Answer:
The researcher's claim is in the same way of the observation made because from it it is inferred that in a population of bacteria with genetic variation, in which some of them have plasmids and others do not, the population survives because those bacteria with plasmids are resistant to antibiotics, if for example there were only bacteria without plasmids all bacteria would die when using antibiotics so this is an example that genetic diversity is an evolutionary advantage
Answer:
D. altering it to fit within the hypothesis
Explanation:
An experiment is carried out to fill an inquisition i.e. to answer a question. According to the scientific method, prior to experimentation, there must be a HYPOTHESIS. The hypothesis is tested for rejection or approval via experimentation.
After the experiment has been conducted, several things can be done with the data obtained. For example:
- Data can be interpreted
- the data can be plotted in a graph to find correlations
- It can be analyzed it with statistical analysis.
One thing that should never be done is; altering the data from experimentation to fit in the hypothesis.
Answer:
Earth formed about 4.6 billion years ago during the birth of our solar system. ... During the next major phase of earth's formation cooling and differentiation of the Earth's layers occurred.
