Answer:
The Miller-Urey experiment was conducted to simulate the conditions on Earth when life arose, and see if a chemical evolution could occur. This experiment was performed without oxygen, because they knew that if oxygen was added, the amino acids would oxidize. In particular, the experiment intended to simulate a volcanic eruption was analyzed.
Thus, particles of water, methane, ammonia and hydrogen were exposed to high temperatures and electric discharges that simulated these eruptions, during a determined period. Later, it was observed that organic compounds had emerged from this exposure, which allowed us to infer one of the hypotheses regarding the origin of life on Earth.
Answer:
limiting factors
Explanation:
They are called limiting factors, because they limit the amount of food resources and/or organism amount in an area or ecosystem.
Answer:
Explanation:
The scientific method. When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis often in the form of an if/then statement, the results aiming to support or contradict a theory.
Astronomy can best be described as a "<span>a. study of objects beyond earths atmosphere", although the subject of astronomy can be much more complicated. </span>
Answer:
1-<em><u>An energy audit is an inspection, study and analysis of the energy flows in a building, process or system with the aim of understanding the dynamic energy of the system under study</u></em>
