Answer:
The two main objectives of scientific investigation are knowledge production and hypothesis development. Science uses a wide variety of persons and settings to conduct its investigations. There are numerous methods for conducting scientific research, all of which rely on the collection of various types of data. 
Human error can occur when measurements are made improperly or when observations are incorrectly recorded. Scientific fraud is the term for deliberate data manipulation. Bias, or prior conviction that the hypothesis is correct or false, can have an impact on the accuracy of observation and the interpretation of data.

There are two branches of the autonomic nervous system, namely the sympathetic nervous system and the parasympathetic nervous systems. Both of which regulates bodily functions involuntarily but in different manners. The parasympathetic system is the system primarily activated in "relaxed" states or "rest and digest" states. These include digestion, urination, slowing of heart rate, slowing of respiratory rate, etc. The sympathetic nervous system on the other hand is primarily activated by "flight or flight" response such as rage or fear. These include inhibition of digestion, increase in heart rate and respiratory rate, sweating, etc.
