Answer:
Theories develop through repeated experimentation.
Explanation:
<em>The correct answer would be that t</em><u><em>heories develop through repeated experimentation.</em></u>
A theory is internally consistent and is only arrived at after several independent experimentation based on the same phenomenon. That is, when a scientist reports a findings, the reports must have been widely tested by different researchers using the same experiment and arrive at similar findings before they can become a theory.
Hence, the information on the theory explaining the movement of sand beaches is valid because the experiment must have been repeated by several independent researchers and similar results must have been obtained before the theory is arrived at.
Answer: Rosa's errors were options
A: Wind does not easily produce a lot of electricity.
C: Geothermal energy causes a lot wind pollution.
Explanation:
Wind Energy is the use of wind (kinetic energy) to provide mechanical energy and electricity through wind turbines. The wind turbines in a Wind farm ( made up of several wind turbines connected together) are then connected to electric power transmission network to generate electricity to households and grids.
Electricity is measured in Mega Watts (MW); Rosa is wrong because wind energy amounts for a significant percentage of electricity used in some developed worlds and mostly the European Union (EU) at a recorded 270 Giga Watts (GW). It is estimated that by 2020, wind energy will produce 50 percent of energy used by the EU.
Geothermal energy is the thermal energy (temperature of matter) which is gotten from energy generated and stored in the earth. Geothermal energy comes from radioactive decay of materials and the formation of earth.
Rosa is wrong, because Geothermal energy is environmental friendly and does not cause significant pollution. It does not involve fuel to harness its energy which in turn leads to stable electricity prices.
The answer is the first choice: Blue Eyes.
Polygenic traits are those controlled by two or more genes (hence the name "poly" in the term). Other examples would be skin color and height.
Hope this helps! :)
Answer:
Option (C)
Explanation:
Biodiversity usually refers to the different varieties of life forms that exist on earth. This includes the varieties in terms of ecosystem, and species and genetic changes.
This biodiversity is directly dependent on the region where there occurs a high amount of sunlight and precipitation. The factors such as latitude, climate, height, availability of resources are important for the growth and expansion of biodiversity. In these regions, the biogeochemical cycle also occurs rapidly, as the processes that are associated with it occur at a faster rate, thereby enhancing biodiversity.
Thus, the correct answer is option (C).
