Is defined as the group in an experiment or study that does not receive treatment by the researchers and is then used as a benchmark to measure how the other tested subjects do.
Answer:
<em>Differences in air pressure, due to differences in elevation, trigger the development of different types of caterpillars.</em>
Explanation:
A hypothesis can be described as a tentative statement which can either be supported by evidence from experiments or it can be discarded if the results of an experiment do not support a hypothesis.
In the scenario, mentioned in the question, the air pressure had nothing to do with the different type of caterpillars being formed neither was it the focus of the experiment. Hence, the above mentioned hypothesis will not be supported by the experiments.
The numbers that is represented after the species represents the number of question that should be considered next.
Answer:
D) Enzymes make nonspontaneous reactions become spontaneous
Explanation:
Being spontaneous or non-spontaneous in nature depends on the difference in energy levels between substrates and products of the reactions. A reaction with substrates at higher energy levels than the products are spontaneous ones. On the other hand, the reactions wherein products have higher energy content than the substrates are non-spontaneous.
Enzymes do not change the energy levels of substrates and products, so, they can not make a non-spontaneous reaction to become a spontaneous one. Enzymes only lower down the activation energy for a reaction and thereby make the non-spontaneous reaction to occur at a faster rate.
