Evolution is a process that occurs over many generations.

Expert Solution & Answer

Explanation of Solution

Many generations have to go through selection (natural selection or artificial selection by scientists) for evolution to occur. If a particular trait gives an organism an advantage in survival, it will become common in the population. Organisms with a short lifespan are preferred for the study of evolution because such organisms reach maturity soon. Therefore, many generations of organisms can be included in the experiment. On the contrary, if an organism with a long lifespan were to be chosen for study, it would take years to perform the experiment.

Conclusion

As seen in the starvation experiment, the study of organisms with a short lifespan allows the researcher to include many generations in the experiment.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
