis of food in the form of glucose. The glucose is converted into chemical form of energy as ATP which is required for respiration process in plants. Photosynthesis and respiration both are necessary processes to sustain life of plants, which further support life of other living organisms. Therefore, energy transfer support life on earth.

The cycle of increasing trade restrictions among nations is known as a _________.a. tariff war
c. trade war
b. quota war
d. customs war

Answers

The questions says,' the cycle of increasing trade restriction among nations is known as .............. The correct option is C. Trade war is a situation in which nations make efforts to limit one another trade usually by the imposition of tariffs or quota restrictions. The trade barriers created limit trade between the countries involved.

A researcher is studying the impact of different community activities on natural resources. Which activity is correctly paired with the level of impact it has on natural resources?

A.little impact when humans exclusively use fossil fuels for power needs
B.great impact when humans use alternative water sources for nondrinking functions
C.little impact when humans plant different types of trees for different uses
D.great impact when humans maintain a diverse diet that includes various protein sources

Answers

Answer: B. great impact when humans use alternative water sources for non drinking functions.

Great impact when humans use alternative water sources for non drinking functions is the correct option because use of alternative water sources can deplete the overall available water for the present as well as for the future generation of the human population. This is against the concept of sustainable development which suggests that natural resources should be used in such a way so that these can meet the needs of the present population as well as that of future generation.

B) Great impact when humans use alternative water sources for nondrinking functions

The food web above represents feeding relationships in a biological community near a deep-sea hydrothermal vent. Hydrothermal vents are geysers on the seafloor that gush super-heated, mineral-rich water. The seawater surrounding hydrothermal vents typically contains carbon dioxide (CO2), molecular hydrogen (H2), hydrogen sulfide (H2S), and methane (CH4). Sunlight, however, fails to reach the seafloor where deep-sea hydrothermal vents are located.As part of an investigation, researchers collected living specimens from an area near a deep-sea hydrothermal vent. Mussels in the collection were found to be dependent on molecular hydrogen in seawater. Also, the researchers discovered multiple species of bacteria living in the gills of the mussels. Mussels use gills for filter-feeding and gas exchange with the surrounding seawater. On the basis of their experimental results, the researchers hypothesized that some bacteria living in the gills of the mussels are capable of chemosynthesis. Based on an analysis of the food web, an observation that deep-sea bacteria consume molecular hydrogen (H2) is most relevant to resolving which of the following apparent contradictions?Some organisms rely on energy captured from inorganic compounds to drive basic biological processes.Some deep-sea organisms appear to be primary consumers, but no plants live near the hydrothermal vents.
