Explanation The sympathetic nervous system is also called “fight or flight” division of the ANS and prepares our body for various stress responses. The sympathetic nervous system increases blood pressure by regulating the function of the heart and blood vessels. The neurons of the sympathetic nervous system release epinephrine and norepinephrine onto cardiac cells and smooth muscle cells of blood vessels. As a consequence, the heart rate and contractility increases, which in turn increases the cardiac output, thereby increasing blood pressure. The sympathetic nervous system increases blood pressure by causing vasoconstriction of all vessels with a more pronounced effect on arterioles...

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?
