Wind contributes the least!
Alik [6]3 years ago
4 0

Answer: D. Wind

Explanation:

The use of coal, natural gas and petroleum as fuel after combustion will liberate immense amount of greenhouse gases into the atmosphere. These greenhouse gases will trap the heat energy from the sun which will lead to increase in the global temperature. This scenario is called as global warming.

Wind is a renewable source of energy, it is abundantly available in nature. The speed of the wind currents can be used to generate electricity by the motion of the wind turbine. This form of energy generation does not liberate any form of gas into the atmosphere. Therefore, will contribute least to the global warming.

Which choice best summarizes the outcome of Reid’s experiment
Ilya [14]

This question seems to be incomplete because the experiment is not described but it is possible to answer it.

The correct answer is B. Redi disproved spontaneous generation.

Explanation:

Francesco Redi was an important scientist during the 17th century known for his experiments about maggots in rotten meat. This is because during Redi's time it was believed rotten meat was the origin of maggots because maggots seemed to emerge from this. Additionally, this perception was related to the spontaneous generation or the idea life can emerge from non-living materials. The results of this experiment show the idea about spontaneous generation was not true in the case of meat and maggots because maggots were simply the result of eggs flies laid on rotten meat. This means this experiment disproved spontaneous generation.

According to Max Weber, all governments get their powers from:
ryzh [129]

Answer:

The answer is: letter B, the people.

Explanation:

Max Weber is a German sociologist and political economist.  He proposed a theory on "bureaucracy." This is an organizational structure that focuses on rules, procedures, processes, hierarchies, etc. among the employees. He introduced the three types of power:<em> legal power, traditional power and charismatic power. </em>

According to him "power is the ability to exercise one's will over others." This definition has been adopted by many scholars over time. And for him, all governments get their power from the people. The word "power" here is different from the word "authority." Power affects social relationships and "it is NOT coercion." It provides a strategic way to rule the people so they will obey.

The Earth contains a great diversity of species. This:
True [87]

Answer:

The correct option is A) will make no difference in the survival of life if there were major changes in the environment.

Explanation:

Due to genetic diversity, variations in species are caused which makes some organisms of a species to be better adapted than other members of the species. These variations cause organisms to survive when differences in the environment occur. Although the allele frequencies might change due to the changes in the environment but the phenomenon of genetic diversity allows life to sustain on earth even when conditions will become unfavourable.
